Default Chkdsk Sucks

There must be a program that does what chkdsk is meant to do and does it
better -- maybe with an interrupt option even.

Suggestions, please?

I'll even try one that runs in Linux.

Norton Utilities had one, but that was 15 or 20 years ago. Maybe they
still do.

You will find a lot of "noise" in a search on this
topic. I have yet to see anything remotely resembling
CHKDSK. Linux has ntfsfix and ntfsck, Tuxera and
Paragon sell NTFS file systems for other OSes. But
as far as I know, all this capability does is
"consistency checking". In some cases, Linux
sets the "dirty" bit, so that the next time you
boot Windows, the Windows CHKDSK will run at boot
time. (In football parlance, we call that "punting".)

Linux NTFS doesn't know how to deal with permissions,
so right away, it's a "half-implementation". For
which we're thankful. Nobody wants Linux to have
a full implementation (making Linux useless for
maintenance, like deleting things you cannot
normally delete).

Since Vista, Microsoft has been working on "self-healing".
This is not a scan as such. It's opportunistic.
If a file system issue is spotted on a directory currently
being read, a worker thread can be started to repair it.

http://blogs.technet.com/b/doxley/ar...ling-ntfs.aspx

fsutil repair query c: --- check the setting

Self healing is enabled for volume c: with flags 0x1.
flags: 0x01 - enable general repair
0x08 - warn about potential data loss
0x10 - disable general repair and bugcheck --- ouch!
once on first corruption

The commenter at the bottom of that blog page notes that this
leads to the file fragment being deleted. So be careful what
you wish for. The "general repair" could lead to file deletion
(if a file is a fragment and not really committed or something).

The availability of self-heal, has not changed my practice
of running CHKDSK here. I still do it occasionally. Even if
Windows says "I don't need to scan a partition", I still
scan it.

*******

The lack of availability of a complete NTFS spec, is
probably as good a reason as any, for utility companies
to not try to compete with Microsoft CHKDSK directly.
And since features of NTFS are at the driver level,
as well as in the OS itself, it's not like having
just the NTFS spec would be all that useful by itself.
It would be half of the story.

I think you'd want the source code for the existing
CHKDSK, to try to beat Microsoft at this game. And
you know the code isn't going to be commented. "Real"
developers don't write comments.

For NTFS CHKDSK is your best option


I've seen it perform some pretty nice recoveries.

While not a real (direct) replacement for chkdsk, Spinrite,
by GRC, is an excellent disk assessment and byte recovery
tool. It's currently a little dated, as it has problems
with the more recent, huge hard drives, but the author
intends to update it as soon as he gets his SQRL work out of
the way. Also Spinrite is not free--not even close. But
the license is very liberal, giving the licensee the right
to use the software on *any* machine, anywhere.
