["HKG RI-C /HUI, ADA" <external ada hui kuehne-nagel com>]

Dear all,

I meet a problem in installing Red Hat Linux 9. It's fine with first part of
the installation process, but when it come to start formating my harddisk,
it give me an error. I've choosed remove all partition and auto partition.

I have tired to install in text mode also don't work. The harddisk is new,
it is a 20G seagate IDE harddisk. Also i tried to format using a dos disk,
there is no problem. I don't know what's wrong, please help. Thanks.


Best Regards,
