unix: continue cp when error occurs?

I have a directory with around 50,000 .jpg images. Let's call this directory "imageDir", and the empty directory I'm trying to copy to "outputDir".

when I execute:

cp imageDir/* outputDir/

around 30,000ish images through I get:

cp: cannot open `imageDir/234235.jpg' for reading: Bad address

(this does not always occur on the same file) and then the copy operation will cease without copying the rest of the files. I tried adding the -R option after reading that it would continue the copy even if errors occurred:

cp -R imageDir/* outputDir/

but this did nothing to solve my problem.

Is there some sort of limit to the number of files you can successfully copy at a time? Why am I seeing this error, and how can I solve it? (if it happened for just photos here and there, I'd be fine with it as long as it completed the rest!)

Additionally: this is using Cygwin on Windows 7. Thanks!

Looks like an issue with Cygwin to me. Since you said it happens randomly, you might just want to try again when it happens. Here's a script (untested) that will do that:

#!/bin/sh
for i in imageDir/*
do
  cp $i outputDir/
  while [ $? -ne 0 ]
  do
    cp $i outputDir/
  done
done
