Just an FYI regarding invoking fsck.  Fsck starts
by analyzing the type of file system on the device
you specify then calls another program to do the
actual work.  For example, on my system there are
these entries in /usr/sbin.

fsck
fsck.btrfs
fsck.cramfs
fsck.exfat
fsck.ext2
fsck.ext3
fsck.ext4
fsck.fat
fsck.hfs
fsck.hfsplus
fsck.minix
fsck.msdos
fsck.ntfs
fsck.vfat
fsck.xfs

While the specific fsck versions can be invoked
directly it is seldom necessary.

Fsck also checks that the options you specify
are valid for the FS type on the device.
