This means that the boot block has been corrupted. DiscKnight can cope with
this if you know the parameters it was formatted with. You can find these out
using the !PowerMgr information display for the drive. Click on the advanced
options button, and enter the tracks / heads / sectors per track values into
the fields, and DiscKnight will then search for the map and rebuild the
bootblock.
