I was trying something similar but without success due to the following
reasons:
1) The 8 IBM drives IC35L060AVER07-0 (made in thailand, march 2001)
where in fact unusable for what I planned to do. Six of them started to
produce 'bad sectors' whithin two days of operation. Using the IBM Drive
Fittness Test tool 'repaired' the disk but new errors came after some
more hours of activity. It was even so bad that the RAID5 never synced
because it always reached a bad sector while syncing. I will send all of
the disks back to IBM but I'm not sure for what - to receive another 8
failing disks?
2) The Promise Ultra ATA 100TX2 has produced corrupt data in two
Computers from DELL. One was Precision 220, the other PowerEdge 1400SC.
This error occured only when accessing more than one disk simultaneously
- be it on the onboard IDE controller or the Promise. It looks like we
have a general problem here because the same was reported from VIA based
motherboards.
However, I'm using the Ultra ATA 100TX2 in my home server with four
Quantum Fireball 15G on a AMD-K6-2 and it work absolutely stable!
My advice is that you just check whether the Promise is stable in your
system and you make sure the 8 drives are okay. Performance of the
Promise controllers is very good.
