Thanks for your advice. I did consider eSATA but there's a possible
issue with hot plugging.
I also understand that some controllers have problems with
hot-plugging, and I definitely need hot-plugging ability. Perhaps
there's an eSATA PCI or PCI-e card you can recommend that is known to
have Linux support for hot-plugging?
The host machine already has an unused PCI SATA-1.0 card installed
(this one: http://www.pbtech.co.nz/index.php?item=ADPSTL12360 - can't
find the manufacturer's page) however I strongly suspect it won't
support hot plugging. I can at least try it and see - however I've
never connected anything via eSATA before so I'm not completely sure
whether I can use the 'standard' SATA cables externally (are they
properly shielded?), and how one gets power to the dock?
Would you (or anyone) happen to be able to recommend a good (reliable)
eSATA external "dock"?
