SDS: Fixed head disk addressing corrected when start new sector

Browse source 
rad_adjda was setting sba=0 at a sector boundary, which did not reflect that the first 12-bits of the sector have already be read or written. Must set sba=1 for proper addressing.

Removed superfluous end-of-line spaces from file.
