Duo v2 volume scan found and corrected errors

I purchased a ReadyNAS Duo v2 a few days ago and set it up with 2 WD30EFRX drives (these are on the HCL). The firmware version is 5.3.7. If the NAS reboots and does a file system check after a large amount of files have been written to it, error similar to the following occurs. I've tried doing a factory reset but this didn't fix the problem.
