Just for my own sanity: if the drives had rear errors, those would be
logged by the kernel, right?
I did run hdrecover on all those drives and it completed on all of them
(I did that first before checking anything else)
Here's me reading 1GB from each drive at the 3.5TB mark:
myth:/sys/block/md5/md# for i in /dev/sd[defgh]; do dd if=$i of=/dev/null bs=1GiB skip=3500 count=1; done
