Disk usage discrepancy?

Thank you for the replies. I have looked at different threads, but there is very little conclusive info on the matter. If it is a software problem on the side of Storj, an announcement in easy to understand language would be appreciated. There is a thread on a problem with garbage collection and I assume it is related, but for someone not familiar with all the technical matters, it is really hard to understand what is going on. If this is a problem that affects many SNOs, it would be nice to have information from Storj team acknowledging the issue and with a road map for solving it. Otherwise we spend a lot of time reading through forum posts (and asking questions) without finding any solution.
