C840 Not Recognizing Drive
I purchased a CD/DVDRW drive for the front bay of my C840. After installing it and booting up, a detection screen came up, looked like it had something to do with the BIOS, but then went away and the machine booted. The BIOS recognized the drive as a CD ROM, and Windows recognizes it as a Matshita UJ-860s. It appears that only the first 640MB of a DVD are readable. None of the DVDRW firmware drivers from Dell seem to recognize the drive. Actual code on the drive is KR-03U362-35831-318-7894. Any suggestions? Thanks.

Does the BIOS (F2 at powerup) in fact see the drive?
IF it doesn't, is there a working hard drive in the system? The optical drive shares the same channel with the hard drive - if the hard drive isn't seen, neither will the CD/DVD drive be seen.

firmware has nothing to do with it; you need software
the freeware VLC should enable you to watch a DVD

Thank you for the reply. I haven't tried playing a DVD movie, only data. I put in an install dvd from Bentley (VW service manual) and it would see the root and file directory, the install program, but not all of the data files. I put the same disk in my xps1330, and it saw the whole disk. Do I need software with the 840 running XP in order to see an entire data DVD?

There is a working HDD in the system. The bios does see the optical drive, but as a CD ROM. When the drive does recognize a disk with the options pop-up, it offers to play the CD. There doesn't seem to be any way to set the drive type for an optical drive in the BIOS. I expect with the right firmware, the BIOS would recognize it properly.
