Error on Instalation

[Jonas Alexandre Nogueira]

Hi,

I'm trying to install YDL 3.0, but ever I begin format my disc and 
partition it, the instalation program break and show me that he can't 
proceed because a serious problems occurr on /dev/hde4.

I trying to partition from MacOS X (with the requires partitions ) and 
format that partitions during installation of  YDL, but a error on 
anaconda stop my installation. So, I don't know what I must do.

The machine where I try is a X-server 1GHz dual processor, first release 
without any periphericals except by keyboard and mouse.

Can anyone help me ?
