CHKDSK is an internal service subroutine of the Windows 7 operating system, which is used to verify local drives? Which were created when defragmentation of the hard disk, for errors of the selected file system (NTFS, FAT32). The very name is a shortened merger of the two English words "Check" and "Disk", which are together translated into Russian, how to "check the disk". Not all users know how to run Chkdsk on Windows 7. Therefore, consider detailed instructions on how to do it.

Note that this subprogramme allows not only to find, but also to correct the file system errors found. It can also restore damaged local disk sectors. It can be launched in two different ways.

Directly through "Computer"

To start this subroutine, this method must be necessary in order to make the following actions described below:

1. You need to double-click the left mouse button twice, hovering the cursor, on the computer icon on the desktop or through the Start menu:

1. As a result of clicking, the dialog box will open, in which existing local discs will be shown, each of which can be checked using the subroutine under consideration:

1. Next, bring the cursor on it, click the left mouse button to select the disk. Then click the right mouse button without removing the selection from the disk. As a result of clicking, this context menu appears:

1. Next, in this menu, you must click on the item "Properties":

1. After clicking, the dialog box will be displayed, in which you need to go to the "Service" tab and click the "Check" button:

1. By pressing, another dialog box appears in which you can put ticks in the additional options for checking the disk, and then click the Runway button:

Note! If you check the local disc to which Windows 7 is installed, then the check will be started only when you turn on or during a reboot, since all OS processes are accessed during operation.

The result of the actions of the actions will be checked the selected disk on the errors that will be corrected in the case of selecting the appropriate option.

How to run chkdsk from the command line?

To start the subroutine in this way, you must successively perform the following steps:

1. We go to the "Start" menu and in the "Find Programs and Files" field, type "Cmd" (without quotes) row on the keyboard:

1. As a result of entering, an appropriate service internal subprogram of OS will be found:

1. Next, click the right mouse button on the subroutine found and select the "Run on behalf of the administrator" in the menu that appears:

1. At this step on the monitor screen, the following functional OKCHO will be displayed:

1. In this dialog box, you must, using the buttons on the keyboard, dial the string " cHKDSK C: / F"(Without quotes), where C is the name of the local disk checked, / F is a built-in command that initiates the elimination of the errors found. After entering, press the "ENTER" button on the computer keyboard:

1. As a result of clicking, the corresponding process will start.

Note! If the OS is installed on the local disk, the check will be interrupted and will be prompted to perform it when rebooting. If the disk is usual, the check will be started and in this dialog box will display the entire verification process.

Scenario: You have system errors, and they need to be corrected.

Utility of checking and correcting errors on the hard disk of Microsoft CHKDSK ("Disk Check") was presented more than 30 years ago, but still used. Even the users of the latest versions of the Microsoft operating system can use this command to check your hard drives for errors and correct them if necessary. Below is the instruction on the launch of CHKDSK in Windows 10.

If after using the chkdsk utility you still have errors, try.

First select "Search in Windows" and search for a command line by entering "CMD". Click on the label right-click and select "Run from the administrator" in the context menu.

After logging in as an administrator, you will find yourself on the Windows command line, familiar users of operating systems to Windows NT. Enter the "chkdsk" command, press the space, and then the drive letter you want to check or fix. In our case, this is an external disk "L".

The execution of the chkdsk command without arguments will only show the disk state, and will not correct the errors present on the section. To ask CHKDSK to correct disk errors, you need to specify the parameters. After entering the letter, enter the following parameters, each of which is separated by a space: "/ f / r / x".

The "/ F" parameter specifies the CHKDSK to correct the errors found; "/ R" indicates the program to detect damaged sectors on the disk and restore information that it is possible to read; "/ X" makes the disc unmount before the start of the process. Additional parameters are available for more specialized tasks, and are described in detail on the Microsoft Web site.

