I can't remember if I posted the problems I had between the VST 
ATA/66 card and the Apple/Adaptec 2940U2B here or not.  In brief, 
having both installed under OS 9.1 caused all support for HFS+ to 
disappear.  HFS+ volumes wouldn't mount; volumes could not be 
reinitialized as HFS+, etc.  Either card by itself seemed to be okay. 
So I wasn't sure whether to blame the VST or the 2940U2B.

So I was doing some experiments on another machine, and I ran into 
the same problem between the E100 card and the VST card under OS 9.1. 
So, is anyone else out there using an E100, a VST UltraTech/66 and OS 
9.1 in the same machine?  If so, do you have any HFS+ volumes?  Can 
you get them to mount?  This problem only manifests under OS 9.1.  It 
does not occur in OS 8.6 or 8.5.

Now the testing that led to the above discovery was actually not 
related to that at all.  It was my Retrospect problem I mentioned a 
week or two ago.  I can't do a restore from my CDRW drive if the CDRW 
drive is on the internal Fast SCSI bus (Bus 0), but it works fine on 
the external/internal unenhanced SCSI bus (Bus 1).  So I tested this 
on a couple of different motherboards, with different SCSI cables, 
with different devices moved to the end of the chain to provide 
termination, under 9.1 and 8.6, etc. and the problem remained. 
Remove the VST card and it goes away.   In this case it definitely 
isn't the SCSI card, because one machine I tested in had an Adaptec 
2940UW and the other had the E100.   In one machine the drives were 
formatted wiht SoftRAID, in the other with HDTK.

So the only thing in common seems to be the VST card.  So, Retrospect 
users take note.  The VST card seems to make the internal Fast SCSI 
bus unusable for Retrospect operations.  The operation will start but 
only progress a few MB and then just idle.  The little cursor gears 
will spin but no progress will be made.

Retrospect usually has these problems when there's an underlying SCSI 
problem, so I would guess that things like large file transfers or 
transfers or large numbers of files using the internal bus would also 
fail and that MacBench Disk tests might not complete.

At this point I would tentatively say that if you're in the market 
for an ATA card you may wish to avoid the UltraTech/66.  It has great 
ATAPI support (CDROM, DVD drives) but there are a number of 
incompatibilities that keep cropping up that make me think it may be 
more headache than its low price is worth.

I welcome reports of corroborating or contradictory experiences.
