> unable to read any CD or DVD. Its detected in device manager but cant ready media.
Can you hear it "spinning" the media? If not, you have a "defective" unit (motors or bearings).
If it spins, but nothing is read, then you have a "defective" unit (dead laser).
Take it back to where you bought it, and get them to test it, to prove that it is "bad", and then for them to replace it.

> in Hardware details it shows HL-DT-ST DVD RAM GH24NS50 SCSI CDROM Device.
Normal for most SATA devices.
> it shows as HT-DT-ST CD-RW GCE-8526B ATA device.
Perfectly normal.

If the drive is not working then it will need to be replaced. Check to see if the door opens & lights come on after loading a disc. If they do then it is more likely a driver issue. You can try to uninstall the drive in device manager and then reboot to see if Windows identifies the drive and installs the driver. If the drive is dead then replace with a compatible drive. Hope this helps.

Hi there, as per your information the device working well. But not read CDs. So i suggest you install a CD/DVD Reader or rewriter software.
Because, with out the software your DVD/CD device can't able to read CDs. You can use Nero Express software for solving your problem.
Thanks & waiting for your feedback.

have you tried device manager and right clicking to update driver and allowing internet access

One possible source of difficulty is there are different blanks for "slow" recorders (1x - 4x), "high speed" recorders (4x-10x), "ultra speed" recorders (12x-24x), and "ultra speed +" recorders. The disc manufacturers had to change the way the discs were made to accommodate each successive improvement, so older recorders don't work with the newer disks.
It is possible for some 4x-capable "slow" drives to use the "fast" blanks with a firmware upgrade, but there is no advantage to doing so since you're still limited to 4x recording (unless, of course, you're unable to find "slow" CD-RW blanks).
CD-RW discs for the faster drives are labeled with a "High Speed", "Ultra Speed", or "Ultra Speed +" logos. Make sure you buy the right blanks for your drive.

It could be that it needs a lens cleaner or realigning, but try this and see if it cures it, sometimes it works. If it still persists go to my computer>properties>hardware tab>device manager and go down the list to cd/dvd drives, click on the '+' and right click on your listed drive and select uninstall. restart the notebook and then the drive will be re installed with drivers automatically.

it seems that your cd rw burner has reached it's MTBF, or it might have even over lasted it, I myself experienced such problems and the only way to solve it is to replace its read write assembly as a package, it is available at all LG computer peripherials store.
