Disk usage discrepancy?

Hi i have a problem with storj. My harddisk is full. Storj uses there 17TB but in the node it shows that it uses only 9 TB , 4TB are free and 68GB are in the trash. There seems to be data on the disk which is no longer calucaleted in the node but uses disk space. Is there a way to clean it correctly?
In the past had this problem https://forum.storj.io/t/error-migrating-tables-for-database-on-storagenode-migrate-v57/26205. I have deleted the bandwidth.db include file(s) with .db-shm and .db-wal extensions.
