I have never had a reason to try it on a hard drive, but I would suspect it
is just for floppies. In fact it must be, because hard drives are generally
hard sectored. To effective really wipe the HD you need to do a lowlevel
format. You were or someone was talking about floppies as well.

Make me an offer. I have seen really good external cases on ebay at really
good prices. They also include power supplies. I have seen them go for under
$20 and these are brand new ones. What I intend to do eventually is get an
ATX compatible tower case with a MB slide out panel and use this AT full
tower case for SCSI drives. It can hold up to 3 FH drives internally and I
have 5 exposed 1/2h bays. I could even put a cage it it with the mother
board and put more drives it it. I can currently without modifications put
11 1/2h drives in and and a ton of LP drives in it. I can set it up as a
RAID without buying expensive controllers with Linux software. There is a
Linux HOWTO or mini-HOWTO about doing this. I would like to get several 9GB
SCSI UW drives. They are getting cheap now.

I don't think so, because these were OEM cards and the company I bought it
from created their own manual and they did not sell HVD contorllers. I think
someone inavertently thought the controller would work with all types of
drives currently available at that time. LVD drives were available, but they
can be jumpered to work signle ended and this is probably what they intended
it to mean. I have gotten very good products from them and never had any
other problems. It may have even been in the way the worded it.

Oh! Yes that was an expensive MB. EISA was very good. Slow for today's
standards but great. In fact ALR had a 128 bit wide data buss for some of
their systems and it really screamed even though the buss speed it 8MHz. But
all the info could travel on different data paths at the same time. ALR made
some really great stuff. They also made some junk in their lower performance
systems.
I can only use ID 0 and 1 for boot on this card. I can disable the BIOS in
it, so it would make a good second card for slower rate drives like my CD
ROM and Syquest and tape drives. The problem is the number of slots we have
to work with<g>.

This controller has a non-volatile rAM for setup. I don't even have to
manually change jumpers.

No, this is the Mother Board BIOS that I was talking about. I should have
made that a little more clear. It an Award BIOS and has no turn off option
for it. That is what I was complaining about when I said pinhead software
writers that have no clue about the real world. I have not found a utility
for Award like AMI has to go in and change thing in CMOS that is not in the
CMOS menu. Else I could probably force it off. I don't need it for my card
anyway. My card detects this mother board BIOS and let's it take over the
boot process. The nice thing about it is non memory is used for ROM in UMB.
