I ran disk repair from disk utlitity (only checking as you cannot perform repair on the start-up drive) since I had some froze-up with iPod restore with my 15" Al PB. I found 2 errors which says 2 illegal names. So, out of curiosity, I check desk for my iBook and 12" PP and 15" Ti PB as well. Interestingly, iBook and 12" PB also had the exact error messages (2 illegal names). Ti was in good shape. So, repaired those disks via the target mode. Wasn't it odd 3 Macs had the same errrors?
