File Scan utility

[Guest]

Folks:


Looking for a utility that can scan through files for physical integrity,
CRC errors, etc then report back.
CHKDSK.EXE works well for the entire disk. But sometimes I just want to
focus on a few files.

Trying to burn some large files and encountering some mysterious errors.
Thought I would first check file and
disk integrity, before burning.



Thanks,
Jo.

CRC errors are caused by defective media, not file corruption.

There are lots of CRC calculator freebies around the 'net but ...
without first knowing what the CRC SHOULD BE, it won't do you
much good. You would have to run the CRC app on the files when
you know they are good, then you could later on do another CRC to
see if anything changed, but ... it doesn't sound like you have
those.

Ah; just realized something: You may not understand what CRC
means or is about? It's just a mathematical calculation
performed on the data and position of the data within a file that
creates a unique number related to the data in the file. That's
a crudely simplified definition, of course, but it should
suffice.
Changing a bit in the file will create a different CRC, thus
telling the user that something has changed.
Without having that initial CRC number, running another CRC on
a file cant' tell you anything.

Now, if you had a copy in archive maybe, and then your on-disk
copy, you could compare the CRCs on those to see if they are
identical files. If it was good when you archived it, and CRC on
both files match, then they are identical and unchanged.

CRC errors are caused by defective media, not file corruption.

Or bad file downloads.
