UNMAPPED SOFT ERROR(S) ON CYL# cccc, HEAD# hh
HRM
The diagnostic can flag only one sector on a track
as bad. The presence of more than one soft error
or one hard error and one or more soft errors
means that one or more of the soft defects can not
be flagged. This is not a fatal error, but
unmapped soft defects may degrade system perfor-
mance.
BAD TRACK--MORE THAN 1 HARD ERROR ON CYL# cccc, HEAD# hh
The diagnostic can only flag one sector on a track
as bad~ The presence of more than one hard error
means that the track is bad, and hence the disk is
bad. The cylinder and head numbers of the bad
t r ac k rep 1 ace "c ccc" and "h h" (d ec im a 1) .
LAP SUMMARY:
At the conclusion of the re-format step, SMDFMT is fin-
ished formatting the disk. It displays the lap summary
table of commands and errors described in the INTRODUC-
TION TO SMD DIAGNOSTICS before exiting or repeating the
format sequence.
SMDFMT follows the lap summary table with a list of all
defects. For each defect the cylinder, head and sector
numbers are given as well as the severity (SOFT or
HARD) and whether the defect was mapped or unmapped.
NOTES:
SMDFMT does extensive surface analysis in an attempt to
find all defects on the disk. This analysis takes
time, and the time depends upon the number of scans
indicated by Parameter 2. It is recommended that the
number of scans be at least two. SMDFMT will take
apprOXimately 2 hours to format an 80 Megabyte drive
with 2 scans.
