Your output for /dev/hdc looks just fine, as far as I can tell.

Please do 'dmesg | grep hdc' to see if there are any related messages in there. Post output if you have any questions about it.

Also, you might want to change your /etc/fstab from iso9660 to 'auto' for the filesystem on your DVD (and, optionally, CD) drive(s). DVDs actually use the udf filesystem, though most also have iso9660 behind that (but not all do, as far as I know).

I was supposed to get this, right?
Code:
# dmesg | grep hdc
    ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA
hdc: DVD-ROM BDV316C, ATAPI CD/DVD-ROM drive
hdc: attached ide-cdrom driver.
hdc: ATAPI 1X DVD-ROM drive, 512kB Cache, UDMA(33)
/dev#

Ok done.
How do refresh without rebooting?

There is no "refresh" needed. Just try to mount again.

Try this : mount the dvd as said before, after you do that run tjis command: tail /var/log/messages , it should list the last ten lines of the system log which will contain i hope info about what goes wrong with the dvd mount. just post the outcome!

Hi koloth,
I tried that and got:
Code:
# /var/log/messages
-bash: /var/log/messages: Permission denied
So I changed the properties of /var/log/messages to "executable" and got this:
Code:
# /var/log/messages
-bash: /var/log/messages: Text file busy
#
I then opened it in kwrite. so here's the last 10 lines:
Code:

This what you were looking for?

It does mention in there that it could not open the cdrom drive, which is odd.

Currently,
/dev/dvd should be a symlink to /dev/hdc, correct?
/etc/fstab should point to /dev/dvd for that drive, correct?
/etc/fstab should have the "user" option for mounting it.

What error message, precisely, do you get when attempting to mount it right now?

Yep.

Since the device has been recreated several times, could you please post the output of
Code:
ls -l /dev/hdc
again?

I'm wondering if the system is having a hard time sending it commands for some reason. Naturally, you have a (known) good cd or dvd in the drive?

Hrrm, very odd. Almost looks the same as my install, except my permissions are a tad more restrictive. (brw-rw----)

I doubt this will have much effect, but please try doing it as 'mount /mnt/dvd' by itself, without specifying the device.

Hrrm. I'm beginning to become stumped with this one. Is the drive known to work? (I.e., no hardware issues, checked cables, etc.)

Does the drive spin at all when you try to mount it?

Hi Matir, Yes the drive does work, or at least did in the beginning, just after I moved from windows. It stopped working when I had to re-install Mandrake 10.0 the first time. Since then, I've not been able to get it to work with any distro. I've tried SUSE 9.2, Knoppix, Ubuntu (LiveCD and Installed). They all see the dvd, but refuse to read/mount it.
