So, after successfully resurrecting my old pc by fitting a replacement PSU I decided I would replace the third drive which I had removed to use in my other machine.
After replacing the drive in the resurrected machine I find none of the drives present are recognised. There are two other hard drives and a CD ROM which all work fine until I connect this third drive. The third drive also worked fine in my other machine. The third drive also works fine if I remove the second drive from the resurrected machine and install the third in its place. If I then go on to try installing the second drive on the spare connector everything disappears again.
The primary (boot) drive is on the end connector of one ribbon, the one furthest from the mobo with the second drive being connected to the middle connector on the same ribbon. The CD ROM is connected to the end connector on the second ribbon with the middle connector on this ribbon being the spare onto which I'm trying to connect the third drive. The fact that drives one and two work by themselves suggest to me they are in the correct place so it must be the adding of the third which is causing the problem. All three used to work together just fine but something seems to have changed.
I thought maybe I was mixing 2 and 3 up and connecting them to the opposite connectors and so confusing the machine but I get the same result wherever I connect them. Both drives 2 and 3 work when connected to the middle connector next to drive 1 but connecting the spare drive, be it 2 or 3 to the last spare connector on the 2nd ribbon causes all the others to disappear.
Is it possible that running the machine with only the two drives has disabled the third and I need to re enable it somewhere? I have messed around with this for ages trying to figure out what is going on and tried googling and searching on here but have been unable to find any solution so I'm hoping someone might be able to point me in the right direction.
System details are Windows XP Pro, Pentium 4 1.8 GHZ, Quntumn Designs Limited PLATINIX-2 V1.XX board, 1.25GB RAM, Boot drive is SAMSUNG SV1021D 10.2 GB, other drives are Maxtor diamondmax plus 9 80GB ATA/133, WDC WD400EB-00CPF0 40.02 GB. All jumpers are in the same positions they were before this problem started.
Thanks for reading. Hope you can help.
