I have a Dlink DNS 323 NAS (network attached Storage) with 2 1TB HDD's. I had a folder with over 400GB of video files in a folder names movies. A few days ago the folder disappeared. I did not delete it and I've checked show all hidden folders. If I do a search of the drive nothing shows up either. Where is gets stranger is if I try to create a new folder named movies it will not let me name a folder that. All of the data seems to be there when I look at drive capacity under properties.
