Oops! Changed my Time Machine backup HD name; now it isn't recognized

[jason.siegel]

Oops! I changed my Time Machine backup hard drive's name, and then noticed in Time Machine preferences that it was displayed as an additional available disk for backup. So I switched the name back, and it's still not recognized as the same disk. When I attempted to back up, TM said its disk was not available?

How can I fix this?

Also, is it possible to change the drive's name without messing up TM?

Hmm. After restarting, TM is able to recognize the drive again. However, I'm unable to change the drive's name now. When I attempt to change it by hitting Enter, nothing happens. Any thoughts?

Thanks.
