I attached the 2T backup drive in August of 2011. It's only ever been used on my MacPro dual quad. The MacPro is the only backup file on the disk. The main drive that gets backed up is a 2T with 77GB free. It's been working fine for 2+ years. > > Given that Time Machine is complaining to you that it suddenly has to make a > 300GB backup, I'm pretty confident it's under the impression that it is doing > an initial backup.
