AUTHOR
efsck is based on fsck (8) written by Linus Torvalds <torvalds@cs.helsinki.fi> for the minix file system.
Remy Card <card@masi.ibp.fr> has adapted it for the extended file system and is maintaining it.
Wayne Davison <davison@borland.com> has contributed lots of nice features.

BUGS
There is no support for a directory lost+found.
When a mounted file system is checked, super block informations are modified on the disk and not in the memory copy.
Please report bugs to the author.
