This is a very common problem in Windows XP. All it takes to cure this problem (ie: non-detection) is to follow these brief and concise instructions:

Situation
There is a yellow exclamation mark for CD/DVD drives in Device Manager. The device status in the properties of the driver might indicate an error code, for example 32, 37, or 39.

Solution

To solve the issue, you have to edit the Windows Registry:
Click Start, then Run, type REGEDT32 and click OK.
Locate and then remove the following registry values:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlCl ***{4D36E965-E325-11CE-BFC1-08002BE10318}LowerFilters

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlCl ***{4D36E965-E325-11CE-BFC1-08002BE10318}UpperFilters

Close Registry Editor.
Reboot the system for the changes to take effect.

Note: Some programs are unable to detect the CD/DVD drive after these steps. To solve this, simply re-install the program in question, eg: usually your recording software. Also, in few instances the order in which the programs are (re-)installed can make a difference.

And here's another method that will do this automatically for you if you're afraid to edit the registry manually.
