Making your USB pen-drive write protected
Today USB drive also known as keychain drive is becoming the most popular removable storage device to move data to different locations. USB drives are available in the market with different features, for example password protected, compatible with all windows versions and extra storage capacity (up to 65 GB).
A common security issue at organizations is how to prevent their workers to write data onto USB drives using their PCs, because a user can easily move confidential data for other location.

If you have windows XP with SP2, then you can disable the writing option to USB drives.
Follow the given steps to disable the USB writing option:-
1. To edit the computer registry, first you should log onto your computer with administrative rights.
First click on Start button and type "Regedit" in Run option.

2. Here locate the location to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l


4. Set its value to "1". But again enable this option set its values "0".

5. Now close the registry editor and restart your computer after any changes to go into effect.
This means the USB is unwritable on my PC isn't it? If so, then its not much of work. Cause it were better if the write protection could be enabled on other pc so no virus could get into. That would have been handy.
