I just picked up a dual 1.25 MDD to replace my slow dual 450

None the less, I've spent the last few hours fighting a problem
transferring data from my old drive (80gb WD ata/100), to a
Deskstar 80gb ata/100, and I figured it would be best to ask the
experts (you guys). The drive that originally came with the
computer (Seagate 80gb ata/100) stopped working while transferring
data (now it's not recognized by any computer), and the Deskstar
has corruption issues now. The drives are set up using the ata/100
bus, both drives set to CS. The computer works great, but somewhere
between the two drives when transferring data, everything gets
messed up. The original drives data seems fine, and it passes the
utility tests, as where the Deskstar now shows errors, and has
files I transfered that can't be opened (and a lot of them). Did I
screw up somewhere, or could this be a computer problem? I'm open
to all suggestions, and I really appreciate the help. Thanks
I ran into something similar recently. First thing is you might try
putting the "other" drive on the third ATA bus. Until I got the
MDD I didn't know it has 3 ATA busses.
The other thing is the drive that came with it was, I think, an
80Gb Deskstar. While it worked fine in the MDD, it won't work in a
Sawtooth (I had a 160 Gb HD from the Sawtooth I use in the MDD
now). Of two Firewire drives I've tested it in only one would see
it properly. I haven't yet investigated it, it might be a matter of
the ATA version.
I CCC'd the 160 Gb over to the 80Gb, reformatted the 160 and copied
everything back. I had tried doing it with the two drives on the
same bus, that had problems recognizing the drives. I tried putting
the 80Gb in a FW enclosure and that didn't work. About then I
noticed the 3rd bus, tried that and that worked just fine.
The third Bus in the MDD is ata 33 for the optical drive I think that
it's too slow for a HDD that's used for anything other than
storage.
The optical bus is ATA-3 but I'm not talking about that one. The MDD
also has "1 - Ultra ATA/66 (ATA-5), 1- ATA / 100 (ATA-6)" per
MacTracker. I'm talking about the ATA/66 bus.
In any event be it 33 or 66 it's still just fine for transferring the HD
especially if it avoids the problem the OP is having.
