Since its 2017 edition, Windows 10 has stopped mirroring $MFT to the
full size of $MFTMirr leading to mounts of partitions with big clusters
to be rejected because of mismatches. With this patch, only 16 records
are checked, though mirroring is still done for all records in $MFTMirr.
The bad cluster list may be updated in ntfsresize and ntfsfix. Though
technically it is organized as a sparse file, Windows does not set
the sparse flags. Do the same to avoid problems with third-party
packages.
When used with the "no-action" option, the test for self-located MFT
still reported the partition to have been repaired. Adapt the report to
only tell repairing is possible.
When the unmounting of the partition fails after running ntfsfix, a
second try was attempted. This cannot be done and leads to more errors
because some essential records have been freed, so better quit without
making a second try.
The ntfsprogs used to return failure when option --version or --help
was used, and this has triggered complains from distribution packagers
who use these options in packaging scripts.
With this patch, success is returned (same behavior as gcc).
The MS_* flags originated from system constants. However the flags
passed to ntfs_mount were really unrelated to the system constants and
many new MS_* flags had to be introduced as different features were
added to the library. Those flags had no counterparts in any system
APIs, so using the same naming scheme is inappropriate.
Instead, let's namespace these flags similarly to what has already been
done in ntfsprogs/libntfs earlier. This avoids any possible conflicts
with system constants.
The values of the flags themselves are kept the same as earlier, so
backward compatibility is retained.
ntfsfix now checks and update the backup boot sector on the last sector of
the partition (instead of the sector next to end of the file system). After
an ntfsresize the file system generally does not use the maximum size because
of different roundings and required alignments in the resizing and the
repartitioning.
Clearing the bad cluster list was done by truncating $BadClus:$Bad,
this turned out not to be reliable because chkdsk does not adjust
the size of $BadClus:$Bad when declaring a cluster bad.
Under some rare and obscure circumstances probably unrelated to ntfs-3g,
a part of the runlist of MFT describes its own location, therefore
it cannot be loaded. This patch relocates the MFT extent to inode 15
to fix this. Note : chkdsk cannot fix it and destroys all the files.
When the normal boot sector is not usable, ntfsfix tries to use the last
sector as a boot sector replacement. This implies getting the sector size
and reading both full-sized boot sectors.
