USB Drive is unrecognized in Mac OS X

I had this problem specifically with Mac OS X 10.3. A series of thumb drives were not being recognized by the Finder or Disk Utility.

The fix was quite simple.

  1. Remove thumbdrive.
  2. Insert a USB device that does work – keyboard/mouse, wireless adapter, audio card, etc.
  3. Insert thumbdrive. In a few seconds, the drive will mount or you’ll receive a format prompt.
