Destructive Surface Analysis

Use this option to accurately locate any bad tracks on a hard

disk, and to flag any bad tracks that are not flagged.

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

and then

Enter. You see

these messages:

Analyze Hard Disk

Read/Save/Write/Read/Restore/Read

check for all tracks...

Current cylinder is

nnn

As each track is checked, the cylinder number (nnn) 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, such

as the following:

Analysis finished.

Count of tracks flagged bad

Count of tracks with write, read errors =

Count of good tracks

= nnn

No write,

read error was

detected.

No data was destroyed.
