fsck.cpm - check a CP/M file system
fsck.cpm [-f format] [-n] image
fsck.cpm is used to check and repair a CP/M file system. After reading
the directory, it makes two passes. The first pass checks extent
fields for range and format violations (bad status, extent number, last
record byte count, file name, extension, block number, record count,
size of .COM files, time stamp format, invalid password characters,
invalid time stamp mode). The second pass checks extent connectivity
(multiple allocated blocks and duplicate directory entries).
fsck.cpm can not yet repair all errors.
Use the given CP/M disk format instead of the default format.
-n Open the file system read-only and do not repair any errors.
RETURN VALUE .
Upon successful completion, exit code 0 is returned.
Any errors are indicated by exit code 1.
/etc/cpmtools/diskdefs CP/M disk format definitions
image: used/total files (n.n%
non-contiguous), used/total blocks" No inconsistencies could be
found. The number of used files actually is the number of used
extents. Since a file may use more than one extent, this may be
greater than the actual number of files, but a correct measure
would not reflect how many files could still be created at most.
A file is considered fragmented, if sequential data blocks
pointed to by the same extent do not have sequential block
numbers. The number of used blocks includes the blocks used for
system tracks and the directory.
