DVD Drive problem

[Delorean]

I have this NEC DVD Writer Drive. it was working perfectly for about a year now.

A week ago i changed the power supply from a 300W to a 500W.
From the moment i pluged in all the wires evrything were working but the DVD writer.

The real problem is that i can open the DVD, showing that current can pass through it, but when i open My Computer, the DVD is not even beeing detected by the computer. Not even in the Bios:wacko:
Anyone has any ideas what could posibly causing this?

Btw i can't even format it because i fear tha i won't be able to install windows after that!

Check the IDE cable.

Jumpers? What do you mean?
Have you fitted a sweater or pullover?
Sheesh.

Have you tried another IDE cable?

You could also try another power cable. I'll bet your power supply has a few spare.

Another thing comes to mind... Have you tried reconnecting the 300 watt unit to see if the DVD drive works again?

VB i did tried all possible combinations with my power supply's wires.. however, since i can open it, it means that i can get power from power supply.

As for my old Power supply i don't have it anymore.

I haven't changed the jumpers btw, i left them as they were before but... i 'll try to find another DVD and plug it in just to eliminate the chances that is my DVD's fault.

Nevermind guys, problem solved! The ribbon cable was faulty so and the second i used, but a third one made it work!

Thanks for your responses guys!

Is in't that funny it was the cable , last thing I 'd probably check . They do get twisted and turned so may times ,always nice to have a spare . :)
