Finally.
The new Harddisk is more than twice as large and makes a bit more noise.
Friday till Sunday was spent with reinstalling and copying the backup data. I have learnt several things, e.g. the difference between Vim.app and gVim.app or how to disable the useless Spotlight feature (the root of all the sudden slowliness).
I have left 10G empty, if someone finally ports ADB-Keyboard support to FreeBSD, i am installing FreeBSD on the last partition.
Other news, last week university started, and i really missed my notebook, while trying to get used to my new timetable..