As a result, the complete command you want to write a command line looks like this:

chkdsk [Disc:] [Parameters]

In our case:

cHKDSK L: / F / R / X

It is worth noting that CHKDSK must block the disk, so it will not be possible to check the system boot disk if the computer works. In our case, the target disk is external, so the process will begin immediately after entering the command. If the target disk is bootable, the system will ask you if you want to run the command before the next load. Enter "Yes", restart the computer, and the command will start before loading the operating system, receiving full access to the disk.

The execution of the Chkdsk command can take a long time, especially on large disks. Upon completion, the program will summarize the results, such as the total volume of disk space, byte placement, as well as the most important thing - information on found and fixed errors.

The chkdsk command is available in all versions of Windows, therefore users like Windows 7 and Windows XP, can perform the above steps to initialize the tesh disc. In the case of using old versions of Windows, you can do the following:

1. Press "Start - Run ..."
2. Enter cmd.
3. Enter chkdsk [Disc:] [Parameters]

Stages "chkdsk"

5 main steps are described below:

Stage 1. Check the basic file system structure ...

At the first stage, files with entries in the MFT (main file table) are compared and checked.

Stage 2. Check file link links ...

At this stage, directories and structure are checked. They are checked for compliance with the size of the file and the time stamp of information.

Stage 3. Check security descriptors ...

At the last stage of verification (3), files and folders are checked for security descriptors, including information about the NTFS rights owner.

The fourth and fifth stages are performed only if the argument / R!

Stage 4. Search for damaged clusters in user files ...

Cluster sectors, including data, are checked for use.

Stage 5. Search for damaged and free clusters ...

At the fifth stage, the cluster sectors are checked for the absence of data.

If it is impossible to solve problems with a hard disk using "chkdsk", it is recommended to use the appropriate manufacturers.

Also in Windows you can access the chkdsk graphic interface

To check with a graphical interface, do the following:

Right-click on the disk you want to check. Select Properties - Tools - perform check.

This is a graphical interface "Chkdsk". Two options correspond to the "/ F" and "/ R" parameters.

How long does Windows need to boot? Sometimes it seems that it takes the whole eternity. There are several methods for accelerating the system loading, but it is possible a problem is that your computer performs the CHKDSK function with each download.

Have you noticed a fill strip during waiting? Does it appear often? Have you ever wanted to know what it is, because of what happens and whether Windows needs to actually perform it? Read this article, and we will answer all these questions together.

Imagine that the disc is a hall filled with wardrobes for storing documents. Sometimes files do not fall into those boxes, and sometimes these boxes break. Suppose a person who used the room yesterday took several files and put some of them not in those places, and some left to lie on the floor. Perhaps he did not carefully applied with drawers. This is what happens when you turn off the computer using the power button, instead of doing this through the Start menu. Most people do it because their Windows turns off too long.

Now you need to go there again and do some research. You open the door and frozen on the place with an open mouth. And then you think: "I just can't do it today." This is what happens with your computer when its file system is in disarray. And now imagine that you have a colleague, the only task of which is to sort files and fix boxes. This colleague will call Check Disk.

Let's continue our analogy with the chamber filled with cabinets. Can Check Disk perform his work when several people work in this room? Of course not. He will not be engaged in this after 5 hours, when everyone leaves home and power turns off. Therefore, Check Disk comes early in the morning, just before everyone else, and checks whether everything is in order.

That is why Check Disk is triggered when you start your computer. Unfortunately, Check Disk is a little lazy and will not correct the errors and restore the files if you do not require it clearly. This is done by adding command line flags, for example, / f to correct disk errors and / r to restore information from damaged sectors

Why does CHKDSK run on each download?

So something is wrong with your disc. This is a short answer.

What really is the problem, say not so simple. Perhaps an important system file was damaged or removed. Maybe too many damaged sectors appeared on the disk, with which nothing is done. Remember Check Disk will not correct errors if you do not give him such a task. While the problem is not solved, Windows will try to determine the reason for its occurrence, launching check DISK with each download.

The work of Chkdsk takes the whole eternity. What to do?

