This is not controlled by one of the standardized SCSI-II mode pages.
Either by jumpers or some vendor specific mode page.

Yes and no:
a) scsiinfo does allow access to all mode pages worth noting.
b) reassigning bad blocks should be done by the disk itself. No tool is
required (except scsiinfo to enable it).
c) I just wrote scsiinfo 1.7 which includes a low level formatter and
allows you to add own defects. I didn't check, I dunno if it was moved
to a publically accessible dir ion tsx-11.mit.edu or
sunsite.unc.edu already though.
