It's a common problem among Windows, MacOS and Linus users that a hard drive cannot be detected by the computer. This is a very frustrating situation where you can't access your hard drive. So how can you recover data from the undetected hard drive? Don't worry. In this article, we'll show you several reasons for the issue that the hard disk cannot be detected. Afterward, we'll guide you to recover data from the undetected hard disk step by step.
External hard drive might not be detected in Windows for various reasons and it's a common issue especially aftera system update. Here we list some of the main causes:
USB port or USB cable is broken.
The hard disk has a partition issue.
Virus attack and malware infection.
The hard disk doesn't have a drive letter or the drive letter conflicts with other disks.
The file system of your hard disk is not compatible with the operating system.
You've updated Windows to the newest version, say, Windows 11, and have been experiencing some hiccups.
If the file system of your hard disk is not supported by the operating system, your hard disk will be considered as a RAW disk or RAW drive. The only fix is to format your hard disk to a compatible file system, but you'll lose all your important data. And if there is a partition issue on your hard disk, the disk will be marked as unallocated.
Once your hard drive doesn't show up in your computer, you should first check the USB port and the USB cable. In some cases, the problem can be fixed after changing a USB port or cable. Then you can recover data from it easily. However, in some cases, the hard disk may only show up in the Disk Management instead of the File Explorer. In these circumstances, you may need a professional recovery program to recover data from the hard drive.
