hi,
just wanted to let you know that your blacklist of
ata-100 drives for HPT3 is most likely overzealous.
as you state you tested it only with 41gb.
I own
IBM's 61gb IC35L060AVER07-0 drive.
ABIT KG7-RAID with HPT370
First I have been running "Linux version 2.4.2-2" RH7.1
and this sets the above setup to ATA-100 and I had not
experienced any problems.
Once I "upgraded" to 2.4.10 my drive got blacklisted and
runs as ata-44.
to double check, I removed the driver from blacklist for
100 and 66 and recompiled kernel, and it seems to be
running fine so far.
now there's weird part, for both drive running at ATA-44 and ATA-100
I get pretty much same numbers from hdparam. Perhaps it just an change to
printf alone, and drive runs at ata-100 even it if says that it is ata-44
? what kind of numbers should I expect from ATA-100 drive anyway?

Some HPT cards have problems with certain drives. I believe its a fixed
problem in newer boards or on those with updatable firmware if you update
the firmware itself
Check your drive is in the bad_ata100_5 and bad_ata66_4 list. If not add
it then rebuild and retry (drivers/ide/hpt366.c) - and let me know

This turned out to be the problem. There is a new generation of IBM Deskstar
drives (that are really nice drives :-) that have the same incompatibility
with the HPT-366 chip as the older IBM drives did. Below is a patch to add
the entire series to the "bad drives" lists, although I personally have only
experienced the problem with the 41G model I think it's logical to assume
they'll all have the same problem.
Drives work fine once this patch is in place, although only in ATA-44 (weird
mode).
