DVD-rw installed , now DVD-rom is missing!

[listeruk]

I have a DVD-ROM (D:) drive and a CD-RW (E:) drive.

I have just upgraded my CD-RW (E:) drive to a new DVD-RW drive.

I followed the instructions (removed the old CD-RW, and attached the new drive - put the cables in the same place) - the DVD-ROM (D:/)was at no point disconnected!

When I rebooted, there is only one drive listed (beside the floppy and Local drive), the New DVD-RW, which has taken the drive letter D:.

The E: drive is gone. and the DVD-ROM is no longer to be found.

There is power going to the DVD-ROM (the drawer opens etc) and I have checked that the cable is connected.

I shut down and removed the cable to the DVD-RW drive and rebooted and the DVD-ROM drive is back - as the D: drive.

How can I have the DVD-Rom drive and DVD-RW drive both working like I had the DVD-Rom & the CD-RW?

Any Ideas, Please? Thanks![/b]

Double-check the jumpers on both drives to make sure you don't have them set to the same thing (i.e. one should be master, one should be slave). Make sure they both show up in BIOS. If your DVD-ROM was your (D drive, then it was most like the Secondary Master, and your CD-RW was your Secondary Slave(E. Most (not all) burners should be set to Master, and yours probably was set that way at the factory.

This definitely sounds like a jumper pins configuration issue.
However, If you check the jumpers, and they are correctly oriented, the next step would be to replace the IDE cable.

on face value it sounds like both jumpers were set to the same thing.

Set the jumper to what the jumper on the cd writer was set to.

Another thing is what computer & OS is this? Many computers remember what was in the machine beforehand & if you put in new stuff, it thinks the old stuff is still in your machine. So it thinks its got a cd writer still. Only a bios nvram clearing can change that.