Just wait. In Windows 7 and earlier versions, watches or even days could be held on a complete check. The utility checks each file on your computer, and the more compatible disk, the longer the time it goes. Interrupting this process, you do not allow the program to perform your work. Therefore, when you turn on the computer next time, Check Disk will start checking from the very beginning.

How to disable the launch of CHKDSK with each download?

The answer is simple - correct the problems encountered in Windows. Perhaps the problem is only one, but there may be a dozen. It is not known in advance what actions you have to do, so let's consider the easiest and frequently applied solutions.

Make sure the chkdsk is not planned task

Although the likelihood of this is low, check this assertion is the easiest way. Run job scheduler by opening start menu and entering the search string " task Scheduler" The utility should appear in the search results. Click on it to open.

Most likely, you have to tinker to check if Check Disk is in the task list. In the screenshot below the utility is easily noticeable, because I added it myself. Click on the desired string right-click and select " Delete" That's all. But if it did not help you, read on.

It may seem that we repeat, but it is not. A single start of Check Disk can be scheduled to the next load. To make sure that you will need administrator rights and command line. Click on the button Start And find the command line. It should appear in the search results as cmd.exe.».

This article suggests that the tag of the volume of your hard disk is C:. Take it into account before continuing.

When the command line is started, enter

and press ENTER. If you see the following message, it means that the Check Disk start is scheduled for the next boot.

File System Type: NTFS.

Starting the chkdsk utility for Tom C: manually scheduled to the next load.

If you get the following message, then launch the program not Scheduled and this is good. However, you can still fulfill further instructions to make sure that everything is in order with the disk.

File System Type: NTFS.

Errors on C: not detected.

You should allow Check Disk to do your job, but if the utility causes you too much inconvenience, cancel the launch. In the command line window, enter

then press the key ENTER. This will prevent the launch of the Check Disk when the system is then loaded.

Run chkdsk with faithful flags

If the launch of Check Disk will occur still, you can order the utility to correct all the errors found and try to restore data from damaged sectors. For this you will need administrative rights. The following are instructions for Windows 7 and earlier versions, and then for Windows 8 and later.

If you are not sure which drive is installed, check whether it is a solid-state disk ( SSD.) or hard disk ( HDD.). If your computer has an SSD, you can still use Check Disk, but it is not necessary to start checking with the flag / R.. Between SSD and HDD there are some differences, in particular, SSD does not have moving parts.

The SSD does not include a physical disk, so it does not need to check the CKDSK C: / R command. However, Windows uses the same file system both on SSD and HDD, so you can fix the file system errors using CHKDSK C: / F. With the exception of this, Check Disk is not necessary.

In Windows 7 and earlier versions, the check may take some time. Perhaps an hour, and sometimes a whole day or even more, so make sure you have free time. Do not interrupt the work of Check Disk after it started.

To start the utility, click on the Start button. In the search string, enter " command line" It should appear in the search results. Click on the command line with the right mouse button and select " Run on the name of the administrator».

After the command prompt window appears on the screen, enter the command

and click ENTER. Thanks to the flag / r, the program will try to restore information from damaged sectors, as well as correct all disk errors, so you do not need a flag / f.

The command line will tell you that it cannot perform this action, since the specified volume is now used. Then she will ask if you want to schedule a volume check for the next load. Enter Y. and press ENTERTo schedule Start Check Disk with error correction option.

Restart the computer and wait until the utility will work. After checking, all errors must be corrected, and Check Disk will no longer run when loading, if, of course, there are no other problems.

Windows 8 copes with such problems more efficiently. The file system constantly checks itself for errors. Errors that do not require disc disconnection are corrected immediately. Fixing other errors that can be performed only when loading is scheduled for the next system launch.

Since the system needs to be corrected only by those errors for which the disc disconnection is needed, Check DISK performs its work in a few seconds or minutes. To do this, click Start. Enter " cmd.»In the search string of programs and files. The top of the search will be cmd.exe.. Click on the row right-click and select " Run on the name of the administrator».

