Xcopy Continue (/C) switch

Folks:



The Xcopy (Xcopy.exe) command has a "/C" as one of its switches.
"C" means continue copying a file even if errors encountered."

I am trying to copy a few 1Gig size files from a DVD to a hard disk. So far,
3 of these files have been successfully copied.
The fourth file keeps giving an error message, half way through the copying
process:

************************************************************
Cannot Copy <Filename> Data Error
(Cyclic Redundancy Check)
************************************************************

By the way, all of these files I can play using Windows Media Player or Real
Media Player without problem at all.
I thought Xcopy's "continue" switch would bypass any CRC errors.


Appreciate some light on this problem:

* Why is it happening ?
* How can I solve it ?



Thanks,
Jo.
 
So are you trying to copy from a DOS window (e.g.
%SystemRoot%\system32\cmd.exe) rather than copying from Windows? If so, I
have to ask why? But it's late where I live and I am very tired so perhaps I
am missing something here.

A CRC error indicates a serious hardware error that causes
the operating system to terminate the current application. You
received this answer to your previous post on the same subject
and nothing has changed since then.
 
You posted this to newsgroups for many different operating systems and
didn't mention which one you're using. If you're using Vista, try dragging
them over and skip the XCOPY command. There's no reason to use XCOPY for a
simple operation like this.

XCOPY allows you to control things (like the /c switch) that you can't do by
dragging and dropping. Take a look at /a /o /x for example.
 
I believe the /C switch on Xcopy, when copying multiple files, allows the
copy to keep copying additional files even if one or more files fail (instead
of aborting on the first error).
 
Exactly my point. Using xcopy allows you to do things that drag and drop
can't do.

Thanks for your many interesting comments. Here is the solution that worked
perfectly for me.

There is a very powerful shareware tool called AnyReader (www.anyReader.com)
.. This tool has the ability to retrieve
material from all sorts of damaged media. It is can easily:

* Copy files from damaged drives
* Copy files from scratched/damaged CD/DVD
* Copy files across an unstable network
* Merge broken files

I was able to extract a 1 gig file from a DVD that prevented regular copying
due to CRC issues.
Now to document this solution for possible future use or to help someone
else.


Cheers,
Jo.
