Conditional Format (Normal)
Use this option to format the hard disk. All flagged tracks are
marked so that they are never used.
To start the Conditional format, press 1 and then Enter. The
program starts to scan the disk to find all tracks flagged as bad,
starting from the innermost cylinder of the disk. During the
scan, you see the number of the cylinder the program is
currently checking. For example, if you have a hard disk, the
first messages you see are:
Format Hard Disk
Scanning for flagged bad tracks...
Current cylinder is nnn
When the scan is complete, the program displays
information about the condition of the disk, like this:
Scanning finished.
Count of tracks flagged bad
= n
Count of tracks with other errors =
n
Count of good tracks
= n n n n
