The problem description
“My USB drive worked fine all the time except today. There was a pop-up saying the drive needs to be repaired. So I had it scan and repair. However, when I tried that, it failed, and from that moment on, I couldn't access the files within the USB. Every time I try to access this USB drive I get the following error message: Please Insert a Disk into Removable Disk (G:). I’m in panic now, as I can’t access any files in this disk. Any advice to fix it?”
This is a real case from Microsoft community. For USB drives or other removable disks, this is a common issue and usually starts when the computer prompts that your drive needs to be repaired. When it occurs, users cannot utilize the drive and access data within it. If you check its properties, you might find the USB disk shows 0 bytes, or it might report no media in Disk Management.
When it comes to the possible causes of the error “please insert a disk into removable disk”, there are some major reasons you should know.
1. Drive letter conflict. If the disk name (drive letter) is conflicting with another name which is already assigned to other hard drives, then the error may appear.
2. Removable disk is corrupted. Remove the removable disk without safely ejecting will lead to disk corruption and disk detected but inaccessible issue.
3. Bad sectors. If the disk has bad sectors or suffers physical damages, it canalso prevent you from accessing data and pop out the error message.
4. Virus and malware attack.
