Hello I have an abit av8 mobo with one IDE HD and a sata. I have winxp with sp2 on the IDE HD. I use to use my sata drive as storage until one night when I turned my computer off for the first time in a couple days. I rebooted and it wasen't appearing in device manager or disk manage. It is formatted, it does spin, it is not seen by the bios either. I have had this problem in the past getting my computer to see the drive. My powersupply has always powered this drive fine it is 450ws i think. I am completely baffled by this. My bios is a pheonix award bios v6.00p6
There is a screen that is hard to catch during boot up after the post screen that talks about my sata raid rom. This says no devices are attached. I don't know how to access my sata raid rom. But I have it disabled in the bios because I have successful in getting windows to see the driver before. I have the IDE prefetch mode disabled too. I have installed all the latest drivers from via. My chipset is the VIA K8T800 Pro/VT8237. I have installed the latest 4in1 drivers and sata controllers. I have uninstalled and reinstalled the drivers several times to try to get the computer to see it and tried older versions. I cannot get the computer to recognize the driver. I have tried the sata1 and 2 slots no difference.
Please remember I have an winxp on an old 30gig IDE that works fine. And I am just trying to get my stand alone sata storage drive back up and running. It has all my saved information on it.

please assist me in my efforts I have yet to find answer to this. Thanks
