    Continuing LS-120 problems

    Still unable to mount LS-120. Read the previous advice. dmseg|grep LS-120 shows it as hdd: etc, etc, but nothing seems to work when trying to mount it. Notwithstanding, this guy doesn't really know what he's doing in Linux. Some detailed and explicit advice would be most appreciated.
    Thanks,
    OG.

    In kde, right click on the icon for the ls-120, and change the device to /dev/sd0. Knoppix recognizes these drives as scsi devices.

    Two problems, L2. There is no icon. I'd have no idea how to 'change a device'. Right clicking on anything that shows the floppy (as fd0) doesn't offer any sensible options. Please: I need it spelled out. Sorry.

    Assuming that L2cache is right about the scsi emulation then you should be able to see where the device is connected on the bus by using cdrecord -scanbus or dmesg | grep scsi to see the boot messages related to scsi. Could you post the output of these two commands plus the contents of /etc/fstab if the ls120 does not show up in the commands then post the relevant section(s) in the dmesg where the drive gets detected.

    Thanks a C$m, Stephen. Here is the output of three shell commands. The drive is there OK. Regretably, I neither understand the implications nor how to procede, but I'm trying. Some of my friends agree - I'm trying!

    Look at this line:
    scsibus0:
    0,0,0 0) 'MITBISHI' 'LS-120 COSM 05' '0510' Removable Disk
    and this line:
    Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0
    look in /etc/fstab for a line that starts with:
    /dev/sda ... ...

    if you did your install without a disk in your ls-120 you may not have an entry in your fstab for your drive.

    if there is no entry in your /etc/fstab file then do an ls on your /mnt directory:
    ls /mnt
    see if there is an entry (mountpoint) for sda in there, if so then try this :
    (as root) mount -t vfat /dev/sda /mnt/sda
    if /mnt/sda does not exist you can use (as root) mkdir /mnt/sda to make it.

    post back your fstab and we can help you further.

    Also boot up with a disk in the drive to keep from having a ton of scsi errors

    Thanks, rock. Here is the fstab output:

    I am wondering whether the confusion lies in the 4-port USB hub and/or the USB card reader. The former recognises my printer but doesn't print through it, so I've used the rear-mounted ports. If you can help me fix the LS-120, maybe it'll fix that problem too? Two for the price of one. Where do I send the beer vouchers?!

    In KDE, in Knoppix 3.2, for an internal LS-120 drive, right click on the desktop, select create new, floppy device. Name it LS-120, and set the device to /dev/sda, then click ok. This should give you a desktop icon for the LS-120. Put a floppy in the drive, click the icon, and it should display the files in konqueror after a few moments. Knoppix recognizes these drives as scsi devices. To remove the floppy, right click on the icon and select unmount.

    Unfortunately, it hasn't proved that simple, L2. I did all the things you suggest and a whole lot more. I can get the floppy icon on the desktop, I can name it LS-120 and set it to /dev/sda in the Device Tab, but it then needed to be associated with a file type. I chose Konqueror Web Browser following your advice. However, this only produces an error message about being 'unmounted':
    "There appears to be a configuration error. You have associated Konqueror with kdedevice/floppy_unmounted, but it can't handle this file type."
    Using right click+Mount doesn't help, nor a lot of other variations. It now shows type as /dev/scsi and some combinations of fiddling produce an error message about inode errors. Bizarre! I am no newcomer to PCs but Linux is continuing to confuse me!
    I guess this level of manipulation is unacceptable for Joe Public?! I continue to be grateful for your time and efforts, guys. What next?!
