OK, I have not been able to find an answer to this one. (Also posted on the Apple forums). I had an external FW drive die on me yesterday. No biggie, or so I thought, I back it up with Time Machine. Well, much to my surprise, when I opened TM, the drive was not available in my Finder view to restore from. I thought this was strange, knowing it had been backing up as I check it regularly, and I could see the data if I manually browsed my TM drive. I tested something to make sure I wasn't going nuts. I unplugged another external drive that I backup with TM, and same thing - could not restore from that drive. Plugged it back in, and wala, there it is in the Time Machine window to restore from. Am I just doing something wrong here? Why in the heck would Time Machine NOT allow you to restore from a drive that no longer exists? I mean, isn't the whole purpose of a backup so you can restore in the event of a disaster? I would assume, if I plugged in a new drive and named it the same, it would show, and allow me to restore to it, but what if you want to restore somewhere else? I managed to get around it by simply manually browsing the Time Machine volume, but either this is a serious bug, or a REALLY poorly written piece of software.
