Can't Open USB Drive in Windows: Fix and Recover

If a USB drive appears in Windows but does not open, the cause may be a missing drive letter, file system corruption, access permission issue, malware, or a failing flash drive.

Do Not Format Too Early

• If Windows asks to format the USB drive, cancel it first.
• Try another USB port or another computer.
• Check whether the USB drive appears in Disk Management.
• Recover important files before repair if the drive shows RAW or 0 bytes.

Fix a USB Drive That Will Not Open

1. Open Disk Management and assign a drive letter if none appears.
2. Run chkdsk X: /f only if the USB drive has a recognizable file system.
3. Scan the USB drive with Windows Security.
4. Check permissions if the error says access is denied.
5. If the USB shows RAW, recover files before formatting it.
