Ok, which OS was installed on it before trying to install BSD? -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org] On Behalf Of Carsten Zimmermann Sent: Monday, May 03, 2004 1:03 PM To: Malcolm Kay Cc: freebsd-questions@freebsd.org Subject: Re: Partitioning fails due to drive geometry inconsistency Thanks for the answers so far. I tried to use the autocorrected values, of course. But I can't create a partition with them (as said: I was able to delete a NTFS partition w/o problems). When I try to write the partition table, sysinstall / fdisk catches signal 11. It seems fdisk is not able to write the partition data since the (now autocorrected) drive geometry is (still) not valid.
