Display/Alter Sector Service Aid
This service aid allows the user to display and alter information on a disk sector.
Care must be used when using this service aid because inappropriate modification to
some disk sectors may result in total loss of all data on the disk. Sectors are
addressed by their decimal sector number. Data is displayed both in hex and in
ASCII. To prevent corrupted data from being incorrectly corrected, the service aid will
not display information that cannot be read correctly.
Diskette Media Service Aid
This service aid provides a way to verify the data written on a diskette. When this
service aid is selected, a menu asks you to select the type of diskette being verified.
The program then reads all of the ID and data fields on the diskette one time and
displays the total number of bad sectors found.
