I have a Buffalo LS-WX6.0TL (Rev 1.0) working as a home NAS - it has twin 3TB drives in RAID0 It behaves perfectly but it's very nearly full so I've taken around 800GB of data off simply by moving it across to another SATA drive as an archive.
Despite that the free capacity of the NAS obstinately refuses to change and shows just 300GB free (unchanged from before I started off-loading files).
I've disconnected it, reconnected it, run Buffalo's own web interface checking tools, shouted at and threatened it, yet I cannot get the space I should have created by moving the data to show up.
If I add files to the NAS the available space continues to reduce (!)
What am I missing here? Is the array damaged somehow? Any non-destructive repair suggestions? I'd rather not move 5TB of data (it is backed up to a separate Raid10 but it still means a lot of time to put things back).
