Hoping someone can help me mount both my internal CDROM and USB DVD/RW drives? I also try 'mount -t iso9660 /dev/scd0 /mnt/dvd' without success. I am on kernel 2.4.20-31.9.

My dmesg, 'cdrecord -scanbus', and fstab, follow:

Hmmmmm........

/dev/scd0 /mnt/dvd iso9660 defaults 0 0
/dev/hdb /mnt/cdrom iso9660 defaults 0 0

May be better to use something like;
Not all of the DVD or CD media are iso9660 formatted, some are UDF.

Is /dev/hde set in grub/lilo with the ide-scsi option, or is this the USB device??

What is the /dev/hdb device in your /etc/fstab file??

-----------------------------------------------------------------------------------------
-----------------------------------------------------------------------------------------

Thanks, Lenard. The devices mounted with your suggested fstab entries, but I can't see any of the files on the media in the drives, e.g., 'ls -la /mnt/dvd'! The media were burned using iso9660 (one in Joliet mode) and have about 25MB of data on them.

I think /dev/hdb is the internal ATAPI CD-ROM, while /dev/scd0 is the external USB DVD-RW. In that case, I should mount the DVD-RW with something other than "r0' in the fstab?

I don't know what /dev/hde is. how do I see tjhe grub/lilo settings/options? I tried 'lilo -q' and there is no /etc/lilo.conf

David

First it is 'ro' (read only) in the entries and no cdrecord and growisofs (part of the dvd+rw-tools) are what is needed to write information to the media.

To read grub try something like (as root of course); cat /etc/grub.conf

If you do not know what device is hde then why did you post part of dmesg which has lines like;

hde: read_intr: status=0x51 { DriveReady SeekComplete Error }
hde: read_intr: error=0x10 { SectorIdNotFound }, LBAsect=320159173, high=19, low=1392069, sector=320159110


Please check your /var/log/messages file (again as root);

cat /var/log/messages | grep hde

Lenard,

Can you say why I can not now see the information on the CDROM and the DVD-RW with 'ls -la /mnt/cdrom', etc?

My /dev/dhe/ is a hard drive (red herring) that has just failed. The 'cat /etc/grub.conf' follows:

Actually got the CDROM to work, it was /dev/hda and not /dev/hdb. But, I still can't get the USB DVD-RW to be mounted. I checked the /var/log/messages and the dmesg and I don't see it.

Well, I'm glad you got the CD drive to work.

The USB drive may need the usb modules to be loaded for you system, forget the names used for the 2.4 kernels but look for modules with echi, ochi and uchi in the name.

To find which usb hardware you have; lspci -v
To see if the modules are loaded; cat /proc/modules
To see if you have the usb modules look in;

/lib/modules/<kernel-version-number>/kernel/drivers

Examples ( the output may look different sine this is a 2.6 kernel system);

$ lspci -v | grep USB

$ cat /proc/modules | grep hcd

Hi Lenard,

Thank you for your help. I tried cloning the boot drive and booting a duplicate hardware setup I have and on THAT system the DVD-rw is recognized as /dev/scd0! Wow, how weird.

In any event, here is the data ...

What if any is shown in /var/log/messages after you plug in the USB device???

# tail /var/log/messages

Nothing is entered in /var/log/messages when I unplug, and replug into a different USB port the DVD-RW

Was afraid of this, RHL9 is not very good at newer USB devices..........
With the device plugged in have a quick look at;

cat /proc/scsi/scsi

Hopefully the device will show up. If yes then you should now which scsi device it is.

An example;

$ cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: TOSHIBA Model: CD/DVDW SD-R6472 Rev: TU51
Type: CD-ROM ANSI SCSI revision: 02

I would like to suggest that it is time upgrade the OS to a modern supported version. Staying with the Red Hat family I will suggest CentOS which a freely available version of Linux that is binary compatible with RHEL4.

It's not there, only the 3Ware controller and the scsi Tape drive are there.

I've been trying to upgrade to FC5, but the "assertion at line 485" problem plagues me currently. I've tried the recommendations regarding the sfdisk command (and grub-install) and they fail me so I am trying to upgrade using FC1, 2, 3, 4, to see which one works. Getting the DVD-RW USB drive to work would have been a bonus at this time, before the FC5 upgrade, but I guess not extremely necessary at this point. I'll give up on the DVD-RW for now.

Thank you for all your help.

David

And just for FYI FC1-4 are in legacy mode or are no longer supported;