To make sure that all other problems are found and solved, first start checking the disk by executing the command.

chkdsk C: / Scan

and pressing the key ENTER. During scanning utility, the utility will fix everything for which the disk is not required. After checking checks, enter the command

chkdsk C: / Spotfix

and press ENTER. You will see the text reporting that this volume is busy with another process. The command line will then ask if you want to schedule a disc check to the next system loading. Enter Y. and press ENTERTo schedule Start Check Disk. Now restart your computer.

This time, Check Disk will start and correct all the errors found during the scan. And since the utility remains to correct only errors that require disconnecting the disk, it will take just a few seconds or minutes.

Now with your file system should be all right. Check DISK will no longer run when the computer is turned on, if there is no other problems.

Check if it helped

After completing the Check Disk, there is only one way to check whether the utility has fulfilled its task - rebooting the computer. Let's hope that the program will no longer start, and you can continue your affairs. If Check Disk continues to run, you may have more serious file system problems, or errors associated with the registry or the operating system itself. You should consider the option to restore the system or a complete reinstalling Windows. Maybe it's time to change the hard disk. Of course, this is an extreme measure, but she definitely solved your problems.

This article helped you correct emerging problems? Did you find other ways to stop the launch of Check DISK on each download? Maybe you have any questions? Share them in the comments, and we will be able to help each other.

The following lesson helps you cancel the constant launch of the Chkdsk utility when booting Windows 10/8/7. Although the disc check will be very useful because it periodically checks the presence of errors and system failures. But when you turn on your computer, you will receive the default 8 unnecessary seconds to check the disk. Check Disk Utility or chkdsk.exe utility in Windows 10/8/7 is used to check for disk and file system errors.

In such cases, you can cancel the planned DSKCHK when loading. To cancel the disk check, you need to first determine if any disk has all the scheduled checks. Once you define, you can simply press any key to skip the disc check to the next restart session.

If you are encountered with different problems, starting from the blue screen and the inability to open, save files or folders, you must run the CHKDSK program. In the case of a sharp stop of the OS or if it finds problems with the file system, then check the disk to start working and automatically. There may also be cases when you may find that this disk checkout utility runs automatically each time Windows starts. You can schedule it to start it once, or your Windows can decide to schedule its launch. But instead of working only once, it continues to work every time the computer is turned on when Windows is loaded.

Automatic disc check starts each time starting

If the disk check or the CHKDSK program, the tool is embedded in Windows, starts with each download, here are a few things you can try.

1. First of all, let it start completely at all.

2. Now, you need to open the registry editor and go to the next registry key:

HKEY_LOCAL_MACHINE \\ SYSTEM \\ CURRENTCONTROLSET \\ CONTROL \\ SESSION MANAGER

In the right pane, you will see the BootExecute parameter. Here you need to change its value with AutoCheck AUTOCHK * /. On AutoCheck AUTOCHK *

3. Open the command prompt in Windows, and enter the following command and press ENTER:

fSUTIL DIRTY QUERY G:

This team will ask for a disc, and more than likely, she will tell you that he is dirty.

Next, enter the chkntfs / x G command: so as not to check the specific disk (G) for the next reboot. Next, manually reboot the computer, it should not run the CHKDSK program, and delivers you directly to the Windows desktop.

As soon as Windows is fully loaded, enter another CHKDSK / F / R G: command to the command prompt. This command should go through five stages of scanning and install which bit "dirty". Finally, enter the FSUTIL DIRTY QUERY G command: and press ENTER. Windows will confirm that this disc is clean.

You can run CHKDSK / R or CHKDSK / F commands from the command line to check the hard disk for errors. But if you entered the CKDSK / R and CHKDSK / F command, then it may take a lot of time on your computer with Windows 10.8.7.

Hope this decision will help you!

You article You will find the CHKDSK Using Guide, links to programs that allow you to comprehensively test hard drive, as well as instructions for them. In addition, the article describes how to check the partitions of the hard disk using the built-in Windows.

