Q. How can I mark my USB storage devices as read-only?

A. Windows XP Service Pack 2 (SP2) introduces a new registry subkey that lets you mark USB-based storage devices such as memory sticks as read-only devices. This is a useful security capability that can prevent users from copying data from their systems and taking that data offsite via a USB device. To enable the USB write protection, perform the following steps:

Start the registry editor (regedit.exe).
Navigate to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies subkey. (Create the StorageDevicePolicies subkey if it doesn't already exist.)
From the Edit menu, select New, DWORD Value.
Type the name WriteProtect and press Enter.
Double-click the new value and set it to 1. Click OK.
Close the registry editor.
Restart the computer.

To disable this change, you can either set WriteProtect to 0 or delete it.

Very useful tip, especially for out high security areas.

Could this be applied as an administrative template in active directory and if so what would be the scripting/coding?

Can this be applied using AD group policy?

MPASupport--we've passed your question along to John.

In the meantime....we just ran an article by Alex K. Angelopoulos that involves scripting that might be informative: “Controlling Removable Storage Access: Configuration for Vista and pre-Vista systems” at http://windowsitpro.com/article/articleid/98485/controlling-removable-storage-access.html

Also, I saw a Microsoft article you might want to check out: “Step-By-Step Guide to Controlling Device Installation and Usage with Group Policy”

@MPASupport....and any others who were curious--John created a new FAQ that details how to use Group Policy to make a USB drive read-only.
