Symptoms and Causes

It is possible that Windows informs you that there is a problem with the internal hard drive, external hard disk, USB flash drive or SD card, and asks you to run scanning and repairing for the drive:

"There's a problem with this drive. Scan the drive now and fix it."

"Error Checking (USB Drive (F:))
Repair this drive
We found errors on this drive. To prevent data loss, repair this drive now.
Repair drive
You won't be able to use the drive while Windows finds and repairs any errors. This might take while, and you might need to restart your computer."

"Do you want to scan and fix removable disk (F:)?
There might be a problem with some files on this device or disc. This can happen if you remove the device or disc before all files have been written to it.
Scan and fix (recommended): This will prevent future problem when copying files to this device or disc.
Continue without scanning"

Most of us will choose to scan and repair the drive, for we care about the drive as well as files stored on the drive. There are two possible situations after running the repairing process: no errors are found, or Windows cannot repair the drive:

"Error Checking (USB Drive (F:))
You don't need to scan this drive
We haven't found any errors on this drive. You can still scan the drive for errors if you want.
Scan drive
You can keep using the drive during the scan. If errors are found, you can decide if you want to fix them."

"Error Checking (USB Drive (F:))
Your drive was successfully scanned
Windows successfully scanned the drive. No errors were found."

"Error Checking (USB Drive (F:))
There was a problem repairing this drive.
Windows was unable to repairing the drive. Close this dialog box and then try to repair the drive again."

Why does Windows ask to scan and fix the drive? The error can happen due to several factors, for example:

  • The drive involved in the error has bad sectors.
  • The computer gets shut shown abnormally, for example, sudden power failure.
  • The drive was removed from computer unsafely.
  • The drive infects virus or malware.
  • The file system of the damaged drive is corrupted.
  • The drive is not recognized by OS properly.

What to do when Windows was unable to repair the drive? Don't be panic. The message does not mean the drive is beyond repairing. Although Windows scanning and repairing cannot deal with the problem, you can try other solutions to fix it.

Important: It is strongly recommended that data backup or data recovery should be performed as soon as possible when Windows prompts there are problems with the drive. Do not try repairing the error before all files are safely recovered or backed up, because important files stored inside the drive may get lost or damaged during the scanning and repairing process.
