Disk Format Testing Method

The test bench for these utilities is a Windows 7 computer with a Kingston DataTraveler DT101 G2 8 GB USB 2.0 drive.


Before each test, the unit has a test file that is raised and the drive is write-protected through the Diskpart tool. The USB drive is then removed from the computer and reinserted. This ensures that the computer is reading the most recent attributes. Skipping this step sometimes results in Windows Explorer not being able to see the drive.

The USB drive attributes are checked in Diskpart and an attempt is made to copy another test file to the USB drive. If the copy fails, then you can safely assume that write protection is working.

The format utility is then run on the test drive. If it ends with a successful screen, then the USB drive is checked in the Windows Explorer to see if the test file is still there. If the test file is gone, the utility is declared to have formatted the USB drive successfully.

To see if formatting eliminates write protection, an attempt is made to copy the test file to the USB drive. If the copy file is successful, write protection has been deleted.
