Hi guys,
I have a big problem. My computer cannot detect my dvd or cd drive.
The dvd drive is of samsung and cd drive is of liteon. Its not the power supply because when i press the open button the drive opens. My computer screen appears without any DVD or cd drive icon. Do i have to install driver or something else.  PLEASE HELP!!!!!!!!!!

Check the master/slave jumpers and the cable/power connections...

hi guys;
same problem with me.my computer wont even start with a dvd drive.cd drive is working fine.without dvd computer works normally.wat can be the problem.?it all started when i downloaded new drivers for dvd and re-started my pc

Have you installed any games recently that use StarForce protection? If so, go to their web site and download the starforce remover.

what motherboard?

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.

Have you checked for Virus's, had this happen to me sometime back.  My computer couldn't see the CD drives, damm virus.

I HAVE THE SOLUTION.  
 
This happened to me and i called a dell support guy and he fixed it!!!  
 
This is what you do...
 
Start the Run Command Prompt
 
Type in "regedit" without the parrenthesis then click ok
 
Go to HKEY_LOCAL_MACHINE
 
Then SYSTEM
 
Then CURRENT CONTROL SET
 
Then CONTROL
 
Then CLASS
 
Then find {4D36E965-E325-11CE-BFC1-08002BE10318}
 
The whole thing looks like this:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
 
Then delete the upper and lower filters....
 
RESTART YOUR COMPUTER THEN THERE YA GO!!!! HOPE THIS HELPS

none of these worked for me.go to bios.ide function set up. set channels optical drives on to mode 1. drives  can then be seen in my computer
