USB disk mounting

[rrfish72]

Add the imm, ppa and usb mass storage modules with modconf. Then when these modules are loaded one of them should help the drive be recognized. imm and ppa are in the kernel/drivers/scsi section. To install them just highlight it and enter through. Must be root. usb mass storage is there somewhere, you'll have to look around. Try the first 2 then add other if they do not work.

I have a similar issue. I purchased a 256MB Cruzer Micro for under $20.00
I thought I could use it to transfer images from a old G3 Mac I have ( I've never gotten linux to read HFS+)

I was able to get the usb flash drive to mount but I couldn't write to it and then I would also get an error
" line 20 in ftab is bad" I deleted the line I made in fstab but does anyone know a quick how-to on usb flash drives?
Thanks

Update: I just found this how-to: http://www.linuxforums.org/forum/post-147912.html
Haven't tried it yet.

I tried this how-to and it did not work i.e. I got the "bad superblock, bad fs, too many mounted FS error"
When I use usbdevfs as the file system the drive can be mounted and unmounted but I can not write to it.
I checked and chmod my permissions but no luck. the message is just can not write "file'/mnt/Cruzer.

Someone might take offense that I say this but I mounted this flash drive in suse with no problem.
I mean, no anything just stuck it in the usb port the machine beeped and 10 sec later
the device icon mounted to my desktop (read&write).
Knoppix has many great features I love it, and it has some failings too.

According to the link above you have to edit the fstab with this entry:

/dev/sda1 /mnt/usbflash vfat noauto,users,rw,umask=0 0 0

To do this, login as root and edit with kate or kwrite. Open-->devices-->partition that is /-->etc-->fstab, just in case you can't find it. Add the line in the middle somewhere,I don't think it really matters.

create a directory:

mkdir /mnt/usbflash

Then I don't know if you have to create a device on your desktop, but try it and see what happens. Like adding a zip drive, you have to add pretty much this same stuff and add the imm module. Hope this helps.

I did all that, but thanks. Actually there is a thread here at the knoppix forum that comes to the conclusion ( I didn't bookmark it) that these Cruzer usb flash drives don't work in knoppix. BTW I have no problem editing fstab I have a digital camera that works fine.

have you tried to reformat it under knoppix? it "might" work, but it might also destroy it... it made my "noname" work under linux.

Thanks for all the response this is a really supportive forum!

Even though this is a rather inexpensive flash drive I don't really want to risk trashing it.
As I mentioned above it mounts in suse without doing anything.
I do 90% of my work in knoppix and the other 10% falls to slackware & suse
plus I can access those other partitions in knoppix so that's how I'll leave it for now.

Thanks again

I'm running a Windows 2000 destop (Fat32) with the 3.7 CD wriiten to a fat32 folder (TOHD cheatcode). I boot from the Knoppix 3.7 CD as user "knoppix", with the FROMHD cheatcode ,and the boot switches to my windows drive (/dev/hda1) 10 seconds into the startup. I also have an old Seagate 4.3 GB drive conected via a USB 1.0 external enclosure. Knoppix sees that as /dev/sda when I boot up. I used QTParted to make two partitons on the USB drive, a 2.3GB linux partition to use as a persisten home directory, (/dev/sda1) and a 1gb Swap file (/dev/sda2). Provided I turn the power on for the drive, Knoppix sees both of them with no modification necessary. My suggestion is this: Connect you usb device, stick, drive, whatever, power it up if it needs external power, and then boot from the knoppix CD. When the KDE destop apears , look for /dev/sda1 on the destop. if it's not there, it probably isn't on the knoppix compatability list. I can see /dev/sda1 as a drive icon, but it was originally read only. I changed it to read write once, and it has stayed that way. /dev/sda2 isn't visible, but I see a line in the startup screen that confirms than Knoppix has mounted it. I've heard that as of Linix kernel 2.6, USB devices are notw being assigned /dev/USBx codes instead of sharing the SDAx with the scsi devices, but that doesn't seem to affect the Knoppix 3.7 boot CD . If the boot CD can't find it, I don't see how a HD install could . LIke Phil Jones's free guide "Knowing Knoppix" says , Not Everything Works. C'est la Vie !
