write-protected removable hard drive

After moving a hard-drive from one Server08 box to another, I could no longer write to it.  Instead, Windows gave me an error about write-protection.  I’ve seen this before on a Windows 7 machine, too. 

The error might be result of unresolved user accounts from one machine to another but I’m not certain.  After numerous attempts at changing permissions and taking ownership, I did some research and found this solution which worked:

Start > Run “cmd”
type< diskpart
type< list volume (type< list disk )
type< select volume # (type< select disk #)
type< attributes volume clear readonly (type< attributes disk clear readonly)

When I ran the command, the drive letter changed but I could actually write to it.  Another forum suggested running chkdsk on the drive which I’ll try next time.
