I built my own Freenas box and it's nearly full. I'm installing the files onto an external hard drive for archival use, and I want to wipe the files on the NAS. But after ordering it to delete files--I do this in Windows Explorer--the data usage indicator says the NAS remains nearly full. I've backed everything onto the external drive. I just want to erase what I've got on the NAS and start refilling it. Is this happening because it's a RAID 0? Or what other reason could it be? I need all the help I can get! Thanks!
