Media issues are probably the easiest to solve, so we will start with those:

• There is no disk in the drive.

• If recording, a blank disk may not be in the recordable CD drive.

• Disk is upside down.

• Incorrect kind of disk e.g. 8X speed disk in a 48X burner.

• The CD/DVD drive writer may be incompatible with media produced by certain companies.

• The disks may be too old.

• The disk may be defective.

• For CDRs and DVDRs, the disc may be "open." Before you can use the disc in computers that do not have the recording software installed, the disc must be made ready ("closed" or "finalized.

• Perhaps corrupt files found on burnt disks files were corrupt before the making of the disk.
   

Relevant possible power issues affecting CD/DVD drives:

• Power cable is defective.

• Power cable is loose.

• Power supply is partly defective or dying.
  
   

Hardware reason for a malfunctioning CD/DVD drive:

• Drive is dead.

• Drive is dusty.

• Drive laser lens is dirty.

• Drive door is jammed shut.

• Drive motor is dead or the drive train is out of order.

• There are two drives on an IDE cable and they are both set to "Master" or both are set to "Slave".

• There are two drives on an IDE cable and both are set to "cable select", however the IDE cable is a regular not "cable select" type cable.

• Data cable is defective.
  

• Data cable is loose.

• The drive is not on HCL (Hardware Compatibility List) for the version of Window used.

• Motherboard is partly defective or dying.
   

These causes for CD/DVD drive problems, could be see as either hardware or software issues depending on circumstances and your point of view:

• The PC has not been restarted in too long.

• The BIOS needs updating.

• A previous drive has been manually configured in the BIOS so the configurations are now wrong.

• The firmware of the drive needs updating.
  

• You may be using a Samsung CD-RW Drive that has issues.
  

• Failure to successfully create an Audio CD with a Hewlett-Packard CD-Writer drive may result from firmware issues.
  

• The CD/DVD device driver is not designed for the IDE controller to which the drive is attached.
  

• The IDE CD or DVD drive is not ATAPI 1.2-compliant and the only driver available for the IDE controller to which the device is attached, is the XP default one.
  

• Devices plugged into video outlets are interfering with the CD/DVD drive, player software or burning software.
  

• For DVD playback, many video adapters help decode DVD discs. However, the video adapter may not fully decode a DVD movie, so you may need a hardware or software decoder for your DVD playing.
   

Possible software issues for why a CD/DVD drive is not reading or burning, are the most numerous. They are in no particular order except alphabetically by the first letter of the first word of the sentence:

• A SCSI CD/DVD drive has been incorrectly installed or the SCSI controller is not on the HCL list.
  

• Another program may be using the recordable CD drive.
  

• At least SP1 has not been installed yet if you have Windows XP.
  

• Data transfer channel is on PIO but should be on DMA or the reverse.
  

• For CDR-s and DVD-Rs, the disc may be "open." Before you can use the disc in computers that do not have the recording software installed, the disc must be made ready ("closed" or "finalized.
  

• If burning, certain versions of Roxio products are simply not compatible with Windows XP.
  

• If burning, older version of Adaptec CD creator and Roxio EZCreator need to be updated.
  

• If burning, playing or burning software has become incompatible with a Windows or BIOS update.
  

• If burning, the "Use this device for recording" check box is not marked in the properties of the drive.
  

• If burning, the burning speed of the drive is set too high causing buffering errors called "buffering underuns."
  

• If burning, the computer does not have enough free space to make the disk image in preparation for burning.
  

• If burning, the hard disk is too fragmented.
  

• If burning, the IMAPI CD-Burning COM Service is not started or is corrupt.
  

• If you are burning, the simulation feature of Nero is turned on but needs to be turned off.
  

• If you use Windows internal CD/DVD burning. capabilities, the service may be corrupt, not compatible with your drive.
  

• Perhaps corrupt files found on burnt disks files were corrupt before the making of the disk.
  

• Some of the NeoMagic video adapter drivers are not fully compatible with Windows XP, causing poor audio playback.
  

• Sony’s Rootkit is installed on the machine.
  

• The burning or CD/DVD player software needs updating
  

• The c:\windows\inf\cdrom.inf file is missing or corrupt.
  

• The drive is misidentified in the registry as the wrong kind of drive.
  

• The drive, secondary ID or secondary SATA channel needs to be uninstalled and reinstalled in Device Manager.
