Vista - Restore operation does not see backup folder on logical drive

I just did a backup using the Backup Wizard but cannot find it when I click
Restore - I backed up the C drive to drive K which is a logical drive. I
went to drive K to make sure all the compressed zip bakups are there. Also,
the status says backup was successful and lists Backup (K as the location.
When I click Restore, and choose "latest backup" it doesn't list anything
but when I choose "Files from an older backup" it lists the backup location
as K: but when I click Next, there is nothing to select. And when I do a
search or click 'Add folders', it doesn't list the K drive or any of the
other logical drives when I click Computer. All it has is the C: drive. The
screen before it did highlight the backup on the K drive, so it's really
strange why it doesn't have any selections on the next screen or why it
can't find any drive besides C.
