I have also tried plugging them into different ide channels on the mobo but still the same problem persists.
I have also tried using an external rewriter using a USB cable (mainly to see if I could at least get the external rewriter to work). This isn't appearing to be ''recognised'' by the pc. When I use the ''add hardware'' thru the control panel it lists the external rewriter in the ''installed hardware'' but this too has the yellow exclamation mark next to it!
Everything else on the computer appears to be working fine. I haven't installed any other hardware at all prior to the rewriters stopping working.
PLease help somebody
