Some recovery or backup programs that aren’t fully compatible with larger USB drives will shrink the drive’s partition. This makes the drive appear much smaller than its actual capacity.


To restore your PNY flash drive to its full capacity, you can use the Windows DiskPart tool:


  1. Open Command Prompt as Administrator.

  2. Type: diskpart → press Enter.

  3. Type: list disk → press Enter (note the disk number of your USB drive; stop if unsure).

  4. Type: select disk X → press Enter (replace X with your USB drive’s number).

  5. Type: clean → press Enter.

  6. Type: create partition primary → press Enter.

  7. Type: format fs=exfat quick → press Enter.

  8. Type: active → press Enter.

  9. Type: assign → press Enter.

  10. Type: exit → press Enter.




After completing these steps, the USB drive should show its full original capacity again.
