I succed to install Ubuntu 6.06 in my Mac Mini (I must used Ubuntu 5.10 on live Cd because it crashed when I try to install it on my hard drive) and I try Kfloppy and Kformat to make my version of KFormat. I think I would use some idea of Kfloppy but I have too much problem with the version which already exist to continue it. Kformat doesn't want to format something and it often crashed. I think I will rewrite a code from scratch but I will use some idea of these two program to accelerate my project.
