A non-braindamaged format program would only mark the bad sectors as bad provided you aren't using firmware sector sparing (whole tracks are normally marked as bad when there are too many bad sectors for the firmware. >The controller is an HP special.

Don't use WD sector sparing if you can help it. Disks with localized areas of dense bad sectors can be handled with bad144 by not putting FreeBSD partitions over those areas. Bruce
