Many computer users get caught with their pants down when their hard disk breaks. A failing hard disk doesn’t always give ample warning to the user before it stops working properly, when it goes, it often takes the user’s data with it.

We keep a lot of precious data on our hard drives, from irreplaceable family photos to critical business and financial documents. This spells bad news for the data you had on your computer’s hard drive or your external drive or flash drive. A common Hard Drive Not Detected error message in which an external hard drive (drive letter H:\) is no longer accessible. In essence, the drive ceases to function properly. Additionally, you might encounter this error when connecting your external drive or removable drive, only to be met with a Windows dialog box requesting you to “initialize” or “format” the disk before utilizing it.


This can include a hard drive remaining invisible in places where it should be accessible, such as Windows failing to display the drive in ‘This PC.’ The problem may also emerge when starting your Windows 10 desktop or laptop computer, resulting in a “boot device missing” error message within the system setup. A hard drive not showing up or hard drive not detected issue can present itself in various ways.
