It could be a problem with the lens you could use a liquid type lens cleaner place 2-3 drops on top of a cd/dvd then run it Hope this helps.

If it happens for only one particular disk:
Bring that disk to a game store like Gamestop or Rock30 Games and have them professionally clean the disk for a couple bucks.

If it happens for all disks:
Clean the cd/dvd with a laser lens cleaning kit. If that doesn't fix it then the cd/dvd drive will need to be replaced.

The recovery cd is just a Pre-Built Windows version that includes the drivers you need for your computer.
If you want to format your pc and lack the original recovery cd, you just need to get a Windows (or other operating system you want) installation CD/DVD, put it on your optical drive and reboot your computer.
On installation, you will be asked what you want to do: Fix or Install. Choose install and check to format your disk.
After installation, if something doesn't work, its because you don't have the needed drivers, so go to Dell's Support Page find your computer, download and install the drivers you are lacking (video card graphics, sound, etc.)
Hope it was helpful ;)

Remove the disk-drive from the laptop, and connect it to another computer.
Copy all the files from the recovery-media onto the disk-drive.
Reinstall the disk-drive into your laptop.
Run the recovery software from where you copied the files onto the disk-drive.

try rolling back the driver

Hi Chopadepve,

Please try this method but be more careful during working out on it:

Since your DVD drive reads cd's, but not dvd's It shows that the hardware works fine. Now we need to Edit the Registry to fix this problem.

1) click the start menu
2) click on "run"
3) type "regedit" and click ok
4) go to string key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
5) delete "upper filters" and "lower filters" in the right side window.
6) right click my computer in the start menu.
7) click properties
8) go to the hardware tab
9) click device manager
10) expand the dvd/cdrom drives
11) right click the dvd rom and click uninstall
12) Reboot PC

Windows should automatically install a clean ROM drive after the reboot otherwise Open the device manager window and click "scan for hardware changes". DVDs just read fine if you have the correct DVD decoders.

If no luck then might be DVD read head wiped out.
