help please... i finally made the jump to panther. backed up my data in 10.2.8 on a pioneer A05 on a couple of DVD-RW's. trouble is.. one disc seems to have an area of damage(?) where it doesn't want to copy the data back to my hard drive in 10.3.3. it says 115 hours of copy time for a small amount of info. other areas on the disc copy over fine. anyway to get it repaired? f.y.i. the disc previously had data and i went to disk utility and erased it. then used toast to write the data dvd. one thing i tried was to make a copy of the dvd in toast but got an error message midway through ("couldn't complete the last command because there was an I/O error"). this happens to be my wife's data so the emergency is slightly greater.
