What are the differences between Unix's fsck and Windows' chkdsk?

The internal structure of filesystems is totally different among each other, so different programs are needed for different filesystems. Even on UNIX/Linux systems there is a dedicated filesystem check program for every filesystem implementation (ext*, xfs, jfs, etc.)

Normally the initial command chkdsk/fsck checks the format of the underlying filesystem and then calls the dedicated check program.

  • xfs? jfs? are those better descendants of ffs than ext? Oct 27, 2011 at 17:30

    Different filesystems - but it would be too lengthy here (and the wrong subject) to tell you all about different filesystems and it is all on Wikipedia.
