I use dd to test disks, and arrays. Give this a test. It may stop at the 2TB limit, not sure. My monster 14 disk array is only about 240G. time dd if=/dev/md0 of=/dev/null bs=1024k I don't think badblocks would detect bad block on an array. If one did occur, the drive would be failed and the array would continue. If your re-sync finishes, that really does test your disks since every block used by md is read or written.
