suggestions?

Those messages from dmesg look like a failing drive or cable. Try reseating or replacing the cable. (I've seen this one MANY times). Additionally, does the drive spin at all when you are attempting to mount?

the drivers are working fine under winxp. when i try to mount them there isn't any strange spinning

up

hdd: command error: status=0x51 { DriveReady SeekComplete Error }

That line caught my eye. It could be you have the wrong Motherboard Drivers
installed (probably using Generic IDE). I too had this problem, and recompiling
the kernel with VIA Chipset Drivers fixed it right up.

Or, worst case scenario, failing hard disk. As Matir pointed out.

I believe dvd and cd/rw use a kernel module called "ide-scsi" (I think, could be wrong about the name).

If you use lilo and the 2.4 kernel "append hdc=ide-scsi hdd=ide-scsi" to /etc/lilo.conf, the 2.6 kernel "append hdc=ide-cd hdd=ide-cd", then rerun lilo as root and reboot.

If you are using grub, I don't know.

Who knows I might even be completely off track, but it is simple enough to be worth a try.

Samac

still doesn't work. i've recompiled the kernel with the correct drivers VT82CXXXX
and added the append command on lilo. the error messages are the same as before.
maybe the problem stick to the kernel configuration.

use 'smartctl --info /dev/suspicious_problem_drive' to see if your hard drive or cdrom drive supports Self-Monitoring Analysis and Reporting Technology(SMART). If if does you can use smartctl to ask your drive if it's about to die, it'll be honest. Drives are reliable and dirt cheap now.

Are you trying to mount a cd-rw with a ext3 filesystem on it? I don't think that works yet. You have to use mkisofs with the RockRidge extensions to get features of Unix onto a CD-r/rw.

Your media could be corrupted. Say you made the cd-rw at 24x speed, when the media only supports 10x or so. If you have crucial data on the disk you can use 'dd' to rescue your data from the cd and put the iso-image in a safe place to be analyzed, or you can use cdrecord to "clone" the disk to a file on your hard disk.

You have DMA on. That's good as the new devices has DMA as the industry's "pet feature".

CONFIG_IDE_GENERIC
CONFIG_IDE_CHIPSETS
CONFIG_BLK_DEV_GENERIC is not set. The kernel config tool recommends that you enable those options, you have them as not set. I think it's something to tinker with.

are you trying to mount an audio cd ?
if so...use a data cd.

egag

great! now i can mount my slackware cd... i added the three option as Tmantist adviced me.
ok. almost done.
i can't mount music cd. i tried with -t iso9660. there's another type of fs for music cd?

i still can't mount music cd but i can listen it from the dvd driver with KsCD. that's could be enough for you r patience to aswering to my problems but....
if also the cd-rw plays music will be a really satisfaction!

The audio cd can't be mounted as they don't contain any filesystem,
only audio and index data

Did you try to configure KsCD, so it reads /dev/hdd instead of /dev/hdc ?

to play my music cd on KsCD i had configured to use /dev/dvd (sym link to hdc). when i select /dev/cd-rw, KsCD works regularly but with no sound
