If your drive reads cd's, but not dvd's That indicates that the hardware works fine. You will need to edit the registry inorder 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

Combo DVD burner drives - drives that can read and burn both CDs and DVDs - have at least two lasers and associated circuits. Sometimes one of those malfunctions after the drive has been used a lot. In that case the drive can only read and burn CDs, or can only read and burn DVDs.
That's a lot more common than the situation ganesank123 has pointed to the fix for.

Do you have two DVD drives installed on your computer and you're having problems with both of them ?
You can't have one DVD drive and have both problems, unless your problem is different - you can't read or burn any CDs.

If you have used the prpblem drive(s) a lot, the laser lens(es) may be "dirty". Try using a laser lens cleaner CD in the drive. If you don't have one, you should have one. They are available at most places that sell CDs and DVDs, and even some "dollar" stores have them for a buck or two.

If your only DVD drive, or one of your DVD drives, can't read or burn any CDs, or can't read or burn any DVDs, that indicates the drive is malfunctioning - that's a hardware problem that cannot be fixed - you must replace the drive. I'm assuming your drive model is capable of reading and burning both CDs and DVDs , of course

You can't format a burnable disk in an an optical drive the same way as you format other things, e.g. a hard drive partition, unless it's a CD-RAM or DVD-RAM disk and your drive model supports reading those types of disks, or unless you use specific burning software such as Nero's InCD for re-writable disks. (InCD allows you to use your rewritable disc like a big floppy disk. Copy files onto your disc using drag and drop or save them to the disc from other applications.)

If you had the upper and/or lower filters problem, it's likely the DVD drive would not work at all in Windows for doing anything.

See response 3, and response 6 regarding cleaning the laser lens.

"If you had the upper and/or lower filters problem, it's likely the DVD drive would not work at all in Windows for doing anything."

E.g. You wouldn't be able to burn both DVDs and CDs.

One thing that hasn't been mentioned is you can have oddball problems if you have more than one third party (was not built into Windows) burning program installed becuause they often have resident modules (a part that runs all the time) that can conflict with each other.
If you DO have more than one of those installed, un-install all of them except one.
