A tip from Paul Mather pointed to problems with USB/firewire chipset,

Can you provide these details (forward what Paul sent you, etc.)? It
would be nice to have this info somewhere in the archives in case
someone mails about similar...

Here it is;

I don't have your original posting, so I don't know what model of
chipset you have, though I do dimly recall it being a Prolific, which is
why I thought I'd e-mail you. Given that the PL3507 had an early
history of problems when writing to it using large transfers (and that
GELI uses large transfers, IIRC), and you say that enclosure is old, you
might want to see if chipset bugs are the source of your problem.

Here is a link I had bookmarked when I was looking for firmware updates for
the Prolific PL3507:

Here is a link to the corruption issue that plagued various chipsets,
including the Prolific PL3507:
