RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this behavior, follow these steps:
Start Registry Editor (Regedt32.exe).
Locate the UpperFilters value under the following key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

On the Edit menu, click Delete, and then click OK.
Locate the LowerFilters value under the same key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

On the Edit menu, click Delete, and then click OK.
Quit Registry Editor.NOTE: After you remove the Upperfilters value and the Lowerfilters value, if you notice lost functionality in a particular program, such as CD recording software, you may need to reinstall that software. If the problem recurs, consult with the software vendor for assistance.

Restart your computer.
STATUS
This is a known issue that can occur when you remove Easy CD Creator version 5.01 or earlier or DirectCD version 3.01c or earlier. This issue may also occur with Easy CD Creator version 5.01 and with DirectCD 3.01d or later.
MORE INFORMATION
There may be other third-party CD-writing software products that exhibit similar behavior. Some or all of the troubleshooting steps in this article might apply if such a product also adds entries under the UpperFilters or LowerFilters value in the registry, either by adding its own filter drivers or by removing the registry keys and values outlined in this article that begin with:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Try this simple test to check if your system can locate the cdrom drive.  

1. Secure a windows 98 bootdisk.
2. Insert bootdisk in drive A: then boot up your machine.  Make sure that you had configured cmos to boot on floppy drive first.
3. In the boot menu please select the first option, with cdrom support.
4.  Check if cdrom drive is available.  If not try to check the cables connected to your cdrom drive.

Hope this helps. =)

More information needed here to get a better answer.

in xp, 2000, u need not have sequential drive letters. you can assign different drive letters to drive in any order...so dont worry about the missing drive...

this applies only if the drives were not there in the first place..
you can change the drive letters from the windows disk administrator...

Were D and E CDROM/CDRW? If so, chances are you may have a loose IDE cable, if both connected to the same cable.  Another possiblity could be a conflict with the secondary IDE controller. Depending on the OS you have you can go to the device manager and check out your controllers.
Someitmes CDROM/CDRWs go bad and prevent the detection on one or both units on the cable. You can remove one unit at a time a see if the other detects.
