Disk utilities, such as Quality
|
|
Software's BAG OF TRICKS, allow the
|
|
user to read and display the contents
|
|
of sectors. BAG OF TRICKS will also
|
|
allow you to modify the sector data
|
|
and rewrite it to the same or another
|
|
diskette. If you do not have BAG OF
|
|
TRICKS or another commercial disk
|
|
utility, you can use the ZAP program
|
|
in APPENDIX A of this book. The ZAP
|
|
program will read any track/sector on
|
|
an unprotected diskette into memory,
|
|
allowing the user to examine it or
|
|
modify the data and then, optionally,
|
|
rewrite it to a diskette. Using such
|
|
a program is very important when
|
|
learning about diskette formats and
|
|
when fixing clobbered data.

utilities called BENEATH APPLE DOS'

BAG OF TRICKS. See the page facing
