My 6 month old MAxtor One touch Turbo 600GB HD died yesterday. Disk utility says this: Checking HFS Plus volume. Invalid B-tree node size Volume check failed. Error: The underlying task reported failure on exit (-9972) Repair attempted on 1 volume 0 HFS volumes repaired 1 volume could not be repaired I need to recover some info, please help. Can i run fsck over the external HD? What app would do the trick?
