- This file should explain the meaning of the various statistics printed by
- fsck or displayed in the 'Statistics' window of FSCK³: it would be better if
- you read the file MapExpl before reading this...
-
- Since FSCK³ supports interactive help, you can try to use it over the
- 'Statistics' window instead of reading this file.
-
-
- 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 wasted because of sector boundaries: 1261322 bytes (1.4%)
- This is the difference between the two previous values (ie. space allocated
- for files - space actually used by files).
-
- - 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.
