When you say "connect it to my 2 UDBs" I hope you mean one at a time,
as you will obviously have trouble if you connect the drive to two
machines at the same time. (Well I have heard of it being done but
both your UDBs would have the adapter at address 7 and that would
definitely NOT work).
The SCSI HOWTO suggests using good quality cables and also suggests
using an active terminator. I had problems before I got an active
term but my external devices were at least recognized.
I have a 2Gb HP hard drive, a 4Gb Seagate HD, a Conner tape drive,
a Panasonic CDROM and an HP scanner all on my external scsi chain
and they are working fine. I am using the "other" release of Linux
for Alpha but I don't think that would make a difference. In any
case, there is nothing inherent in the hardware that would prevent
your drive working.
In my experience scsi problems are almost always cabling and/or
