I have been experiencing problems with drives on my pc for a while now, with drives appearing in the bios and not in xp, new hard drive appearing to have wiped itselfd only to reappear perfectly fine a couple of days later and not being able to have more than 2 ide devices connected at the same time.
I figured that i may have damaged the motherboard when i had attached a new heatsink and fan and so replaced the mobo. I also changed the ide cables but the problems remain.
All four devices work, but only two can be used, either as master and slave on one channel or masters on both.
Anyone got any ideas what may be going on and how to fix it?
The above motherboard is capable of supporting up to 4 ide drives, I have this board and have
1. Hard drive as Master on IDE1
2. CDRom as Slave on IDE1
3. DVD/CDRW Combi drive as Master on IDE2
If you cannot get more than two drives, have you checked Device Manager for conflicts, or tried updating the sis Hard drive controller.
have you set the jumpers on your drives correctly, if you still have problems, try removing the jumper from the drives (one by one) and see if this helps, or try using the CS(cable select) for all drives.
you say you may have damaged the board, was that the old screwdriver slipped scenario (stupid way to have to fit a Heatsink & Fan), scared me to death doing that. If your screwdriver slipped then you could have damaged the board. doubt it though because you say you can get both drives on as Master or Slave (i think its a jumper problem this one).
Possible solution is to flash the bios, But only as a last resort (doing it wrong can kill your board), try removing the hard drive controller in device manager, restart your computer and let it re-install the controller.
if you are going to flash the bios be very carefull that you get the right file from ECS Website, there are lots to choose from.
be certain about which revision your board is (1.0 or 3.0), it should be stamped on the board (by the pci slots if i remember correctly)
