Error windows was unable to complete the format
I experienced the same problem (my USB device ). try these steps:
1. Start, Control Panel,
2. Performance and Maintenance,
3. Administrative Tools,
4. Computer Management,
5. Disk Management,
6. Find the USB drive (usually the last storage device before the optical drive),
7. Click on the USB drive,
8. Right click on it and you will see the options (New Partition or Format)
9. Follow the instruction (I chose FAT32), but please do NOT chose Quick Format.
