DVD Drive disappeared

[Andrew Chalk]

I just added a hard disk to my PC and the DVD drive disappeared from
Windows, although not from the BIOS.

I had

IDE1
-----
Master: Hard Disk
Slave: Hard Disk

IDE2
------
Master: DVD drive

and all was fine.

I changed IDE2 to:
Master: DVD drive
Slave: New hard disk.

The hard disk appears as drive E: under XP, but the DVD drive has
disappeared.

Does anyone have any idea what caused this and how to fix it?

Many thanks

Does the DVD show in disk management?

It may not have a letter assigned.

No it does not.

In general you shouldn't put a hard drive as slave on a secondary
channel with an optical drive as Master.

Any combination of Master/Slave/CS has the same effect. The hard drive
appears but the DVD drive does not.

Does the DVD Drive appear in the BIOS or POST when you first power on
the computer? If it does not show up there, it is a dead DVD Drive.
Also, double check the power and jumpers and cables again to make sure
they are all correctly and snugly connected. Have you recently tried to
flash the firmware of the drive?

When you have a hard disk and a CD or DVD on the same channel, the hard
disk *must* be the master. Change jumper settings over

No it does not.

This happens if a related driver style file, probably from CD burning
software, has gone AWOL. To tidy up, get a registry patch file,
cdgone.reg, from www.aumha.org/downloads/cdgone.zip, extract it, r-click
on it and merge it into the registry and reboot

You will then need to reinstall any burning software that you *do* use.

Found it!

This may be useful to others:

Windows configured the secondary IDE device to use DMA. I set it to use PIO
only and Windows recognized the drive.

Generally, harddisk should be set to master with the optical drives set to
slave.
So in your case have you tried setting it the other way around for your
IDE2? With your hd as Master in IDE2 and the DVD drive
as slave. I also assume that you've set the drives' jumpers correctly. One
as master and the other as slave.
Who knows perhaps you might get that DMA back.
