exFAT Recovery — Fix "Needs to be Formatted" Without Losing Data

When Windows says your external drive "needs to be formatted," your data is almost always fine. The exFAT boot region got corrupted (usually from write caching + unexpected shutdown). This skill walks through diagnosis, repair, and prevention.

When to Use

• External USB drive suddenly says "needs to be formatted"
• Drive shows in Disk Management but filesystem is blank
• chkdsk reports "Corruption was found while examining the boot region"
• Any exFAT drive that won't mount after a crash or reboot

Diagnosis

Step 1: Confirm the drive is recognized
