Seagate Barracudas are NOT recommended. Can you do a "smartctl -x" and
see if SCT/ERC is supported? I haven't got a datasheet for the 1GB
version, but I've got the 3GB version and it doesn't support it. That
means you WILL suffer from the timeout problem ...

(Not that that's your problem here, but there's no point tempting fate.
I know Seagate say "suitable for desktop raid", but the experts on this
list wouldn't agree ...)

Cheers,
Wol
