Chkdsk On External Drive Fix

If CHKDSK cannot fix the drive, or reports it is in RAW format, you may need to use advanced disk management tools.

Ensure the physical lock switch on the drive (if any) is off, or clear the read-only attribute via diskpart . chkdsk on external drive fix

Type Y (Yes) and press Enter . Restart your computer with the external drive plugged in. Windows will run the scan before launching the desktop. Ensure the physical lock switch on the drive

"CHKDSK is not available for RAW drives"This occurs when the file system is so badly corrupted that Windows can no longer recognize it as NTFS or exFAT. In this case, CHKDSK cannot help. You may need to use data recovery software to pull your files off before reformatting the drive.
