WARNING: If any errors occur during this check, all data on the track that produces the error is destroyed. For this reason, if you think that an unflagged bad track is causing trouble, first run option 4, Non-destructive surface analysis, to check the disk surface.

This test operates by a complex process of writing, reading, and verifying information on every track of the hard disk, except for tracks that are already flagged as bad tracks.

To start the test, press 3 and then Enter. You see these messages:

Analyze Hard Disk

Read/Save/Write/Read/Restore/Read check for all tracks. . .

Current cylinder is xxxx

As each track is checked, the cylinder number (XXXX) counts down to zero. When the analysis is complete, the program displays a complete report on the status of the disk, including a table of unflagged tracks that produced write, read errors. For a hard disk with one flagged bad track, a display like this appears:

Analysis finished.

Count of tracks flagged bad

Count of tracks with write, read errors Count of good tracks

No write, read error was detected. No data was destroyed.

Press ENTER to return to the menu.

=n

=n

=nnn

If the program finds one bad track that is not flagged, the summary would show one track with a write, read error. The report is then followed by a table like this:

Write, Read Error Tracks =:=====IE=:=II::==13E::=IL:=

Cylinder Head Cylinder Head Cylinder Head Cylinder Head

237 2

Confirm to register the tracks in the Write, Read Error Track Table as bad tracks.

Do you want to register the error tracks as bad tracks (Y/N)?
