You wish to have "Reiser-FS".

Reiser-FS is a "journaling FS" that is "robust" so the fschk
is done in a few seconds on the bigest Gigabyte disks:
Simple said: It just checks if the the journal entries are uptodate.


Little background info:
The general problem is, that the FS holds a lot of infos
in RAM. For example which sector are free or which are allocated-
If those infos are not written back to disk and belongs to
directoy infos, the complete disk contens may become useless
if the next time is written in the area. Reiser-FS garanties, that
at least the directory structure will always be intact.

It is absoletly NO good idea to disable fsck!

DOS had that once. You know the story!
Today MS has added a fsck to their "DOS with GUI" that
runs automatically, when the PC had crashed.
