I can't mount any CD/DVD discs
I use prief and full command:
Quote:
mount /dev/hdc mount -t iso9660 /dev/hdc /mnt/cdrom
I tried
/dev/cdrom instead of
/dev/hdc but same problem.
my /etc/fstab entry like this:
Quote:
/dev/hdc /mnt/cdrom iso9660 noauto,user,exec,ro,umask=0 0 0
Error message:
Code:
mount: block device /dev/hdc is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Just out of sheer curiosity, and the thing that you don't mention in your initial post; what kind of cd-rom/dvd are you trying to mount exactly.

Code:
[root@localhost ~]# dmesg -c
After I did what you told me, and I tried to mount it by mount command:
Code:
[root@localhost ~]# dmesg
attempt to access beyond end of device
hdc: rw=0, want=68, limit=4
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16
same tree lines has been repeated after every try.

Just to add.
I think dvd's are udf format instead of iso9660:/dev/hdc /mnt/cdrom iso9660,udf noauto,user,exec,ro,umask=0 0 0 in the fstab so the dvd's are easier to mount in the future.

Well, it's a laptop and I run many Live CDs/DVDs on it.

No, I tried this many times and I got same fail message.
And I just use Data DVDs (specifically: Linux distros like Slackware 12.2 and Fedora 10 ..etc) not VideoDVDs or any kind of UDF data usage.
Thank you.

who is user a?
Hello
The following excerpt from your directory listing for /dev above:
Quote:
brw-rw----+ 1 a cdwriter 22, 0 Jan 25 21:13 hdc
made me wonder if you had a user "a" on your system, or a group "cdwriter"? In typical slackware installations, the optical media device is usually owned by user root and group cdrom; here's the output for my cdwriter which is hda on my system:
Code:
darkstar% ls -lah /dev/hda
brw-rw---- 1 root cdrom 3, 0 2009-02-22 10:02 /dev/hda
Perhaps the user you are logged in as doesn't have permission to use hdc.
