Knoppix on iPod?

I would like to save my configurations to my iPod (currently empty FAT32 partitioned) however when I use knoppix-->Configure-->Create Persistent Knoppix Home Directory I see 4 drives marked sda1 through sda4. There is only 1 iPod connected by USB. When I select any of them it says "sda* is not a valid block device." Do I need to reformat them in Knoppix first. I don't plan on using the iPod for anything else.

Im probably missing something, but I just don't know what I am doing wrong.

Can it be done, using the iPod for knoppix? If possible, what I would really like to do is just install knoppix on the iPod HD and use that to run the whole OS. Can that be done?

What you suggest may be possible, whether it's wise on something as flakey as an iPod is quite another question. I'd make sure that you keep a backup somewhere else.

To me, the mount issue suggests that the iPod may not be powered up.

I get similar messages from my (vastly superior!) Neuros if:

the battery is flat and/or it's not plugged into the transformer

I've mounted another usb device and not re-booted (someone posted a work around for this, but I've forgotten it).

Power is not an issue. The iPod reads as having a full battery, and it doesn't even take power from the battery when it is plugged into a power outlet. I have a cable with 2 ends, one USB and 1 firewire that connects the to firewire power adaptor, that it then plugged into the wall. The iPod has full power.

The iPod is the only other storage device that I have that is large enough to work with.

For a temporary fix, I tried saving my settings to a floppy diskette to preserve them between reboots. It doesn't want to do that either. I insert a blank floppy, run Knoppix-->Configure-->Save KNOPPIX configuration and after pointing it to my floppy drive with a blank floppy returns this error "umount: /mnt/floppy: not found".

Ah, that error.

/mnt/floppy doesn't exist!

If you change the entry to

/floppy

you should be OK.

FWIW, my /etc/fstab entry looks like:

/dev/sda1 /mnt/sda1 vfat noauto,users,exec,sync,umask=000 0 0

(the sync entry prevents all kinds of crazy errors)

I'm a bit puzzled as to why you get 4 sda entries: if you're using a multi-card reader or hub or somesuch it might be worthwhile trying a single usb port.

I don't understand. What am I supposed to change? Going to Knoppix-->Configure-->Save Knoppix configuration I am presented with a gui menu asking me to select what configurations I want to change then asks me where to save it. I have only two choices /mnt/floppy and /mnt/sda . Selecting floppy closes the gui box and that's it, I never have the choice to change anything. Where do I change something? If I do it in the konsole I get the /mnt/floppy not found error.

The iPod is not on a hub, it's connected to a single USB port and I have tried it from all the USB ports on my computer (all 6). Same results.

Hi,

This seems to be the same problem I had with my USB memory stick. Four partitions on it, sda1 - sda4.

I did it the hard way: dd if=/dev/zero of=/dev/sda

Create one new partition on sda, FAT type

Format as FAT

Ready.

I don't remember the details, but with a lot 'apropos' (or was it 'man -k'?) I found out how to do these steps. Of course you cannot do anything else anymore with your iPod. (Or you make a backup first? dd if=/dev/sda of=/your_file_somewhere)

HTH

Wait, I wont be able to anything else with my iPod ever? Or I just wont be able to do anything unless I reformat it for music again?

So I will have to reformat the iPod from Knoppix? How exactly do I use that command?

Have you mounted the iPod? If not then there's no way in hell you're going to be able to use it!

What version if Knoppix are you uysing? I'd hasard a guess at 3.4, as the iPod seems to be recognised already... (with 3.3 you have to run a script like rescan-scsi-bus.sh to get firewire drives - iPod included - recognised).

"mount" will list all the partitions you currently have mounted; "sudo fdisk -l" will list all recognised harddrives and the partiions on them.

HTH

p.s. Neuros better than the iPod? <lol> I appreciate the fact that users on this board have a sense of humour ;)

I appreciate the fact that iPod buyers have more money than sense (except, maybe, fashion sense) :wink:

Ah, gotcha. Look at /etc/fstab

vim (gvim, or whatever) /etc/fstab

edit the line

/dev/fd0 /floppy vfat defaults,user,noauto,showexec,umask=022 0 0

to point to /mnt/floppy

(make sure that a directory called /mnt/floppy exists!)

save it

then do

mount -a

and all should be well.

I'm doing this from a HD install so can't actually check it.

Ok, I got the floppy to work and I can now save the config to it. That's taken care of.

Now, when I type "sudo fdisk -l" into the konsole I get this:

knoppix@ttyp0[knoppix]$ sudo fdisk -l

Disk /dev/sda: 10.0 GB, 10000005120 bytes
255 heads, 63 sectors/track, 1215 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 1 5 40131 0 Empty
/dev/sda2 * 6 1215 9719325 b W95 FAT32

Disk /dev/hda: 122.9 GB, 122942324736 bytes
240 heads, 63 sectors/track, 15881 cylinders
Units = cylinders of 15120 * 512 = 7741440 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 15881 120060328+ 7 HPFS/NTFS

So it looks (to me) that it can see the iPod, but when I try and save the home dir to it tells me "The KNOPPIX configuration could not be saved: mount: wrong FS type, bad option, bad superblock on /dev/sda, or too many mounted file systems."

Hmmmm. I'm still confused by the umpteen sda(?)entries.

Apple are strange folk, but is the disk really 4 seperate partitions? How does it appear in other OSs?

My Neuros appears as 1 partition with a number of seperate directories ( a flat structure, except for the /music which has seperate sub directories).

I don't know how many it is in XP (how do I check that?). It does show up as 1 drive F: in WinXP though.

Yeah, I meant one drive (with one partition). If all the directories you expect are on that drive, that would seem to be what it is.

I wonder if Knoppix isn't picking up your usb hub correctly?
