root@1[knoppix]# mount -t vfat /dev/sda4 /mnt/zip
mount: /dev/sda4 is not a valid block device
root@1[knoppix]# mount -t msdos /dev/sda4 /mnt/zip
mount: /dev/sda4 is not a valid block device

I have to do this with every one of my drives. dvd,cd,floppy,zip, and get my scanner to work. So far I have dvd,cd working. Your help is appreciated with this zip issue.

root@1[knoppix]# modprobe imm
root@1[knoppix]# mount -t vfat /dev/sda4 /mnt/zip
root@1[knoppix]# mount -t msdos /dev/sda4 /mnt/zip
mount: /dev/sda4 already mounted or /mnt/zip busy
mount: according to mtab, /dev/sda4 is already mounted on /mnt/zip

I guess that is good. Now here is what I get when I try to read the disc:

Access denied to /mnt/zip

[Markus]

root@1[knoppix]# mount -t vfat /dev/sda4 /mnt/zip
root@1[knoppix]# mount -t msdos /dev/sda4 /mnt/zip
mount: /dev/sda4 already mounted or /mnt/zip busy
mount: according to mtab, /dev/sda4 is already mounted on /mnt/zip

This looks promising. I'd say vfat worked there since it errored out when you tried the second command.

Type mount to see whats mounted and how.
How are you trying to access it, cd /mnt/zip should work
Do also:
chmod 770 /mnt/zip
chgrp disk /mnt/zip
And check that your user is in the group disk by typing groups as user, if not, do:
adduser rrfish72 disk

root@2[knoppix]# mount

It's mounted ok so try cd /mnt/zip

root@2[knoppix]# chgrp disk /mnt/zip
chgrp: changing group of `/mnt/zip': Operation not permitted

Try unmounting first with umount /mnt/zip , might as well change the group to floppy instead of disk, my bad. So: chgrp floppy /mnt/zip

root@2[knoppix]# su chgrp disk /mnt/zip
Unknown id: chgrp

Doesn't work that way, you're already root, besides as user you can do sudo command, not su command

root@2[knoppix]# groups
root knoppix

Do groups as user, not root.

[rrfish72]

knoppix@4[knoppix]$ groups
knoppix root disk mail dialout fax voice cdrom floppy tape sudo audio dip www-data backup video games users usb scanner captive

knoppix@4[knoppix]$ chgrp floppy /mnt/zip
chgrp: changing group of `/mnt/zip': Operation not permitted

root@2[zip]# adduser knoppix floppy
The user `knoppix' is already a member of `floppy'.

root@2[root]# umount /mnt/zip

[Markus]

Your user shouldn't be part of the root group, if you feel more comfortable with using a GUI you can use kuser to set groups for your user.
Or do: deluser knoppix root (be a bit careful with the deluser command as it can delete a user and his homedirectory when used wrongly)

After umounting you can again check with mount that the zip is no longer mounted, then try with chgrp floppy /mnt/zip (this you have to do as root)

When done, try mounting again: mount -t vfat /dev/sda4 /mnt/zip
And try to access it or list it: cd /mnt/zip or ll /mnt/zip

[rrfish72]

After doing modprobe imm and mount -t vfat /dev/sda4 /mnt/zip then does it show up as being mounted. Here is what was done again to get it mounted:

root@0[knoppix]# mount

Not sure about the deluser thing yet. Do I deluser knoppix root when I'm in root? Don't quite understand the group and user thing. What is that setting? Permissions.

After it is mounted:

root@0[zip]# ll /mnt/zip
total 4
-rwxr--r-- 1 root root 4079 Feb 15 1995 readme.txt

Can you walk me through the deluser? I added ithe modprobe imm to that boot.sh file here:

# Save kernel messages in /var/log/dmesg
#
dmesg > /var/log/dmesg
# This was added by Ryan
modprob imm
Is this correct

You do it as root, but if you're unsure of it, use kuser for it as it's a risky thing to use. Different groups have different access rights and permissions, also a users access rights depends on which groups he belongs to, root always has access to everything. Therefore a user shouldn't be part of the root group.

After it is mounted:

root@0[zip]# ll /mnt/zip
total 4
-rwxr--r-- 1 root root 4079 Feb 15 1995 readme.txt

If that's all there is on it, you just managed to access it. Now you can start adding the line to fstab.

I added ithe modprobe imm to that boot.sh file here:

# Save kernel messages in /var/log/dmesg
#
dmesg > /var/log/dmesg
# This was added by Ryan
modprob imm
Is this correct

AFAICT thats correct once you've changed the modprob to modprobe ("e" missing), you could also try doing insmod usb-storage while it seems to be needed, and hopefully it's loaded after a reboot, check with lsmod.

[rrfish72]

Does not show up after reboot.

Well, it's the knoppix style install again recreating your files, don't know much about that type of install, so let's try to get your CD drives working first and go from there.
