Missed tabs on devices properties (and device icons)

Hello, I am doing a Knoppix customization based on Slackware Linux.
I note 2 thing that I cannot understand:

1) When I right-click on a device-icon on kde desktop in Knoppix there are 4 Tabs (General, Permissions, Device, Metainfo) while when I do the same thing on my customization there are only the first 2 Tabs, General and Permissions, while Tabs Device and Metainfo are missed. Do you know why ? This should be important because in the Device Tab there is the 'Read only' flag.

2) When I right-click on kde desktop in Knoppix and choose 'Configure Desktop' -> 'Behavior' I not that the flag 'Display devices on desktop' is not selected, but I have all devices displayed on desktop anyway. How do Knoppix put device icons on desktop without using the 'Display devices on desktop' flag ? (My customization uses that flag to display device icons on desktop).


P.S. I have recycled 'rebuildfstab' of knoppix 3.2.
My 'mount' displays this:
/dev/hda1 on /mnt/hda1 type vfat (rw, nosuid,nodev,umask=000,uid=1000,gid=100)
/dev/hda5 on /mnt/hda5 type ext2 (rw,nosuid,nodev)

Thank you
Jack
