Also just write protect it
USB drives are extremely handy tools, but in some instances it might not be a good idea to allow users to write onto these devices from their PCs. This is especially true when working with highly confidential data or intellectual property at work. Users of Windows XP with service pack 2 installed can disable writing to USB devices.
To do this:
Open the Registry Editor click on the Start button on your taskbar, then click on Run and type "regedit" and click on OK to start the regedit utility.
Expand HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l.
From there right click and create a new key and name it "StorageDevicePolicies". In the window on the right then create a new DWORD value and label it WriteProtect, give it a value of "1" and users can no longer write to USB drives. To re-enable this option change the value to 0 and users are again allowed to write.
The modifications you made will be in effect after you reboot your PC.

1. Go to Start -> Run -> Type regedit and hit Enter or click on the OK button.
Browse to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l
2. Create a new key called StorageDevicePolicies
Right click on the Control, select New -> Key and type in StorageDevicePolicies
3. Create a DWORD called WriteProtect under StorageDevicePolicies that you created in step 2 and set the value to 1.
This will prevent users from writing to USB drives.
To allow writing to USB drives just change the value to 0. Oh, you donâ??t
need to restart your computer in order to disable write access to removable
storage using the method above.
P/S: When I tried this tip, i couldnâ??t get it to work as I am still able to write and copy files into my USB thumb drive. Finally I found out that when I created the Key and DWORD in regedit, I accidentally added a space at the end of the word/value. After I removed the space which is invisible, it worked perfectly
