If you have the original disk and can mount the filesystem then do this:
create a script like this and call it say /dir/testcatfile:
cat $1 > /dev/null
RC=$?
if [ ${RC} != 0 ] ; then
echo "$1 is corrupt"
fi
chmod +x /dir/testcatfile
Then do this:
find /tmp -type f -exec /dir/testcatfile {} \;
each file it gets an io error on will print out a message.
This only works if you still have the original and can mount it as it
relies on the disk returning io errors on the original disk.
