Subject: Unable to read DVDs - what could be wrong?

(Using kernel 2.6.16rc2 on amd64)

I have this dvd writer:
hda: PLEXTOR DVDR PX-712A, ATAPI CD/DVD-ROM drive

It works well for reading and burning CDs, but it seem to be unable to
use DVDs.

I tried to mount a dvd, and got "No medium found".
cat /dev/hda also got that message, so it can't be a missing fs driver.

I only have one data dvd - it could theoretically be broken.
But attempts to play movies are equally fruitless, and I know those works.

Booting with a dvd in the drive gives me this in dmesg:

VP_IDE: chipset revision 6
VP_IDE: not 100% native mode: will probe irqs later
VP_IDE: VIA vt8237 (rev 00) IDE UDMA133 controller on pci0000:00:0f.1

ATAPI device hda:
Error: Hardware error -- (Sense key=0x04)
Tracking servo failure -- (asc=0x09, ascq=0x01)
The failed "Read Cd/Dvd Capacity" packet command was:
"25 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 "

I have upgraded the device from firmware 1.01 to the latest which is
1.07. That and a cold boot changed nothing.

Am I doing something wrong/stupid here? Strange if it is broken,
I haven't used it that much and it is flawless with CDs.

I have that same model working flawlessly under 2.6.15.
Could you build a vanilla 2.6.15 kernel and test with that?
NOTE: Do NOT configure ide-scsi. There are issues with it
which probably won't be resolved.

I code, therefore I am

You will need to do some troubleshooting to see if it looks like a
software or hardware problem, i.e. plug the drive into another computer
and/or OS and see if those work. If it doesn't work anywhere with dvd
media, it is entirely possible that the blue laser in the drive has
died, and you will need to follow the manufacturer's technical support
system and RMA process. I recently had a DVD combo drive blow out its
red laser so it would recognize dvd media just fine, but any and all cd
media it would report that there was no disc in the drive.

In any case, this mailing list isn't really a general support forum so
you should look elsewhere unless you have reason to believe it is a
problem in the linux kernel.

That seems to me like a broken drive. It is possible for it to be unable
to read DVDs but still read CDs, often these use different lasers.
