Dear Amir, I have found a partial solution to my problem (see older message below) and I am communicating it to you in case it will be of help to other users of Disk on Key. As you will see it is not very user friendly (one has to be able to e root, problematic with many disk on keys or other devices using usb-storage) so in a sense the question remains. But still it is possible to plug the device many times without rebooting:
1. Insert Disk on Key 2. Mount Disk on Key 3. ....use... 4. Unmount Disk on Key 5. rmmod usb-storage <--- here user root is required 6. Remove disk on key 7. Re-insert Disk on key 8. Goto 2. In this way the device number (in /proc/bus/usb/001/) continues to increase each time the key is re inserted but the key is re initialized and I am able to mount it. See the above cycle in the system log (/var/log/messages) from 5. -> 5. Feb 18 21:32:14 m kernel: usb.c: deregistering driver usb-storage Feb 18 21:32:14 m kernel: scsi : 0 hosts left.

I would appreciate any help you could give me, especially on the problem of mounting disk on key multiple times on the same session (Question 3), since this is crucial for using it on my workstation at work which I don;t want to reboor without serious reason. 1. I am using mkfs to create a Linux filesystem and mkfs.msdos to create an MSDOS filesystem to be used with windows. Since I need to switch from one to the other, is there a possibility to damage the hardware of the key by frequent refomatting? Whare are the limits if known? 2. Is there a filesystem that keeps ownerships and permissions of the linux file system and at the same time is readable by windows that can be created on disk on key and how? (like iso9660 used on CDs?) I do not dare trying without asking you.... (fdisk has a c command for changing a dos compatibility mode, but is that all?) 3. I have problem mounting Disk on Key after plugging it for the second time or more during the same session. This results hanging of the commands mount /mnt/diskonkey fdisk -l /dev/sda (/etc/fstab entry: /dev/sda1 /mnt/diskonkey auto noauto,owner,user 0 0 ) or sometimes the umount command hangs (it happened to me only with a dos filesystem). Then I cannot even reboot the system (kill -9 fails too as expected), I have to switch off the machine. What I see in /var/log/messages is that the second,third etc time I plug the machine is - ---------------------------------------------------------------------- Feb 12 23:36:29 m kernel: usb.c: USB disconnect on device 2 Feb 12 23:42:06 m kernel: hub.c: USB new device connect on bus1/1, assigned device number 3 Feb 12 23:42:09 m /etc/hotplug/usb.agent: Setup usb-storage for USB product 8ec/10/200 - ---------------------------------------------------------------- and then a entry /proc/bus/usc/001/003 appears (003 becomes 004, 005 etc each time I reconect).

Some of the files there know it is a M-Systems disk on key. I attach some extra information on my system in case it will be helpful. /var/log/messages is attached separately in case some information in it could be useful for you.
