It looks like it is tough to find a solution to this problem. I've been searching all day. The problem is that my DVD/CD-RW drive used to work, now only DVDs are recognized. I've tried numerous CDs, I cleaned the lense, same problem. I'm currently using a NEC LaVie L LL800R/7 laptop running Kubuntu 2.6.12-10-386.

I found this odd little bit in dmesg:
[4294671.758000] Probing IDE interface ide1...
[4294672.550000] hdc: UJDA710, ATAPI CD/DVD-ROM drive
. **Probing other IDE interfaces and finding nothing here**
[4294675.629000] hdc: ATAPI 24X DVD-ROM CD-R/RW drive, 2048kB Cache
[4294675.629000] Uniform CD-ROM driver Revision: 3.20
Seems it is probably the driver, but I remembered with windows it seemed to be some kind of generic driver, although now I'm not sure.
When a DVD is inserted, demsg gives me something like this:
[4298023.345000] ISO 9660 Extensions: Microsoft Joliet Level 3
[4298023.608000] ISOFS: changing to secondary root
Any CD I insert does not even log anything.
Oh, and of course, here is my fstab. As you can see, I have played around with it a little and nothing worked.
# /etc/fstab: static file system information.
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/hda1 / ext3 defaults,errors=remount-ro,atime,auto,rw,dev,exec,suid,nouser 0 1

# /dev/hdc /media/cdrom0 auto ,atime,auto,rw,nodev,noexec,nosuid,users 0 0
/dev/hdc /media/cdrom0 auto auto,user,ro 0 0
I've tried mount -t iso9660 /dev/hdc /media/cdrom0, I've tried some more plain variations. Tried disks burnt in windows and linux. I get nothing. Googled and could find nothing usefull about this drive, but that may be I just don't know what I'm looking for exactly.
Hopefully this is an interesting problem. I'll post any other info I can get if more is needed. Any advice would be appreciated.
