Statistics calculation doesn't seem to progress

I moved my backup storage to a different disk, since then I don’t see disk usage on backups, and recalculating statistics looks stuck (for over 48 hours).
Should I wait a bit more? Is there anything I can do?

same for me, have you fixed it?

I am in the same situation. I’m on the latest Windows version of the URBackup server application pointing to a new NTFS drive. I created the migrate file and afterwards ran remove_unknown batch file per the documentation. Incremental and full file backups show unknown for disk usage but incremental image backups do show a value. I’ve ran the different batch files to cleanup and repair the database. I’m running Recalculate Statistics again and will wait overnight to see if anything changes. Any advice would be appreciated.
Thanks,
Roger
