9. Incomplete deletes (deleted files with non-zero ‘name
length).
10. Incorrect directory storage types.
11. File and directory block counts.
12. File and directory dates and times.
In file names (point 5) lower case characters are converted to
upper case, high bits are stripped, and other illegal charac-
ters are replaced by periods, illegal dates and times are
zeroed.

upon:
13. Blocks used by two or more files.
14. Block number out of range (past volume size).
15. Unknown storage types.
Some errors result in files or directories being skipped over. You
will be told if this occurs. It happens because of information
damaged in such a way that the situation cannot be handled, or

is invalid.
Some block read/write errors cannot be handled and will result in
termination of the program.
Sometimes in the error printout you may see a directory name
printed twice. This indicates the correction refers to the direc-
tory “header” rather than the “parent block”.
MR.FIXIT will also look for blocks that are marked used on the
volume bit map but are not used by any file. You will be given
the option, in Fix mode, of releasing these blocks. Sometimes
areas of a volume are marked off without belonging to any file
and in this case you should not ask that these blocks be freed.
Examples are the UNODOS area on a Unidisk or a Pascal area.
As a general rule, if the number of blocks indicated as being
marked, but unused, is large, then you should assume that they
