This can be fixed by changing the starting C/H/S values in the partition table. The ending C/H/S values should also be changed. The values can be changed using FreeBSD fdisk and accepting the defaults for almost everything. Enter the new geometry if the original geometry is wrong, and reenter all the offsets and sizes with the _same_ values. fdisk will compute the new C/H/S values. Don't try this unless you have a full backup or are used to running FreeBSD fdisk. -- Bruce Evans bde@zeta.org.au
