formatted extra HDD. now CDROm and burner not recognized

***I posted this in technical support, but got no responses that worked. I posted it here to get some more coverage.


The other day I formatted (using fdisk from DOS) my extra 8Gb HDD. I had no sensitive files on it, strictly data. I deleted all the partitions, deleted the drive, then formatted it in FAT32. When I rebooted my computer, my CDROM and CD burner weren't recognized in explorer. When I went to device manager, they had the exclamation points next to the devices, and I received the error code:

This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)


I uninstalled and reinstalled the drivers a hundred times - they both use Windows standard drivers. I updated Windows (SP3 and all). I tried unplugging the extra HDD to see if that made some sort of difference (it has been sensed perfectly by windows, no problems there) - it didn't. I'm at a complete loss. Does anybody have any suggestions? Thanks!!


Here's an update:

I talked to a hardware guru friend of mine, and these were his suggestions: for some reason the drive letters might have gotten screwed up because I essentially made one partition out of two. He suggested I go into system manager, and check up on the drive letters and all.

So the CDROM (SCSI) and burner (IDE) are shown in device manager, but they don't show up in the system manager under the optical drives section. Does this help any troubleshooters? Is there a way to reset/change all my drive letters?

this is quite a pressing problem (I don't have a CDROM as of now), so any help would be greatly appreciated
 
try renaming these 2 registry keys so that windows builds new values for them & rebooting.

You will most likely have to reinstall any CD recording software after doing this, and the initial situation may be caused by a conflict between CD software packages (i.e. DLA and DirectCD are incompatible with each other and will cause what you are seeing):

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}\LowerFilters

OMG! thank you so much!! It's funny though, I searched through the Windows website for error #31 and got nothing. Thanks again so much!
