Subject: Re: SCSI connectivity
different
Yes, I liked the 1522A that I had. Never had any
problems
out of it once I upgraded the ROM so that I could use the whole 2gig
of the IBM 0662 hard disk I was trying to plug up to it. I didn't
care much for thier prep/format software under Windows though.
2 gig's??? The two '0662's I have right here are both 1 GB. Are there
models? I've used 'em together with larger
drives but they've always
claimed to
be 1 GB drives, which is what they claimed when they
were new. They are
about
the best 3-1/2" SCSI drives I've used, in that
there's never a problem and
they
always behave just as expected
I like these drives too; they are one of the few scsi drives in which
I know how to set the jumpers so the drive doesn't initiate sync
negotiation; this is important for many computers from the '90 vintage,
as their ROMS did not like the drives initiating the negotiation.
If you think an Adaptec ROM update will help with that,
i.e. making them 2
GB, I
think you'll be disappointed.

I haven't had a lot of experience with other PCI products. I have
a CMD 6520 which works ok, although Linux did not seem to like it.
Nice utilities in the BIOS, such as sector-wise duplication. It also
has a 72 pin SIMM slot for a disk cache as large as 32MB, I think.
I have a RAID controller by IBM in a big Linux box at work.
_Very_ nice. However, the drivers for RedHat 7.0 have not surfaced
yet, so we're running a heavily patched 6.2 .
I have used many adaptec controllers, 1522, 2740, 2842, 3940UWDPI
(dual channel; nice), 2940, 2940U, 2940U2. Never had a real problem
with any of them. Upgrading the BIOS is usually a good idea, though.
