5.11 MR.FIXIT
P U R P O S E :
This program
is
used to test and attempt to repair data blocks on
your bard drive or floppies. The program allows you to choose
several types of testing to be performed. It also allows you to
print out a copy of the test results. You can and should use this
program even when you are not having problems. Often finding
a data block error early can mean important information can be
repaired instead of lost.
HOW TO USE:
MR.FIXIT has four modes: a Test mode in which nothing is al-
tered on the disk, a Fix mode which attempts to correct defects
found in the directory structure, etc, a Main directory mode
which attempts to reconstruct the main directory and a Bad
blocks mode which scans for bad blocks and, if desired, places
them in a bad block file. The Fix and Main directory modes are
very dangerous and can change a bad situation to a worse one,
so never use them without first using the test mode and never use
them without an adequate backup that you can fall back on.
The program tests and, if fix mode is active, fixes the following
defects on any ProDOS volume:
1. Header pointers of all active files.
2. Parent pointers and parent entry numbers of all sub-direc-
tories.
3. Backwards directory links.
4. Used blocks marked free in the bit map.
5. Illegal characters in file names.
6. Entry length (the program assumes this should be $27).
7. Number of entries per block (assumes this should be 13).
8. File count in each directory.
