Ok, I'm having some issues as well. I've been online and on the phone with Compaq a few times now. My H552L will burn CD's and DVD's just fine, no problems there. Sonic is not recognizing my drive as a lightscribe drive when I go to print the labels to the discs. They are lightscribe discs and everything else is working fine.
Compaq got me to reinstall sonic, update the driver and eventually just reinstall windows (great, lost a bit of information that I forgot to backup because I was in a rush to finish getting it working again. My fault I know, but maybe they shouldn't sell a computer without it working first.)
reinstalled windows. lightscribe worked GREAT! for one disc. Now I have the same problem. It says "there are no lightscribe devices on this system"
I know that there is...my computer is lying to me for some reason.
