Probably the best sector editor and all round disk
utility we have ever come across with a set of documentation as large as
the program and which itself is a goldmine of information about the
structure of disk files and how to properly use a sector editor and
other disk utilities. There are several sections to this utility -
DIRECTORY, SECTOR, VTOC, ASSEMBLY LANGUAGE and UTILITIES. Directory mode
gives full information about the directory of a disk including the
starting sector, length and status of each file and allows you to lock
or unlock files or recover deleted files. Sector mode allows you to
check and amend any sector on the disk, move sectors to other parts of
the disk and find hex or ASCII strings. VTOC mode displays a bit map of
the disk and allows you to edit the map as well as showing the location
on disk of the last traced file. In Assembly Language mode, traced files
can be disassembled to the screen or a printer and files can be modified
as you go. The Utilities allow you to format in single or enhanced
density, zero sectors, check drive speed, verify files and make sure
that the VTOC on your disk is correct. It is impossible to mention all
the detail of this program but the very extensive documentation takes
you through every feature step by step in a tutorial manner and the
appendices present much useful information on disk structure.
