This file should explain what the various statistics printed by fsck mean:
it would be better if you read the file MapExpl before reading this...
The value printed below are just an example (actually they are taken from my
84Mb HardDisc...).
- Number of shared fragments: 1720 (738 contains a directory)
This is the number of the map blocks (see MapExpl file) that are actually
occupied by small files that can share sectors instead of a whole file.
- Wasted sectors in shared fragments: 3964 (2029568 bytes (2.3%))
This is the number of sectors that are wasted because the small files that
could share sectors (see above) actually don't share all the possible
sectors with other small files (see MapExpl again). As you can see there
are quite a lot of wasted sectors on my HD!
- Directories bigger than the minimum size: 155
For some obscure reason some directories are bigger than their natural size:
the extra size can be shared with other files, so you don't have to worry
about this.
- Fragmented files: 13 (8 must be fragmented)
This is the number of files that are fragmented over several map chunks. On
my HD only 13 of 4716 files are fragmented: RISC OS seems to be very good
at keeping files in a single chunk! Moreover, 8 of these 13 files must be
fragmented because they are bigger than the size of a single zone.
- Total space allocated in map for files: 73865728 bytes (83.9%)
This is the amount of disc space that is allocated to files (including
directories). The space wasted because of shared map chunks is NOT
counted here (since it can still be used by other files).
- Total space used by files: 72604406 bytes (82.4%)
This is the real space used by files and directories. This is less than
the one allocated in the because of the sector boundaries.
- Space lost because of map organizations: 1261322 bytes (1.4%)
This is the difference between the two previous values. It should be
probably called "Space wasted because of sector boundaries". This
could be amended in future versions...
- Defects: 0 (0 bytes (0.0%))
No comments needed...
- Space used for map/root/bootblock: 93184 bytes (0.1%)
Just what it says to be...
- Files: 4716 (71092982 bytes (80.7%))
Number of files and space used only by them (ie. no directories). This is
the same result that can be given by 'Count'ing the whole disc.
- Directories: 738 (1511424 bytes (1.7%))
Number of directories and space used only by them (should be number of dirs
multiplied by 2048).
- Total used space: 75988480 bytes (86.3%)
- Total free space: 12091904 bytes (13.7%)
The same given by Free.
