I did the same (changed the speed in the BIOS settings) and it's
working. I tried it at 80 but I think I'm going to bump it to 160 and
see if it works.
The 160 speed works as well for me. It seems that only the 320 speed
causes a problem. Which is interesting because Dell says that the drive
should be able to operate at 320 as well.
I remember that the aic79xx driver has a known problem with timing at
U320, but I'm no longer able to find the reference on the web (but that
just a limitation in me finding the proper keywords to search for).
This problem has been there for a long time, at least since OS version 3.0,
but was never resolved. Apparently, it's still there in CentOS5.
(and it's not a CentOS problem, the references I found a couple of years
ago referred to the upstream's version).
The 2TByte limitation is documented for Adaptecs: it does not do the 64-bit
addressing on the SCSI bus, so there moving to LSI is indeed the only option.
