The largest disk in the GEIN:: node (of the "Deathrow" cluster),
$3$DQB1: (DISK$GEIN_DATA), appears to be a ~120 GB Seagate(?) disk.

GEIN:: is a DS10L though, not a DS10.  If the DS10L has the same
or nearly the same on-board controllers (according to some searches
on the internet, it also appears to be an ALi IDE/ATA controller),
then it does seem like it may be so...

I was expecting to get my hands on a DS10 in June, but it didn't went
through so far.  So, I can't say anything out of experience yet.
