I echo Greg Lehey's lack of problems with a 2940UW and an Exabyte 8505
(non-XL for me). Specifically relating to termination, though, I had to
change the Exabyte from an external wide connection to an internal narrow
connection, because I already had a CD-ROM drive on the internal narrow
connector and two WD Enterprise drives on the internal wide connector, and
the 2940UW does not support the use of all three connectors at once.
Repeat: only two of the three connections can be used at once, and
termination should be properly configured for the types of connections
used.
(Now if I only know what "Sending SDTR!!" meant on boot for the WD
drives...)
A bug in my MUA causes news.announce.newusers font
to be sent to beneficiaries and senders of UCE/SPAM. @
