DVD Drive is working until windows starts

Recently I connected my HD into other PC then I connected it back on my PC but now I'm having a hard time to make my DVD drive work, I never had problems before and it was working fine.

This is what happens:
When I turn on the PC, the DVD led flashes and everything, I can open and close the tray without problems. The DVD drive is showed in the bios too. But as soon as Windows XP starts loading the DVD drive wont work, with this I mean it wont even open the tray. Once Windows has started its the same...

It looks like the drive is detected because under device manager it shows this: "DVD-ROM SCSI CdRom device", and my other CD drive is listed too. But when I try to access DVD drive, I get a "Please insert a disk into drive E:" eventho I already have a disc there. If I try to eject it using windows nothing happens.


This is how I have my connections:
(got primary and secundary IDE enabled in bios)

Primary IDE: Master is my HD
Primary IDE: Slave is CD-ROM Drive

Secundary IDE: Master is DVD drive (the one with problems)
Secundary IDE: Slave = nothing


Already tried swapping the DVD-Drive to primary IDE as slave but it happens exactly the same.

Im so confused, why would it work before windows starts to load, but wont work after?? What do you recommend me to do? Im out of ideas, do you think its the drive jumpers? Or something related to Windows? should I reinstall?

Moving your drive to another machine has screwed up the underlying hardware profile.

I assume the drive shows up in device manager and my computer ok?
Right click on the drive and click eject... will it eject that way? If so, something has locked the drive.

I would uninstall the dvd rom from device manager in safe mode. Shut down and disconnect the drive physically. Now start up the computer and install the chipset drivers for your motherboard. Reboot and check operation is good with the cd drive. Now shut down and reconnect the dvd drive, but don't let it boot into windows, go straight into bios and set ESCD or NVRAM to enable. This will force a re-evaluation of the hardware at bios and windows should take notice.

Check you have the bios option for ESCD or NVRAM before you start, if not, then you will have to opt to reset the bios defaults instead. Check you have noted the settings before you do this though!

Thanks NooNoo!
Nope, it doesnt show under device manager nor my computer.. the SCSI device that was listed was a virtual drive.

I think I found what the problem is, I was checking dvd jumper when I realized my DVD drive is missing 1 pin (pin #21, *picture below). After reinstalling Windows, device manager detects everything but my DVD drive, so I decided to leave the current configuration (IDE cables, jumpers, bios settings, etc) and swap the DVD drive for an old CD drive that I have, I kept everything the SAME, guess what? it worked fine, device manager detected my old CD drive with no problems.
What I found strange is, when I formatted and reinstalled windows I made it using the DVD drive that has 1 pin missing! and everything went Ok until windows started, then the DVD drive stopped working again. Remember I told you it worked just fine until windows started... Its just like when windows starts you cut the power off the DVD drive, it wont open, flash or anything.

My question is, ¿Can 1 pin cause that Windows isnt able to detect or use the drive, but that my bios is still able to detect and use the drive (before windows starts)?

See this picture - there should be one blank - it provides a key so that the cable can't be put in the wrong way round... but you have two!

What the missing pin does, I don't know because I have never looked up the pin assignments... but it's reasonable to assume that the missing pin is the problem.

Thanks for your help, really appreciated :)
