Most of those problems were solved with firmware upgrades to the drives. Kathy, have you tried duplicating any of the files? If I get files that won't copy and I can't duplicate, I generally conclude the file is corrupted (fits with the error message you're getting -it can't read the file). If one of the files is on an internal drive, disconnect everything from the Firewire ports and try duplicating the file on the same drive. That will eliminate any "Firewire issues". I would next boot the computer from your OS X install disk, and run Disk Utility, focusing on one drive at a time -starting first from your startup drive (or whichever drive you're trying to copy from). In the "First Aid" pane, Repair the disk, then Repair Disk Permissions. If none of the files you want to copy are on the startup drive, you'll want to do one of the Firewire drives too. Then restart the computer with all Firewire drives disconnected and try duplicating the file on the same "repaired" disk. If possible (again assuming one of the files is on your boot drive), I might even go so far as to create a new user and move the file and change permissions so you could try duplicating it from the new "clean" account. If this now works with your startup drive (being optimistic) then you can plug in one Firewire drive, start up Disk Utility from your /Applications/Utilities folder, and do the Repair and Repair Permissions on that drive and test it out. As a last resort you could try something like DiskWarrior, but the error message and behavior indicate to me the files are corrupted. Good Luck! -Mike
