Somebody who really knows about this stuff needs to write some verbiage for the handbook. What I have read and what seems to work for me is that the geometry on currently modern drives is "virtual" as far as the OS is concerned and that you should go ahead and just slice and partition the disk and build your file systems. If it works, don't worry about the geometry messages. ////jerry > _______________________________________________ > email@example.com mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" > _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
