Boot knoppix without the USB drive attached. Then type this in a root terminal window:

Code:

dmesg -c > /dev/null

Attach your USB drive and type the following code:

Code:

( set -x
uname -va
cat /etc/knoppix-version
lspci
dmesg
cat /proc/partitions
) >& post.txt

Please post the output of post.txt

Can't do this. Don't know enought about Linux.

Did it once when I switched to 'shell 2 ?' as root, but couldn't copy the post.txt to ubb1 (not writeable)
When I switched to shell 5 (the GUI), in which I know how to make ubb1 writeable, couldn't find post.txt from shell 2.
Tried again in GUI shell console; dmesg -c > /dev/null 'Operation not permitted'; tried again with su, but don't know enough to make that work.

Best I can tell uname -va produced Linux Knoppix 2.6.11 #2 SMP
lspci produced two USB controllers and a hub.
cat /proc/partitions showed ubb1 (the pendrive), and ubba (the external Maxtor) 5,6,7 (linux partitions)
but NOT the one I really need, uba9, the large FAT32 partition.
dmesg is 14k (I assume your first instruction would clear that, but I can't make it work).
I do see one line "FAT: invalid media value (0xb9); VFS: Can't find a valid FAT filesystem on dev hda"
That's the NTFS windows "C:\" drive; I can read from it fine.

And in my first try with Kanotix, everything appears to be working fine (uba9 is accessible)
<well, not everything. I can't figure out how to load myconfig...and the two USB devices, while accessible, seem to switch places after a reboot.>

It's ubb9 (the big FAT partition) that I need to get at.
I've found problems with Kanotix, too, but it mounts that partition just fine.

Knoppix recognizes your USB card. That's good.

Knoppix found both USB devices. That's good, too.

Knoppix sees most but not all of your partitions. I'm wondering if this is a limitation of the USB driver trying to act like a SCSI device. IIRC, SCSI drives can have only 8 partitions. If that hold true for USB also, then you would not have any partitions 8 or higher. I hope I'm mistaken. I'll play around with my USB and FW drives to see if I can partition my drives similar to the way you have yours.

In the mean time, have a look at the partition table of uba:

Code:

fdisk -l /dev/uba

Does that list all the partitions?

What happens if you try to mount it manually? That is:

Code:

mkdir /mnt/uba9
mount /dev/uba9 /mnt/uba9
ls -la /mnt/uba9
df -HT /mnt/uba9

]Excellent. And thanks for posting back.

Well, I'm the one who's asking for help...

fdisk -l /dev/uba

Yes, it does. So does QParted, and they show up when I boot with Kanotix.

What happens if you try to mount it manually? That is:
Code:
mkdir /mnt/uba9
mount /dev/uba9 /mnt/uba9
ls -la /mnt/uba9
df -HT /mnt/uba9

su first...I'm learning

after mount /dev/uba9 /mnt/uba9 I get "special device /dev/uba9 does not exist"

I've tried disconnecting the USB devices one at a time; no change.
Knoppix just doesn't like that big FAT partition (although Kanotix has no trouble with it)

**Albretch** · 09-21-2005, 04:15 PM

So you are saying that kanotix

http://distrowatch.com/table.php?distribution=kanotix

had no issues handling FAT FAT32 partitions from external USB drives?

THis is my problem too

I wasn't able to solve my problems. I had a technician tell me that I had to plug the USB drive before knoppix boots, which made me wonder what was the idea then of using a USB device.

Let me try kanotix then

I have noticed lots of problems with USB/Firewire devices with my knoppix distro 3.9

I am still wondering if there is anyone outthere using knoppix with external devices.

That's right, athough I've had problems with Kanotix saving a configuration.

I have two USB devices attached to a laptop during boot, a FAT16 pendrive and an external 250GB Maxtor.

The external Maxtor wound up with 8 partitions, although I only created 4 Linux partitions and one FAT32 partition.

Both are recognized by both Knoppix and Kanotix. The FAT32 partition on the Maxtor is recognized by Knoppix (QParted shows all of them), but I can't seem to get it mounted.

Kanotix mounted all of them.

I'm looking at /dev and /etc/fstab to try to figure out the difference; but I need to spend some time on a linux book first.

What I'm trying to do is create an external drive that will RUN Linux (probably has to initially BOOT from a CD/DVD) without wrting anything to the Windows C:\ drive.

**Albretch** · 09-22-2005, 06:36 PM

Actually I have a Maxtor Drive too (a MAXTOR 6L080J4, ATA one) inside a wiebetech enclosure with 2 Firewire connectors and one USB one.

After burning a kanotix copy (I liked it already, for some reason it is faster than Knoppix!! (and I don't think that the reason is that the default lang of most applications is German

, which by the way I speak))

I got some info from

http://wiki.kanotix.net/CoMa.php?CoMa=usb-storage

but it appears to be for digital cameras only?

I see the LED on the drive reacting and running /etc/hotplug/usb/usb-storage, shows me

knoppix@1[knoppix]$ cat /var/log/hotplug/usb-storage.log

Then I tried a number of things, none of which worked

Could you tell me exactly how is it you mounted you external ATA drive using kanotix?

Thanks

I' auch. Bin aber Schwab, kann also kein Deutsch schreiben

I plugged it in.

Actually, it's plugged in when I boot.

In my case, both Knoppix and Kanotix recognized the USB device(s). On one laptop, I have two Maxtors (One-Touch), on the other, a Maxtor and a pendrive.

My problem is that Knoppix doesn't recognize the FAT partition on one of the Maxtors, while Kanotix does.
Both Knoppix and Kanotix recognize the single NTFS partition on the C:\ drives and the Linux partitions. Both recognize the single FAT16 partition on the Pendrive. Robert has speculated that I may have too many partitions on the drive Knoppix won't read, and I'm beginning to think he may be right. I tried deleting one with QTParted, but it wouldn't let me. I'll probably try deleting one in Windows eventually.

But at the moment I'm working my way through O'Reilly's "Running Linux"; there's too much I don't understand yet.[/quote]