Windows Disc Checking Utility (CHKDSK)

Windows has its own disc check utility. It can be run from the graphical interface or from the command line.

Run a disc check from the graphical interface

Open the window My computer, Right-click on the disk or partition you want to check, and select from the context menu item Properties. In the disk properties window, go to the tab. Service and click Perform check.

In the next window, click Running.

Checking the unwatching section will begin immediately. If you check system partition Windows 7, you can see a message that now it is impossible to perform it.

This is normal because the system partition is used by the operating system. Press the button Disc check schedule. To start the scan, you need to restart the computer. After rebooting the computer, the disk check will be executed before the operating system is started.

Run a disc check from the command line

Below is an example of running a check check. C. From the command line.

CHKDSK C: / F / R

Note. The command line must be launched with administrator rights.

In Windows 7, as in the case of checking the system partition from the graphical interface, after executing this command, you will see a message about the impossibility of checking.

Enter Y. And restart the computer to start checking.

Additional information about the command line parameters utility chkdsk. You can get by running it with the key /? or on this page.

Run a disc check if the system is not loaded

If the operating system is not loaded due to disk errors, the disk check can be performed using the Windows installation disk.

Windows 7, 8.1, 10

1. Load to the recovery environment and open the command prompt (instructions for Windows 8 and Newer, Windows 7)
2. In the command prompt, enter the command chkdsk c: / r

Windows XP.

If the problem occurred in Windows XP, use the Recovery Console. Uploaded from the installation disk to the console, execute the command

CHKDSK C: / R

For more information about the recovery console you will find in Microsoft Knowledge Base Articles:

• Installing and using Recovery Console in Windows XP
• Enabling automatic administrator entry into the system when using the recovery console

Diagnostics of hard disk by third-party programs

If after checking the hard disk utility chkdsk. You continue to have critical errors related to the equipment, it is worth it to produce more thorough testing through specialized programs. As a rule, hard disk manufacturers utilities are used for diagnostics, or programs such as Victoria.or MHDD..

ATTENSE! Before testing a hard disk using third-party programs, you must back up all data.

Hard disk manufacturers utilities

Diagnostic utilities can be on the CD included in the package of hard disk. In any case, they can be downloaded from the hard disk manufacturer. Links to the download pages of some manufacturers are given below.

• Western Digital.: Data LifeGuard Tools (you need to select a disk model).
• Seagate.: Seatools.
• Hitachi.: DRIVE FITNESS TEST.
• Samsung: SHDIAG.

Diagnostic tools from other manufacturers can be found on their sites.

Victoria.

Program Victoria.Designed for deep testing of the hard disk state, you can find on this link on the HDD-911.com website.

• Excerpts from official Victoria hard disk test documentation

MHDD.

The MHDD program is also capable of comprehensively test hard drive and correct errors on it. You can download it at this link from the site MHDD.ru.

For more information, see the following links:

Disk in perfect order - what's next?

If the errors on the hard disk are not detected, it is most likely not the cause of critical errors. It is possible that the problem lies in faulty RAM or the power supply has insufficient power to ensure the operation of all devices. You can check the prompt memory and drivers as described in the following links below.

You can mark interesting text fragments that will be available on a unique link in the browser address bar.

And SMART information is able to track Windows 7. She will warn you if that.

aASS.

Vadim Sterkin., Thanks for the answer and over the topic!
With the evaluation of Victoria and MHDD programs, I agree, I use Victoria myself for serious diagnostics, but I try to test other programs, everything is in comparison.)

Dmitriy

when checking the hard disk, the standard program on Windows 7 is written that bad clusters are found in null.sys ... What is this driver?

Dmitriy

Vadim Sterkin.,

thank you ... because of it can brake?

