A1200 new hard disk

How you tried to change the drive type first ?? If you don´t then HDtoolbox will read it as the last harddrive you have installed. It needs to read the new info about your drive. Then try a low level format and after that you can do the partitionning, but be sure that the first partition is not bigger than 2 Gb.

First thing you really need to do is stay calm !!! Don´t panic and don´t get angry !! Don´t throw the harddrive out of the window yet !!! Have you tried HDsetup yet instead of HDtoolbox Sometimes this works !!!
