My understanding is that up to recently, the recommended procedure for repairing
RA81 messes was to reformat them in the field.  However, now the preferred
procedure is to replace the HDA and send the old one back to the factory.  The
factory has a machine that looks for weak blocks by playing with the voltages
applied to the heads while it reformats the disk.  The result is a more reliable
HDA.
