HRM
Zilog
o dma = timeouts waiting for DMA complete
o oc = timeouts waiting for drive on cylinder
o sclk = timeouts waiting for Servo clock
o dclk = timeouts waiting for Data clock
o mark = timeouts waiting for Sector/index mark
o isnc = timeouts waiting for ID sync
o dsnc = timeouts waiting for Data sync
Tallies of other packet command errors, including:
HRM
o TOTAL = number of other packet command errors
o init = initialization errors (SMD controller reports
it does not have complete Dispatch Table
address and/or Interrupt vector.)
o so = sector overruns
o me = memory parity errors
o sel = select errors (0 or multiple drives)
o ct = byte/sector Count errors
o rze = rezero errors (rezero did not clear a fault)
o ae = address errors (odd address parameter)
o ofl = pack overflows
o pf = power-fail detected
o snf = sector not found errors
o wpv = write Protect violations
o inv = invalid Packet commands "reported by SMD cont~oller
o unk = unknown ending status code returned by SMD
controller
G Tallies of errors detected by the diagnostic, includ-
ing:
o TOTAL = number of diagnostic detected errors
o cmp = compare errors encountered by the diagnostic
when comparing two buffers
o htrk = the number of tracks with more than one hard
defect (only SMDFMT will report this)
o strk = the number of tracks with soft defects that
cannot be flagged as bad, because there are
multiple soft defects or there is a hard defect
that must be flagged as bad (only SMDFMT will
report this)
o resp = SMD controller not responding errors (polled mode
commands only)
o sto = SMD controller timeout -- controller did not
interrupt within expected time (polled or interrupt
mode)
