In any version of Windows from XP onwards, run Regedit.exe (searching regedit will usually show the program at the top of the list).
Navigate to the following key:

Double-click on the WriteProtect value in the right-hand pane of Regedit.exe. Change the Value data from 1 to 0 and click OK to save the change. Close Regedit and restart your computer. Connect your USB drive again, and you should find it is no longer write protected.

When do you get that I/O device error? It sounds more like it can't read it rather than write to it.

Do other flash drives work OK?

Have you tried the flash drive on another computer as it might be faulty?

Always pop back and let us know the outcome - thanks
