Please give a look at the manual here


Dvdrw internal and external will not recognize dvd - ff68fb6.jpg

Page 17 will tell you what type of CD and DVD you can use.

If you are trying to use a DVD-RW or DVD-R it will not work and it will produce the descibed effect.


Can you please try with a DVD+R and see if it works? If it doesn't work with a + means that the optical drive has some problem and need to be replaced.


Let me know if you need more help.

The Optical Disc does not recognize the Disc, that is, the Optical Disc does not rotate, but it receives power. I tried to run a disc under BIOS setup screen and the same happened

The best bet is to get an external DVD drive from Wal Mart for about $30 or more and forget the hassle. The cost to replace the internal drive is more than it is worth.

My DVD Rom wont open

You can get the DVD out by putting a pin into the little hold on the other side of the eject button. Try putting an audio CD into the drive and see if it recognizes it. If it won't see anything and there's no light, it's probably broken and time for a trip to the computer repair shop of your choice.

PD CD-RW 24x1040 external usb2 firmware

This device is meant only for CDs. However, the drive is an internal CDRW with IDE interface. You can substitute some DVDRW drives, but some DVD drives are picky about voltage and amperage. This enclosure is on the weak side for most DVDRW drives. You'll want to find a DVDRW that can work on as low as 8VDC on the 12VDC line. And the drive can't draw any more than .75A on the 12VDC line either. If the drive requires higher amounts, yor system may only recognize the drive as being connected to your system, but it'll never have the power to read the disc, and just kick it out after spinning the disc around for a short time.

My Lite On DVDRW will not recognize any audio cd's...

Hi PhxROcker,

In these drives there are two lasers and two pick-up sensors. Normally in a combined head. One set is used for the DVD and the other is used for the CD. From you description it sounds like the optical sensor for the CD laser has expired! When you place a CD into the drive a small amount of information is read by the drive that identifies the disc type, manufacturer, it's status, capacity etc. If the drive cannot read this then it thinks nothing is present.

If you insert a disc does the LED on the front the the unit flash a few times while it spins the disc. Does it do this repeatedly? If it fails to read the disc does the LED stop blinking and the drive no longer spins the disc? If this is the case then your drive may indeed be faulty.

Sorry I could not be of any further assistance.
