Backed up external drive with 795 GB of files shows 620 GB when fully backed up

Dropbox backup seems unable to properly read file system of external ExFAT drive. Drive has 795 GB in use—but for first few days of backup, Dropbox believed drive had 50 GB of data, then 70, then 100...

Hey planimal, thanks for bringing this to our attention.

Let's see what we can find.

Is the drive constantly plugged into the computer?

Would you mind sending us a screenshot of what you see in your backups page here?

Thanks in advance.

Yes, but it's the same as described—regularly and everywhere proclaims "done" when backups are actually incomplete, as previously described. Even now, I don't believe it's correctly and fully backed up all drive contents that are reported as filesize 795 GB by drive itself. 

I had it plugged in for long (12 hour periods) over a course of days. I've just plugged it in again, but last backup remains about a week ago. Discrepancy in file sizes remains. I suspect if I went and made some dummy files in subfolders, I might trigger it catching a few more files, but it seems unable to survey the disk and file system to correctly ascertain for itself whether it's backed everything up or not.

    Thanks for the update and the additional info, planimal.

    Would you mind sending us a screenshot of your external drive's usage as well? The actual size of the files in the external drive, I mean.

    Thanks.
