Just some information.... Most of these external USB and/or external Firewire disks such as ACOM, etc., contain an EIDE (ATA) hard disk plus an adapter board with a USB or IEEE sequencer. These sequencers can be a pain in the ass because they do 8-bit math. It may be necessary to artifically constrain the per-operation data-length with this in mind.
