KT7-A RAID - don't bother with RAID-1

I can report that after days and days of attempts with every method I could
conceive of RAID-1 refuses to work correctly under Win2k Pro or Server.

For the record my system consists of:

KT7A-RAID MB
1.2 (266) T-bird
256 Crucial CAS-2 PC-133
Two Maxtor DiamondMax 60 ATA-100, 40GB
ATi Radeon VE
bios YH w/ HP 1.03b1

All in Antec case w/ 400W PS

No other cards at install

Sampling of methods attempted:

Create mirror on IDE 3 as master and slave, install Win2k (install would
never complete)

Same a

Install on single attached IDE3 master, let Win2k create partition(s) and
format. Then add second drive as IDE4 master and create mirror. This was
most successful and almost had me fooled into thinking it would work until
Win2k "forgot" where the partition records were and gave all kinds of crazy
errors.

Yes, I not only created the mirror, but I also copied from source drive to
target as per instructions.

Seems to me that the HP-370 driver just doesn't work with Win2k (other
versions I can't speak to) in a Raid-1 config. I've resorted to using
mirroring within Windows and paying the performance penalty.

The onle option I didn't try that has some potential is to create one single
partition the size of the drive. Since I really didn't want one giant root
drive, I created a 10gb root every time. I tried creating the second
logical drive various ways, but it seemed to have no affect.

You need at least 3 drives to create a Raid 1 setup.You create a stripe set
and then mirror it to a drive equivalent in size to the stripe set (40GB in
your case) or you use four drives and create two stripe sets (Raid 0) and
then mirror the first to the second.

I sure hope you are kidding and don't really think it should work like that.

Actually I was describing a Raid 0+1 setup, sorry. I didn't read carefully
enough.
