Backup and Restore idiocy

For some reason, my backup and restore process now asks me for a
username/password to get to the USB drive I have been using over the
months I've had Vista (Home Premium SP2). I am the only user, and I
have been able to back up to this drive for quite a while. Now, I keep
failing "logon" to my own drive.

Can someone shed some light on this?
