Fixing Administrator has prohibited access to USB/1394 mass storage devices

by on November 4, 2009

Q: I have an Acer Power computer with Acer empowering technology framework running Windows XP Pro. When I start the computer up I get a message that says “Administrator has prohibited access to USB/1394 mass storage devices”. How do I fix this?

A: There have been many reports over the last few years of the “administrator has prohibited access to USB 1394 mass storage device” error message on Acer computers. It seems the problem is related to software called LanScope. There does not seem to be a logical way to access LanScope to actually unlock the drives so the only way to resolve this that we have been able to find is to uninstall Acer LanScope.

To uninstall LanScope go to “Control Panel” then select “Add/Remove Programs”. From here you will want to find “AcerLanscope” and “Acer-eLock” and have them removed. Then just reboot your computer and try accessing your disks. This should resolve your problems.
