Norton Ghost 15 Destination Disk name change

I have been a Norton Ghost user for many years, through all its incarnations, and it has been a lifesaver more than once.

My current problem is very minor, but none the less annoying for that.

When running a backup, the destination disk is shown as a removable hard drive that I no longer use. The drive letter is correct, and the backups work fine, but Status says that the drive is "not available" even though everything works. Is there a way that I can point Ghost towards the correct drive name?
