I'd say it's most likely the drive isn't hooked up properly.
Does the BIOS recoginze the drive when you boot up the computer? Have you verfied the master/slave jumpers and using an 80 pin IDE cable?i'm pretty sure it's plugged in correctly, it shows up as hp dvd640v in the setup menu. but i says that i can't find the correct hardware. i may have the jumpers wrong, but its the only drive on the cable. you put the jumper sideways for that right? when i open the lightscribe program, it doesn't show up as an option for printing. i haven't been able to try it for dvd reading/writing yet. i don't have any dvd r disks.
There is no such thing as a downloadable driver for optical drives.
but there is no downloadable driver? then what do i do, i don't want to buy a disk and find out it's the wrong one.
