Mac does not see an external disk. IMAC does not see (does not define and does not find) hard disk. MacBook does not see the SSD section

Mac computer - This is a rather complicated device in which high-tech "iron" is combined, and software from various manufacturers. Such a variety leads to the fact that when faults occurs, it is difficult to determine what exactly the problem is in programs, equipment, or in their interaction.

Most modern computers are running different versions Windows, and component manufacturers develop their products, focusing, first of all, on them. At the same time, Apple products comes with an operating room mAC system OS, developed by company specialists. Manufacturers of computer "iron" try to give their products a proper level of universality, thanks to which Mac or MacBook, in most cases, will be able to work with the same components as computers running windows, but sometimes lining occur. Often there is a problem at which Mac does not see hDD - external or internal, which is quite unpleasant, especially if there is some kind of carrier an important file. In such a situation, it is important to determine the source of the problem. It may be:

File system mismatch;
Incorrect connection;
Physical breakdown of media information.

What to do if the poppy does not see an external hard drive

Trying to understand why the poppy does not see outdoor hard Disk, you should pay attention - a new USB drive, or old. In the absolute majority of cases, the file standard of the drive is incompatible with Mac OS. Operating system Apple uses the HFS + file system, while most external disks, HDD, and SSD initially work with nTFS systemcharacteristic of windows. To the Mac OS system saw new Disc - It must be formatted accordingly - otherwise, the drive will work with restrictions, or not to work at all. For formatting, you can use the built-in "disk utility" Mac OS. This method also helps solve problems with connecting internal hard drives. This utility opens by pressing the Command + R keys when loading the system. If the MAC disk utility does not see the hard disk - check the connection, in the case of an external drive - try using another cable.

Try to use another cable makes sense if Mac stopped seeing an external hard drive, which before that worked fine. If such problems occur, experts advise you to connect another hard drive to the same computer, and check whether it works. This method helps to determine whether the disk drive has failed, or the breakdown occurred inside the device housing. Try turning out others external devices - Perhaps they interfere with power supply to the outer hard drive. If the poppy stopped seeing the hard drive - check it through " disk utility", And run the recovery process. This method It will help if the device has software properties.

When to contact the service center

Not all problems with computer equipment The user is able to diagnose one, at home - the user should have a certain experience, and access to specific equipment. Hard disk can stop connecting as a result of damage to its structure, or malfunction motherboard - In this case, there is a risk of loss of data stored on disk, or a complete output of a computer. If formatting, checking the connection, and other basic methods did not help correct the problem - better contact the specialists, and take the poppy to repair.

Turning to us, the client will be able to call the wizard home - when ordering repairs in the MasterSoft service center, the departure of the master within Moscow is free.

In recent years, MacBook - Apple products have gained unprecedented popularity. But any digital technique ever breaks. This fate did not bypace the "apple" devices.

If you judge on statistics, many problems arise with a hard drive computer. It will reasonably notice that such a problem occurs not only from Apple products. How is it shown?

The user, working for MacBook, faces the fact that the device is touching. Trying to restore performance, the user restarts the computer. But in response, the computer is not loaded, and the monitor is painted with white flowers, on top of which a folder appears with a flashing question mark inside.

After having a simple diagnosis, you can come to the conclusion that MacBook does not see the hard drive. Such malfunctions need to be eliminated as quickly as possible, otherwise the problem will become much more serious. The delay will lead to excess, unreasonable repair costs. The stronger you contact the service center, the more likely to fix the computer.

The reasons for MacBook does not recognize the hard drive several:

factory marriage (the device at the very beginning of operation ceases to work);
wear (breakage happens after a long time limit);
overheating (the normal rhythm of the auxiliary mechanisms is disturbed, and if more specifically, the cooler is not cooled to cool the macuke filling);
mechanical damage;
moisture getting
operating system errors.

Each of them is detected by the specialists of the service center and is corrected.

Identify problems and repair.

