SSD drive is not detected when connected: reasons, solution.

HDD drives are gradually disappearing from everyday use by ordinary users, as modern editions of Windows 10, 11 (these OSes are the most common today) work much faster on SSDs. Moreover, the prices of solid-state drives are gradually decreasing, which explains the increased demand for them. But what should you do if your computer doesn't recognize the SSD after connecting it? What could be the cause of this and what actions should the user take?


Main reasons why computer doesn't detect SSD

The most common reasons why an SSD drive is not displayed in "My Computer" are:

  1. The initialization process of the drive is compromised.
  2. The drive is not assigned a letter for display in the system.
  3. The drive is not formatted. Therefore, it is not ready to work with the system.
  4. The drive is marked as "hidden".
  5. The SSD is formatted with a file system that is not supported by Windows.
  6. Incorrect BIOS settings.

Drive not initialized

If the computer doesn't detect the SSD drive, the first thing you need to do is initialize it. By default, this is done automatically, but it may not happen due to security settings or a simple software error. In this case, you need to open the "Disk Management" utility (select "Administration" in the "Control Panel", then "Computer Management", and then the corresponding tab).

In the list of connected drives, select the one that is not displayed in "My Computer" and choose "Initialize" from its context menu. A step-by-step setup wizard for the new drive will appear. You need to select its structure, file system. And after formatting is completed, you can start using it.

Drive not assigned a letter

Windows uses a hierarchical file structure. Therefore, each drive is assigned a letter, which is used as its internal address. It is possible that the system failed to assign it automatically. This needs to be done manually, also through the "Disk Management" utility.

In most cases, Windows 10 doesn't detect SSD when it is connected via USB (i.e., it is an external hard drive).

Drive not formatted

In this case, the drive is displayed normally in "My Computer", but when you try to open it, an error like "Drive not formatted" appears. This usually happens with new SSDs that have never been used before.

How to solve the problem? Format it with the built-in Windows tools. To do this, right-click on the connected SSD in "My Computer" and select "Format". It is recommended to check the "Quick" option and select exFAT as the file system - it is optimized for solid-state drives.

Then click "Start" and wait for the operation to finish. After that, you can use the drive fully.

However, it is not necessary to change the cluster size. Windows will set the optimal value by default. It is only worth reducing it if the user needs to save space on the hard drive, but the peak performance is not crucial.

Drive marked as "hidden"

In Windows, an SSD, just like a folder or file, can be made "hidden". However, the drive can only be hidden using specialized third-party programs, such as MiniTool PartitionWizard. In this case, the drive functions normally but is not displayed in the file manager.

How to resolve the problem? Also with the help of the aforementioned utility. Choose "Restore" from the context menu of the drive.

SSD formatted in an unsupported file system

If the drive was previously connected to a computer running Linux or MacOS, it is possible that it was formatted with a file system that is simply not supported by Windows (such as EXT4, F2FS, and so on). In this case, it needs to be formatted again, but this time with a compatible file system (exFAT, NTFS). The process is described above.

Incorrect BIOS settings

In the BIOS of some computers and laptops, there is an option to choose which connected drives will be initialized and which will be ignored (for security purposes). Therefore, you need to check if the initialization function is enabled by default when a drive is connected. Usually, the relevant option can be found in the "Device Configuration" section.

Sometimes, users also encounter the issue of Windows 7 not detecting the SSD. In this case, you need to check not only the BIOS settings but also the presence of a driver for the connected drive. Yes, some drives require driver installation for proper operation (otherwise, the controller will not be initialized correctly, and the drive will not be visible anywhere). Whether a specific drive requires a driver should be clarified directly with the manufacturer.

In conclusion, there can be several reasons why a computer may not recognize an SSD. The most common one, according to user reviews, is that the drive is simply not formatted. It is recommended to perform formatting with the built-in Windows utility, as it automatically adjusts the optimal parameters for the drive.
