I had been running a Western Digital 4TB My Cloud drive on the home network for the last 10+ months noo issues. Then some of the external mounted drives to the NAS keep dropping just this last few last weeks. So just did a soft reboot to the system an wonder of wonders it reformat all of it 4TB !!!! Many family pictures, research pic's and my model collection gone in 60 seconds! (NAS = Network Attached Storage https://en.wikipedia.org/wiki/Network-attached_storage) Hear my BIG gasp at this point. I strip the hard drive from the enclosure ran to my Linux PC plugged it in and ran a disk recovery program for the next day and half. Now I think i have recovered most of it(?) but I now have weeks of sorting and renaming files ahead of me. Now you may ask why did share this with all of you, to remind you all to have a good backup of all your precious data files so you do not find yourself in my shoes.
