Write protect your USB/Thumb/Pen Drive

This trick works only on XP SP2 and you need to have administrator privileges.

  • Open Registry Editor by Start > Run.
  • Type in regedit.
  • Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
    usb_write_protect_1
  • Locate the sub-key StorageDevicePolicies. If it doesn’t exist then create it first. Create a new key under Control by right clicking on it so that you don’t create it elsewhere by mistake (as shown in the above screenshot).
    usb_write_protect_2
  • Right click in the blank area of the sub key you just created and create a new DWORD value by the name WriteProtect.

usb_write_protect_3

  • Double-click it and set the value data as 1 (and 0 for disabling it).
    usb_write_protect_4
  • Click OK, close the Registry Editor and restart the PC.