Sanya

Hello.
Launched (hypothetically) Disk check with: from a graphical interface with parameters similar to your screen. Pressed the "Disc Check Schedule" button. Changed his mind How to cancel this disposable system disk check before rebooting the system?
I myself assume that it is possible to entered in the task scheduler. " But I want to know for sure. I do not see the point of experiment. Since, after such a check was completed, it was successful (in practical reality), it would be listed in the "scheduler" even as a one-time, and should have been preserved in the idea. After all, the tasks from the "Planner" do not have properties to sense (I think so). But no trace in the "scheduler" did not find. In the internet and on the forum, as you yourself probably know, I have not received the answer.

Simply put, I want to know where this mythical "check schedule" is located and what methods and methods of Seventh Windows offers to adjust it. And it turns out so - click, and ala-ulya ...

Sanya

Yeah…
There was a graphic, and all came out. This is already a graphy of some kind of black and white, with the registry. Straight "Barnight Potemkin".
(Yes, I google, but truth is a little different request). Thank you.
It turns out to be planned - two checkboxes poke in the chart, and cancel - we climb into the registry. They namurried here. Well, okay, nothing to do - accomplish your goal in the forum.

Yes, by the way, and the second (bottom) checkbox makes sense to put if the SSD system? After all, as much as my knowledge is enough, the SSD controller itself is periodically (if simple) scans the memory for faulty cells.
And this second daw, by definition is intended to check the broken cells on the HDD surface.

Sanya

Sanya,

You include your TV with a remote control and exhibit an awakening timer. The next morning you wake up for the music of your favorite music canal. And life flows smoothly and measured. But at one fine moment you are autumn - because tomorrow is Sunday. Do not trouble - tell you yourself. Light movement of the hand and dye, without turning off the TV from the network, you remove the back cover, quickly replace a pair of resistance on the board and is ready. Tomorrow you can sleep peacefully to lunch.
Feel what I mean?

Vadim Sterkin.: San, what does it mean? You do not wise yourself, pressing all sorts of incomprehensible buttons, and everything will be fine :)

It's really funny, but of course, of course truth.
Yes, just not entirely to the place. I do not see anything unpredictable and completely incomprehensible in checking the disk. And the conversation was that if you had a graphical opportunity to schedule such a task, then be kind to provide the same opportunity to disabling it, and not after one place (registry). Either remove schedule when planning (make planning only via CMD), or lay the ability to disconnect this task using the graphical interface. As an engineer, in its technical practice and in the practice of the interface of various industrial programs and IT, I encounter this for the first time. Yes, and in Windows OS also.
That's what I wanted to convey when I said - "Namudrili".
Faced with the question, noticed that this function causes complaints from the user, in terms of frequent independent launches. But we will not. As not related to the topic.
And so, of course, thanks for the comments. Everything is clear to me here.

Regarding the bottom daw:

To perform a thorough disc check, select the "Check and Restore Damaged Sectors" option. In this mode, the scanning program is trying to find and correct physical errors on the hard disk, for which it may be necessary to need much more time.

About the file system does not say anything. Rather about physical disabilities. Some of us are wrong. Or I did not understand something.
And then in the text:

To check and file and physical errors, select both parameters: automatically correct system errors and check and restore damaged sectors.

Comment please. I want clarity in the question.
Whatever you press "all sorts of incomprehensible buttons", and everything was fine. :-)

Vyacheslav

I am very surprising for checking and restoring a disk under Windows 8. Changing the size of the section upwards using the Acronis Disk Director 11 program completed with errors. I wanted to increase the size of the system disk due to a blank place on a nearby section of 200 GB. As a result, this program reports that everything is OK, and the size of the disk in the conductor did not change. I performed the test of the disk tools - it was said that there are errors and need to restart. After rebooting, nothing has changed and the requirement has appeared to restart for correction. As you can guess, it also did not help again. As a result, we have lost 200 GB despite the fact that Acronis says everything is OK, and the system is not able to correct the errors found. Sorrow. Format it is necessary?

