I'm receiving the error code 0xa0008703 when trying to backup to drive. It is failing on the capacity check status. It shows my online append capacity is 1,023 MB, but I have 80 GB free space on that drive. Any tips as to why it doesn't see the available space. It was seeing 0 MB available until I ran a backup of one file (1 mb). I did this just so I would be able to try a test run.
