DNS320 with 2x2TB Drives on Raid 1. Everything was working fine until I decided to turn on UPNP. It took about 3 days to complete and then I disabled it again. This is the only change I have made recently. All my shares have gone. Admin page is saying I have used 0% which was 85% - Where has all my data gone? I am trying auto delete software etc. but am I missing something. Same old I am feeling, I purchased for complete data backup (Raid 1) security - Erm, I am panicking - Photos going back years etc. etc. etc. etc. Please help.
