Ok guys, I formatted the drive last time, and started downloading all of my videofiles again. Today I moved the NAS the clean it, and when I put it back together, I didn't put the 6TB drive in deep enough, so I booted the NAS; saw the disk wasn't connected and I turned it off, pushed the drive completely in, and booted again. When I did so my 6TB WD RED NAS drive was "empty" again.
For some reason as soon as a drive gets disconnected, the OS remaps the shared folder to another drive, which empties it.
So once again, the drive shows 600 GB used, which are my video files, but the OS shows the video folder as empty. When I put the drive into windows, it shows me 100% free space. I'm sick of Synology at this moment.
any advise?
