Windows 7: Changing Drive Letter for USB Ext HD - Parameter is Incorrect

Changing Drive Letter for USB Ext HD - Parameter is Incorrect

Hi Everyone,

I have a few external disk drives I'm accessing via USB. When I attempt to change the drive letter using Disk Management I get a popup window that says: "The Parameter is Incorrect."

These are SATA drives that I previously had assigned drive letters like T, V or X while on a Windows XP computer.

My OS is Windows 7-64 and it currently assigns drive letters automatically.

Any suggestions?
