CD-RW Drive not recognised in BIOS

I have just added some extra RAM and a USB2 port to my PC. All appeared to be fine until I noiced that the light on my CD-RW drive was permanently on.

When I boot up, there is an error message, saying that it could not be found and there is no sign of it in My Computer. I can't even eject a disk by pressing the button on the drive.

I have checked the wires (power, parallel and audio) and they all seem to be connected correctly.

Is there any way of testing it, or should I give up and get a new one?

Hi, light permanently on is somtimes an indication that the ide cable is the wrong way round on the back of the drive. I would advise a thorough check again on all connections.

Cheers.

Did you disconnect the CD-RW data cable?

If so, make sure that the cable is correctly positioned. Normally there is a RED tracer down one side of the cable. Make sure this end is attached to Pin 1. Often the cable is "Keyed", so it can't be turned around, but it's just possible.

Have you correctly set up USB in BIOS? There may be a conflict with the CD drive. Make sure USB IRQ is set to auto (or whatever yours is for automatically assigning interrupt requests to USB devices).

I've checked all the cables, and still no success. I'm afraid the USB IRQ in the BIOS menu seemed too complicated for me. I couldn't work out how to change it to auto.

Did you try cursor keys?

Try Page Up/Page Down and +/- keys.

Did you disconnect the CD-RW drive when you carried out the work?

What operating system are you using?

What is the total size of your machines memory?

Is the memory size indicating correctly on the boot-up screen?

Is the data cable keyed?

  JustinJSY 23:55 25 Feb 05

yes, but it didn't seem obvious which was the USB I had just installed. Even if I could work out which one(s) it was, I couldn't see how I could change it to Auto. I was able to change the BIOS to operate the CDRW as auto or indeed turn them off, that was fairly straight forward.

I will buy a new CDrom drive tomorrow and give that a go.

Data cables.
