are options supported by the generic fsck
The dosfs-specific fsck command checks that
the File Allocation Tables (FATs) are readable. At least one
FAT must be readable for fsck to proceed.

This command executes faster if it is not required
to autodetect file system types. If possible, specify

For directories, file size not being set correctly to zero.
For regular files, file size set to an incorrect byte count.
For long name entries:
check that the sequence numbers of the entries are in order
check that the checksum of all entries are the same
check that there is an alias entry with the same checksum
