can't mount DVD (unknown filesystem 'iso9660'
 

I'm using Debian 4 (kernel 2.6.17),
this debian was installed (let's say) on computer1 (my old pc), I bought a new pc (let's call it computer2) with Sata 250 HDD and I copied the partition from computer1 to computer2,
when I booted with the new debian on the computer2, I couldn't mount DVDrom and even I don't find /dev/cdrom in the /dev directory and no /dev/sr0, when I try to mount it using :
#mount -t iso9660 /dev/sr0 /mnt/cdrom
it says : unknow fileSystem type 'iso9660'
I tried -t cdfs , but still unknown file system
I can't also mount my windows partition: sda1
it says that vfat is unknown !!
I could only mount ext3 file system : mount /dev/sda9 /mnt/redhat

when I was using this debian on my old computer (computer1), cdRom where mounted automatically

an other thing is that I can't install debian on this computer, when installin it says that my cdrom drive is not found and I have to select it manually, but I tried all the drivers that are in the list but no one was good,
my DVD reader is working perfectly with mandriva and redhat but not with debian

so my two questions:
- how can I mount this DVD
- how can I install debian (is there any option to pass when installing debian on a Sata HDD)
and thank you for your help ... !

Look at the contents of /proc/filesystems. Is iso9660 listed? If not double check your running kernels .config file. You may need to reconfigure and rebuild your kernel:
If it is built as a module then you may need to modprobe the kernel module.

I tried cat /proc/filesystems , and I got :
nodev sysfs
nodev rootfs
nodev debugfs
ext2
cramfs
ext3

is it the right way to do what you want ?

sorry for more than one post per time :

I chaecked now the /boot/config...... file , i found :
config_iso9660=m


this problem is similar to mine :

So does the DVD Drive in your new PC have an IDE or SATA Interface ?

it's an IDE , and was working perfectly with this Debian when I was on my old Pc , I still have the same DVD drive.

So it is configured as a module. Try "sudo /usr/modprobe iso9660" and then check /proc/filesystems again.

thank you, but it says :

FATAL: could not load /lib/modules/2.6.17-5mdv/modules.dep: No such file or directory

I loocked in the file modules.dep but I didn't find iso9660

what about installing Debian, is there a special thing to enable sata drives, because when the installertries to detect my dvd drive it says that it's anknown drive, and asks me to choose a driver from the list, but no one is good,,,,,,

I think that the problem the SATA drive,
I have desabled SATA from the BIOS, and then i tried to install debian and the installer has detected the CD drive correctly,, so I think that the problem is the SATA drive,
I found this usefull : http://linuxmafia.com/faq/Hardware/sata.html

Do I have to recompile my kernel so that it supports the SATA drive, if so what options do I have to enable in the config file

You need to run "depmod -A" as root. You may need to install the mod-init-tools package if you don't have the /sbin/depmod program. This command produces the modules.dep table that you are missing. The table lists the dependencies of the kernel modules.

Just a thought, as have been thus fiddling withall.

Are you using udev? If so got to /dev/drive/by-id/ or so, and look for a name that looks like that of the problem drive. Use that name in /etc/fstab, etc., etc.. It is a persistent name and should always point to the drive.
