I cannot burn cds or dvds. The dvr drive will not recognize any blank disc.

Does the cd/dvd drive read cds? This is a good test to ensure that the drive is functional.

Sometimes, generic cd/dvd burners do not recognize certain types of blank discs. Try another type of
brand blank discs, it should work.

This problem is normal and exists with many CD/DVD drives.
On some of the drives, if you put in blank discs and try to open the disc in My Computer or Windows Explorer, Windows displays no contents or a blank disc. Whereas on other drives, you get the error message that you mentioned about incorrect function.

What software are you using to burn CDs or DVDs? Are you able to burn CDs but not DVDs or you can't burn both the discs? Did you try a CDs with a different make/manufacturer? Some drives refuse on some disc makes. Try another disc and another writing speed, or try the lowest writing speed available with your software.

Hope that helps,

Sounds like the lens is dirty. Run a cd cleaner through the drive. That should take care of it.

A blank disc is RAW until something is burn to it the burning program will format it to cdfs.

try isolating the problem by plugging an external cd/dvd drive via the USB. use this to burn CD/DVD if the process works, replace your laptop dvd drive.

Usually HPs are good with +R DVDs unless things have change over the last year or two.

Whats the model number on your computer?

Did you try a DVD firmware update? Some dvds need new firmware to reconize some DVDs

Alright. Seems like Windows, for some reason, doesn't think your drive is able to burn things when trying to deal with this kind of disc.

I'll need further information, like if you use another program to burn music CDs, and what other things might have changed the registry settings. I know of a fix that resolves issues with the Windows version of data CD burning, but it only applies to CD-R and CR-RW drives..

Have you checked device manager to see if you have a yellow checkmark on your DVD./CD drives? if ok, sounds to me like the maker of the LH-20A1l BLO5 either needs to fix your problem or replace it. The Nero 7 should enable it to work correctly.

okay guys here's your solution use memorex dvd-r disc in these drives these are the most compatable disc out there.