Starting its activities, a specialist for repairing digital equipment conducts full hardware and software diagnostics. This will determine what the problem is. If it's about the OS, drivers, settings, incorrect programming programs, the wizards will eliminate the problems or update the software.

Then, when there is a hardware malfunction, the housing is opened, after which the item is studied for the subject of repair. When such it is impossible to replace it.

Replacing a loop.

Very often, MacBook does not see HDD because of a riginal loop. Then there is no need to fully change the drive. It is enough to replace the broken element. Specialists cope with such a breakdown in a short time. For this they have everything required tools, and experience without which you can not do. After all the required procedures, your SSD will start functioning again.

Fair, not overpriced and not understated. The service site should have prices. Be sure! Without "stars", it is clear and in detail, where it is technically possible - the most accurate, final.

Let's figure it out for reason why your MacBook does not see the SSD disk when installing the system, or after installation and during operation.

This article is suitable for all models. MacBook Pro. And AIRs manufactured in different years. There may be some differences in architecture or description mAC version OS.

Primary disc adjustment

To work with SSD, it is necessary to format it into the file system that the device supports: APFS, EXFAT or HFS +. The new APFS file system is excellent for using built-in solid-state drives, but converting external SSD. and hard disks in this format Causes certain problems that we consider below.

Specify your question by a specialist

Do not know how to solve the problem in the work of your gadget and need a specialist advice?

MacBook does not see the SSD section

If the SSD section does not appear in the Finder window or on the desktop, and the "disk utility" the drive recognizes, then the problem is in formatting. The disk convert to one of the supported file systems can only be used when using the "disk utility".

Increase

By running the utility, you must select the volume of the necessary SSD drive, and then click on the top of the screen to the "Erase" button and specify in the "Format" section of the supported file system. We need to choose EXFAT or Mac OS Extended (this is HFS +, most users can use the option without encryption and register).

In Time Machine is not visible

When the MacBook Pro gives an error or does not see SSD during attempt, then the problem may be the file system compatibility. In a situation with Time Machine, everything is a bit more complicated: although MacOS supports fully operation with EXFAT format, a regular utility for reserve copy Functions only with new APFS or with HFS +.

Use the Time Machine section must be exclusively. If you do not want the whole drive to occupy backups, then you need to divide it into two or more sections. One sections should be formatted in HFS +.

Other disk utility errors

Some SSD users based on APFS are challenges. The system refuses to create for external hard disk Image image or format this section. This problem leads to the fact that many third-party applications Backup can no longer work with the section, at the time of creating an image issuing an error.

Increase

Only developers are able to solve the problem, releasing the "Pack" for their applications. Therefore, you can simply not use APFS for external drives.

Compatibility and hardware problems

Problems with peripheral devices in most cases have hardware roots, and they are associated with the functioning of the system interfaces. For example, if MacBook Air. Or MacBook Pro does not see SSD, which is connected via the ThunderBolt / USB adapter. This problem may be in the housing or cable connector. Defect connector for a long time can pass without a trace.

Mechanical problems are not the only source Problems. MacBook may not see SSD, which is connected through an adapter due to an incompatible interface standard. This implies:

Early MacBook does not support new models and M.2 PCIE drives.
Late laptops do not support earlier storage models, M.2 SATA and MSATA.

The problem is complicated by the fact that adapters and storage devices of standard devices under M.2 (the most promising standard for Apple owners) can be performed in PCIE- and SATA execution, which significantly complicates the choice of compatible components. It turns out if the connector is compatible with the connector of the adapter used (on M.2 unified connector), the application of another standard will not allow the system to determine the system.

Increase

The only way to decide this problem There will be an acquisition of a storage compatible with your laptop. For MacBook Air and Pro until 2013 and for early MacBook Pro Retina. 2012 - 2013, you need to choose discs that support SATA. More modern computers Support discs on the PCIE base. You can also use an external adapter that will allow an incompatible drive to apply as a portable storage.

High Sierra does not see SSD disk

High Sierra has many changes: built-in support for programs for virtual reality, New file storage architecture, recycled the "Photo" section. The main innovation was the support of NMVE technology.

