Return it as defective.

If you ever get this message try running chkdsk first.

on the desktop click start --> run

then in the pop up box type     chkdsk e: \F \X

if running win 7 type command into the search box on the start menu and select the program command.

again in the box that pops up type     chkdsk e: \F \X

where e: is the drive letter assigned to your usb pen

this solves 99.9% of disk protected errors and takes 30 seconds.

An interesting option potter.  Thanks.

I’d like to add this link for an additional option to try.—how-to-fix-write-protected-disks

Even after giving run command as chkdsk /fh, the USB flash drive was not responded for format. Please reply with correct answer.

Before carrying out the fixing process, backup all your items in the pen drive

  • Download “APacer Formatting Utility” on your PC
  • After completing the download, you will see Start.bat file in that folder.
  • Double click this Start.bat file. This will initiate the formatting.
  • Now remove the USB drive and attach it into the PC again.
  • Now type “cmd” on run and then enter
  • The command prompt window will open, type CHKDSK [usb-drive-letter]: /F.
  • The formatting process is done successfully
