Hello all! I have regularly been using TM with my Leopard. I just wiped my MBP clean and installed Snow Leopard. I have done a manual restore of all the files I need. My question is, can I use the old TM hard drive as the new TM backup drive, without losing the old backups? In other words, if I plug in the old TM drive and designate it as a backup disk, would my old backups be removed? Thanks!
