DVD Drives Not Appearing in Windows 7 or Ubuntu 9.04

Hey y'all, I've been having some problems with my DVD drives (one is a rw, and the other is a dl-rw) for a while now. I believe the problems appeared when I got and installed my Radeon HD 4870. I have a 520 W Corsair power supply with plenty of amperage over the 12 V rails, and the drives still have power (they open and close and such).

They just don't appear in Windows 7 (build 7000) or Ubuntu 9.04.

I've already tried wiping my CMOS settings (that's the BIOS) and checking the connections to the drives, and neither have worked. Anyone have any ideas?
 
I know this is kind of a corny suggestion, but did you check your Device Manager? Does it even see the drives in there at all?
 
First, see what you can figure out without getting the OS involved.

Are the drives recognized by the BIOS? You can check this by entering SETUP and doing an AUTO DETECT test for the drive.

If the drive(s) can't be detected by the BIOS, then you still may have a connection problem (bad cable?). Or maybe try to put your old video card back (or use on board video if you've got it) just to see if that changes things with the BIOS. Try a known good drive+cable from another machine and see if you can get the BIOS to recognize those.

If the BIOS does recognize the drive, try booting windows in Safe Mode. If you can see the drives in safe mode, but not on a normal boot, then you've got some kind of windows configuration problem, but I discount that, since you get the same problem in Ubuntu.

Those are some suggestions. Tell us what you tried and what the results were.

I'll have access to a known working drive and the time to try that out (as well as trying my old graphics card) in about a week (after finals).

[quote name='Mr. Anderson']I'm having this same problem with XP right now (after installing my video card), and I found this:

I just tried it, but I'm not super confident in it because the problem also appears in Ubuntu. I'll report back on this whenever I restart my computer (which I hate doing :bomb:).
