see http://www.knoppix.net/forum/viewtopic.php?t=26972 more basic stuff - the second post for more info

Try in a terminal as "root" say: mkdir /media/sda1 (if it does not exist - check your media directory first!)
then say: mount /dev/sda -t vfat /media/sda1 (and see if it mounts)
You may have to modify fstab in /etc/fstab by adding a new line with the device you want to mount
eg:
# Added by root
/dev/sda1 /media/sda1 vfat noauto,users,exec 0 0

for Live CD only - then save your config in "start - knoppix - configure - save knoppix configuration" so it boots with the changes the next time you use knoppix -- - at the boot prompt press F2 and type knoppix myconfig=scan to load your configuration file on hard disk.

That Works fine but I can't change the Read Write mode for the mounted drives

Go back and read the notes at the bottom section of the post referenced in the last post (above0

1. BEFORE you mount a drive set the read and write check box in the properties/device tab then mount the drive.

If you mounted a drive in a terminal you still need to un-mount then remount with the new settings or set the variables in fstab or mtab in your /etc/ folder for the changes to take effect
further you can create and assign a group name to have such permissions to devices and special functions from SETTINGS - USERS & GROUPS in root.
Your best ally is to read the info & manpages for instructions.

Thanks
Got that working

But what happened to the simple right context menu Change read/write mode. Nothing happens anymore


When i plug unplug the device it doesn't disapear on the desktop

is there a way to make them read/write always. usb listed as rw in mtab. and i even tried adding the rw param in fstab, but nothing happens

I don't know the answer to that?
However I suspect (in my case anyway) because the drive was formatted in Windows as a DOS partition the problems emanate from UNIX reading the blocks from zero instead of the offset created when windows formatted the drive.
see my other post for a brief description about FAT drives created in windows vs. UNIX.
I have another USB formatted in ext2 to test that theory but have not had the time yet.
If you find the answer please share your results.

Peace & Prosperity,
