SMDCRC - a non-destructive, read-only test of all
tracks on a SMD disk.
PARAMETERS:
Parameter 1 = disk unit to be tested (Default: unit =
0) • Th era nge 0 f val i dun i t n urn be r sis 0 - 3.
DESCRIPTION:
Before the read test begins, SMDCRC goes through the
start-up sequence described in the INTRODUCTION TO SMD
DIAGNOSTICS. Any errors during that procedure cause
SMDCRC to abort the test.
For each repetition, SMDCRC reads the entire disk track
by track. All READ packet commands are issued in
interrupt mode. For each error encountered, an error
message is displayed and logged to SADIE, and error
status bits are tallied. At the end of each repetition
of the test, SMDCRC displays a lap summary table, which
shows a cumulative tally of error status bits and
packet commands issued to the SMD controller.
SMDCRC repeats the read test n times, where n is the
value in the #REPS field of the test line. If REPS=O,
SMDCRC repeats until the user aborts the test.
ERROR MESSAGES:
SMDCRC displays error messages with the format
described in the INTRODUCTION TO SMD DIAGNOSTICS. Dur-
ing the read test, the possible contents of the Opera-
tion Field of error messages is: READING TRACK.
NOTE
SMDCRC reads entire tracks. The disk address
an error message is the address of the first
tor on the track where the error occurred.
error may have occurred on any sector on
track.
