piping errors to a file

[Ardeaem]

I've got some problems with my file system that I won't go into, but what I'd like to know is what files can't be read. When I do

du /foo -h

I get a list of all the files, and size, in foo. But I also get an error whenever a file can't be read (Input/Output error). When I do this:

du /foo -h >file.lst

only the good files get listed. Is there some way to get the errors all in one file? I'd like a list of all the files that elicit IO errors.

Thanks.

du /foo -h 2>file.lst

The 2> redirects standard error output to the file.