Vyacheslav

Vadim Sterkin.,

Actually, under Windows 7, a similar operation was always performed without problems. I always perform the task of expansion / narrowing the partition in 2 stages: First, cut off a piece of space from the seminent partition and translate it into the status "unblocked space" from the desired end of the section, and then we are already expanding another section due to this space (I will perform everything manually in 2 reboots In the case of "jambs", because Acronis is very strangely performing a group of operations. There is a sad experience under Windows XP). So, if under Windows 7 after checking the disk, everything was normalized and free space did not disappear so simple, then under Windows 8 Acronis, the first stage was successful, and when fulfilling the second, broke down with errors, although then reports that "everything is fine". The problem in the end solved the loading with the Live CD from Acronis. It is a pity that under Windows 8 it is impossible to do this. And I was so calculated to the "Improved check and correct file system errors in the media". Of course, it is very difficult to believe that checking and background diagnostics of FS problems, works correctly. It is very confused by the fact that the time to check the same section under Windows 7 and under Windows 8 differs to orders for the better for the latter. Does all the problems are so easy and quickly fixed? Maybe most of them Windows 8 simply does not notice or even worse - ignite?

Well, what option is available in Windows 8 to expand the size of the section? I saw the "Disk Management" snap. Well, I did not see how it can be "standard tools" to cut the size of a logical volume from the desired end. There is also impossible to move the partition within the unimpressed space. If there is an analog that I missed, tell me. In the course, you did not quite well understand that I had under the phrase "the sad experience was under Windows XP." And it was like this: after the reboot, this operation was performed and the electricity was cut down at that moment. Thus, I lost 2 sections, although, in theory, it could be 3 options: the second section would have lost, from which the place was taken due to the incomplete operation of the movement of the NTFS service zones, or only the system partition would be lost (although it is unlikely) or both partitions It would be okay, and between them - some area of \u200b\u200bunimpressed space. But I was very "lucky." We will lower the topic of uninterruptible power sources and it turns out that Acronis is a respected company, and their products are sometimes dangerous to somehow use in the absence of alternatives from the OS. And then another "surprise" floated. And then even with the power supply is all right. But as I have already noted - the last problem was solved by loading with Live CD from Acronis and classically checking the disc, and not super-pool from Windows 8, the advantages of which I have not felt. She, as it were,, but no sense. Or I did not use the disk check tool. Such "optimization" for me is still unfortunately, more questions and distrust than answers.

Conducted a diagnostics of a Windows hard disk (chkdsk). There were no messages, but after it turned out that there is no free space. Although the check was filled less than 50% of the disk. And now it is occupied by 931 GB. Is that all the free prostanity broken was? Disk half a year.

I forgot to say after that I checked Victoria and reported that even no errors.

I do not have the case. It's not about the system disk. And about the external drive. Already found out - the system all the free space marked like trouble blocks. Now I try to figure out this failed or the screw ordered a long time to live.

Vadim, I have such a problem: after starting the CKDSK utility checks, if both "checkboxes are installed, asks to run a reboot and checks, I don't know how to call it, but looks like MS-DOS - quickly run rows on a black background. After the next reboot, I watch information in Windows magazines - an application, text in English, "Many letters", but the meaning can be understood from a single sentence: "Windows Has Checked The File System and Found No Problems". At the same time, several lines above me kindly reported that, they say, "Cleaning Up 31 Unused Security Descriptors". Sometimes not "31 UNUSED Security Descriptors", and more or, on the contrary, less. That is, something is still not entirely fine, and the program is a little bit correct. Type In general, everything is fine, but the bug died. So, how much I run this chkdsk, so much requires a reboot to correct these errors, nothing else is detected. Previously, on another machine in Windows XP, it was rarely happening, and now it is over time.
SSD drive, busy about a quarter. The legal Windows 7 x64 Professional system is automatically updated. If you do not start checking the disk, then there is no reason for anxiety, everything works fine, it is not buggy, it will not fail. So there is a question with this - maybe it is not necessary to spoil my mood. On the Microsoft website solutions to the problem of these errors, the file system did not find, and whether it is errors?

Are there any methods to check the power supply power adequacy? And can due to its insufficient power in games hang / errors?
