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.>
OK, figured out a way:

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.
Excellent. And thanks for posting back.Quote:

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.Quote:

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

Yes, it does. So does QParted, and they show up when I boot with Kanotix.Quote:
fdisk -l /dev/uba

su first...I'm learningQuote:

df -HT /mnt/uba9
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.Quote:

Knoppix just doesn't like that big FAT partition (although Kanotix has no trouble with it)
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.Quote:

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.
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 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]
> Actually, it's plugged in when I boot.
What is then the fun of having a hotpluggable drive when you must have it plugged when you boot?
