This is typical of BSD incorrectly determining the translated geometry of a drive, then using that geometry to multiply a sector number from the C/H/S values in the partition table -- the resulting sector being off the end of the drive. You should run pfdisk.exe under DOS to determine the geometry. You need to run it off the DOS from the hard driver (for sure) and off a floppy (for crosscheck and to supply us wuth more info).
