I had hoped for a relatively short answer, but if it's
got to be... ;-)

Well, some people here at the office meanwhile told me
that they think (!= know) that the protocol is translated
transparently, i.e. the bridge chip doesn't even need to
know about disk size etc., so no trouble there apparently.

I guess I'll just have to order things in a shop where, just
in case, I can exchange the disk or enclosure.

While I'm at it - what's the current status regarding hard
disks (large IDE drives, i.e. >> 120GB) - which are ok, which
are not? The criteria are mainly reliability, speed isn't as
important for this application.

Over the years, it seems about everybody had bad series
of drives:
- Seagate "sie geht oder sie geht nicht"
- Quantum - the fireballs of 2-3GB did get broken easily
- IBM can't remember the exact series that was bad
- ...
How about Maxtor, Samsung, Western Digital, etc. etc.?

i.e. I'm perfectly willing to buy Seagate again if their
current series are ok.

Greetings & TIA, Eric
