Odd DVD-ROM problem

#1

Alright, I will soon become angry. I have a major DVD-ROM problem : it reads intermittently. Sometimes it works, sometimes it won’t.

Sometimes the BIOS recognizes it, others it doesn’t, and others still it recognizes it but then says “secondary master drive fails”. That’s bad.

I have tried :
A) A different drive (a CD-ROM drive, actually)
B) 3 different IDE cables, 2 40-pin and one 80-pin
4) Flashing the BIOS
5) Flashing the firmware
6) Underclocking the CPU and unplugging just about everything I could to save some power.

I suspect it’s either the mobo’s IDE controller or the PSU. I use Linux, by the way, so don’t suggest Windows apps :wink:

Thanks,

Sony DDU1621. The test CD-ROM drive was a CDU4821, which otherwise works perfectly.

Maybe your power supply is not pushing out enough power,check in your m/b bios

Try switching it to the other ide channel and see what happens.
