Help needed to run a SCSI Jaz drive.

oldtrout · 04-29-2005, 05:48 PM

I am very new to the Linux world.

I am currently running Suse Linux Professional 9.1

When I installed Linux it correctly identified all of my on board hardware with one exception, my internal Iomega SCSI Jaz 2GB drive. This drive is attached to an older WD PCI scsi card which according to the hardware identifier in YAST, Linux does see. However, it does not see the Jaz drive attached to it.

I have tried booting with and without a disc in the drive, and have tried inserting a disc once Linux has booted to see if Linux would pick it up. It did not do so.

I have no idea at all as to how to get access to the drive under Suse Linux 9.1

As I am so new to the Linux world, I do not even know where to begin to try to resolve this problem. Any help anyone can offer in helping me both see and use the drive will be GREATLY appreciated.

I have executed MOUNT under a root terminal session and my hard drive and two cdroms are listed, but not the Jaz drive. I have also exectued dmesg |grep hd and in the response I see no mention of a Jaz drive.

I am now at the limit of my experience and need help to go from here.

Thanking you in advance for any help you may be able to provide...

Besides typing mount to see what is mounted, have you tried to mount the jazz disk?

Try as root or 'su':
1- inserting the jaz disk
2- type: mkdir /jazdisk
3- type: mount /dev/sda1 /jazdisk (or maybe: mount -t vfat /dev/sda1 /mnt/jazdisk )
4- type: cd /jazdisk
5- type: ls (if files are on the disk, they should show up)

Try this, and post if it works, or where you get stuck w/ any error messages.
good luck

I've got an internal iomega scsi zip-100 disk here, we should be able to compare and see where things go wrong. First please post the output of this command.
$ cat /proc/scsi/scsi
This should identify if the scsi disk is seen and what ID it is currently set to. This is what mine looks like, you can see the ZIP disk in my list, and you should see your JAZZ disk in your list. Note it does not matter if there is a disk in the drive or not.

Code:

$ cat /proc/scsi/scsi

If the Jazz disk shows up, then do the following.
Log in as root this time, and run this command
# tail -f /var/log/messages
Your syslog file may be different on your distro, you'll have to figure out what that is first.
The last 10 messages from the syslog file should be displayed and the command prompt will not return (yet).

Now put the disk in the jazz drive and some new messages should print out within a couple seconds. This is the output I get when I put in my zip disk into the scsi drive, you should see something similar.

Code:

Apr 30 22:24:13 entropy kernel: sdc: Spinning up disk....ready
Apr 30 22:24:13 entropy kernel: SCSI device sdc: 196608 512-byte hdwr sectors (101 MB)
Apr 30 22:24:13 entropy kernel: sdc: Write Protect is off
Apr 30 22:24:13 entropy kernel: sdc: cache data unavailable
Apr 30 22:24:13 entropy kernel: sdc: assuming drive cache: write through

Apr 30 22:24:13 entropy kernel: sdc: assuming drive cache: write through
Apr 30 22:24:13 entropy kernel:  sdc: sdc4

This tells me that to mount my zip disk I'd have to run the following commands as root.
# mkdir /mnt/zip
# mount /dev/sdc4 /mnt/zip
You may need an option, like -t vfat or -t ext2, depending on how your disk was formatted.
