ok, #1- The previous owner bought the Tiger download from apple and D/L'ed it, so I have no disk, only the panther disk it came with. Is there a way I can save the OS incase of rapture and I have to completely reload it? (I know, chances are slim, but would be nice to be prepared.) #2- I have the garage band CD's here and only one of 4 loaded. They look fake to me, but I know the information is on there. The others say "cannot mount disk" Is there any way to open the files and extract the information to add the loops, instruments, etc? If there a safe way to force it to mount? Thanks all!
