It should work. Try running
cdrecord -scanbus to see if it is seen as a mass storage device. Make note of it's location on the scsi bus. My USB thumbdrive returns this:
Code:
scsibus0:
0,0,0 0) 'CRUCIAL ' 'USB DRIVE ' '1.12' Removable Disk
0,1,0 1) *
0,2,0 2) *
0,3,0 3) *
0,4,0 4) *
0,5,0 5) *
0,6,0 6) *
0,7,0 7) *
0,0,0 is /dev/sda1. You need to make a mount point directory for it and then:
mount -t vfat /dev/sda1 /mnt/zipdrive
You'll have to make the "Save Config" floppy to reload the setting when you restart Knoppix.
