I can't say what the current status is. But some time ago some people I know got burnt with silent corruption from using HPT cards with RAID5 and RAID0, the cards were replaced with Promise cards, and the problem went away (as it should - I've been running a lot of RAID on Promise cards and never saw the problem).
As long as there are Promise cards to get, I'm not going anywhere near HPT.
Maybe there's a fix somewhere, maybe there's a magic BIOS setting or upgrade, maybe something else can make it work, I don't know. Promise cards are cheap so I don't care.
Sorry for not being able to give you "good" information, but at least now you got "some" information. Hope it helps, for what it's worth.
