1. Solution to Hard drive cannot find or detect CD drive
Make one drive the the Master and the other the Slave, don’t set both to Cable Select.
Is it not recognizing the drives in the BIOS or Windows? Try changing IDE cables?
If BIOS, have you gone into the BIOS and verified that the drives are detected? Try changing the BIOS settings for the IDE Channels from AUTO to CD-ROM. At least then, from a hardware viewpoint, you are forcing the system to recognize.
If machine is not recognizing the drives after a firmware update, then quite possibly could have been a bad flash. Try re-flashing the the firmware.
Try going into Disk Management and verify that there is a drive letter assigned for the ROM.

When you click on the {4D36E965-E325-11CE-BFC1-08002BE10318} ‘folder’ you’ll see an ‘Upper Filter’ & a ‘Lower Filter’ – just click on them & then hit the delete key on your keyboard. I think that mine popped up asking me if I was sure I wanted to do this & I chose yes. Then just restart. It should be back without any hassle. The last time I had this happen I had to go back through the same steps & sure enough one of the filters was back, so I just deleted it again & it my drive has been back ever since!
