Halog 356807 is wrong. Run 3778 is indeed in MSS with correct byte count. Don't worry. All files are going to MSS and my checking scripts logs all info and e-mails me with problems. As for the last 15 years.
Because of the concern I checked the recent activity. All is well.
Please do not touch or move the data files, nor copy anything to the data disks. Leave it all alone.
