Tenthirty, Are you using raid feature?
If you are not and if you are using the promise controller try putting it on the chipset ide. I have an A7V that has promise controller non raid. A couple of months back I installed a new video card and a couple weeks later I started having some lockups and various Bsod occasionally power off. Power off happened probobly 10 times in the 6 months before card install. Well anyhow it took me quite a while to find out the promise chip quit. When I tried to restore my setup off of the cd it said I didn't have a drive connected on the promise controller.
I am running 98Se and 2000. 98 shows the device is working properly but I can install the drivers for promise but shows it isn't working properly. I tried various combinations of installing both os's and drive channel combos and the only way I could get this thing up was to leave all of the drives off of promise controller.
if you are using raid you might be able to save it by installing a raid card and connecting your drives to it. If you know someone with a raid you may want to borrow it to make sure that is it before you shell out the jack.

Don't forget regular promise cards can be easily hacked to raid. That is if you are good at soldering.
I thought your problem sounded similar in your other thread. I would lay odds on it now. That is if you are using the promise controller.
