now provide for switching to an
alternate track when an attempt to do I/O on a defective 3340 or 3344 track
results in a track condition Similar recovery procedures have also
been added to three stand-alone
utilities: the DASD Dump Restore (DDR)
Service Program; Directory Service
Program (DMKDIR); and the