NVM Express is a special specification on access to quick SSD discs that are connected by tire PCI Express. In the name "NVM" means high-dependent memory, in the form of which the NAND flash memory is used.

This logical interface is created for minimum delays and effective use of high SSD parallelism due to the new set of commands and methods of processing queues optimized for functioning with multi-core modern processors. In this situation, PCIe discs with a M.2 connector (NGFF) will be more interesting, as they can be used in the modern Apple technique.

The screenshot below shows the advantages. new technology On Kingston SHPM2280P2 / 480G disc drives, Samsung 960 EVO MZ-V6E250BW (NVME). Testing on MacBook Pro Retina 13 "made in 2015.

Increase

During the installation of the disk to a laptop, a thermoskotch, it is necessary to wind up the adapter and SSD disk compound, as in the screenshot below.

Increase

Before the start of the physical installation of the ready-made disk (adapter, SSD, the winding of the thermoskusch), you need to do with Mac OS High Sierra bootable USB flash drive and install High Sierra to the device. It is performed to have the opportunity to new system Move all files.

Move information on a new system with a new SSD disk is carried out through Time Capsule.. If it is not, you can install the backup to the removable backup drive and you can restore all data through Time Machine.

After the physical installation of the disc booting with boot flash drive. You need to run the terminal, then register the Diskutil Mountdisk Disk0 command. This is done in a situation if there is no discs at the current disk in the device.

In other situations, you should register disk1. Then open the disk utility, in the left upper corner We deploy all the information using the "View" button. Now you choose "show all devices", after which the unimpressed SSD Samsung NVME disk will be displayed. It must be formatted, then install the Mac OS High Sierra on it and return the information via Time Machine, Time Capulse or use the net system.

In practice, problems occur when leaving sleep. This is solved in the terminal by the "Sudo Pmset -a Hibernatemode 25" command. With this command, the dream data is sent not to memory, but in SSD.

At the speed of the output or sending to sleep, this team does not affect any. If the disk is still not defined, then you need to lose sMC Settings.

Tips on using SSD drives on MacBook

It is important to know about the proper preparation and configuration of the SSD system. Consider a number of tips that will help to work comfortably with the drive.

Turn on Trim

SSD drives are inclined to litter, which deteriorates performance. The problem is solved using TRIM technology. It is on Mac, which are completed with SSD discs, activated by default.

If you performed the upgrade yourself, then turn on the Trim manually. To do this, terminal is applied, but it is safer and easier to use free utility Chameleon SSD Optimizer.

Increase

The application needs to unlock access by entering system Password and activate the Trim switch. Then the laptop will reboot, and you will not need the program anymore.

In the settings of the utility, you can disable hibernation, Sudden Motion Sensor sensor and establish a ban on creating a dump random access memory. These functions can extend the drive time.

Customize work with NTFS

While working with external drives, users have to deal with file system NTFS. In OS X, you can read files in NTFS, but add new or change them will not work. To this, it is better to prepare in advance so that Mac will not refuse to function normally with such a drive.

Free place

To disk SSD. Not turned into a garbage, it is required to clean regularly. All dubious folders can be deleted manually, but it is better to use specialized applications.

Increase

For this will suit the DaisyDisk program. If quick and advanced cleaning is required, you can use Clean My Mac 3. Application Functions:

Removing systemic garbage.
Demonstration big files.
From other programs removes unnecessary locations.
Cleaning the system from unnecessary additions.

Connecting cloud storage

If there is not enough SSD volume, then come to the rescue cloud storage. All popular services have a separate client for OS X, where there is the possibility of selective synchronization.

Synchronization at all can be disabled, and download data only on remote server, deleting from the device. You can send those files in the cloud to which you need more often. If necessary, they can always be downloaded back.

Folder "Downloads"

This directory most often takes place on drive SSD.. It is necessary to disassemble the downloaded regularly and lay everything on the right places in the cloud or external drives. You can still instruct the Automator application.
