This is causing file corruption on the underlaying file systems as well. I can copy a group of 100 100mb files and then do a md5sum on them and 1-3 will be corrupt. If this is a drive that is bad is there anyway to run a report on the count per drive that these mismatches occur. I have run smarttools test and do not see one drive that stands out to be causing errors. Could something else be causing these errors?
