So to get rid of this error I had to completely wipe the drive with a drive wiping util. It was not as quick and easy as wiping the beginning of the drive. The raid controllers save their config at the end of the drive, and not exactly at the same spot, so thats why during the install it saw two 'formats'. I now no longer get this message, now the machine just seems to hang during the install. > I decided to replace Suse 10.1 with Centos 5.0 on my file server.
