If you're a smart computer user and BIOS is what you get into everyday, then disabling or locking USB Drive, sure, is not a big deal. But if you want the whole process to go well from registry, the following is the complete idiot's guide (with the complete downloadable hack) for Write Protecting USB Drives (both ON and OFF).
o Using this function, prevent the write to USB devices.
o This function is only available if you are using Windows XP SP2, I'm unsure of the other Windows OSes.
o Action is immediate without need to reboot or log off the system.
How to disable WRITE PROTECTION for USB Devices?
>> Navigate to this KEY
>> Create or Change DWORD called WriteProtect assigning the value 1 (ENABLES Write Protection) – the value 0 DISABLES Write Protection.
Enable USB Storage Devices
>> Navigate to this key
>> Create or Change DWORD called Start assigning the value 4 (Hexadecimal) (ENABLES Write Protection) – the value 3 (Hex) ENABLES the USB Storage Devices.
Now your USB Device is no more READ-ONLY.
