1.) As far as I know, there is no real benefit or need to defragment a linux partition. Windows and linux use different filesystems.

2.) Don't know, other than to back up often.

3.) we'll need to know what your fstab consists of.

Please hit alt+f2 then type:

kwrite /etc/fstab

if you're using kde

or

gedit /etc/fstab

if you're using gnome

and copy and paste the contents of that file onto here.

Take Care,

Ian
