Have a 1gb external drive connected locally to my iMac via FW800. Latest backup was about 2 hours ago and, though nothing big has changed (other than a couple of Word files), it now says there's not enough space to do a backup. TM is showing 177 of 999 GB available (and I'm only backing up appx a half TB of data). It's as if I'm trying to backup a new machine to an old TM backup file. Also the 'verify backups' is greyed out when option-clicking TM - but I believe that's because it's connected locally (correct?). At this point do I wipe the drive and begin a brand new backup?
