scorcho99 Posted February 25, 2022 Share Posted February 25, 2022 Some of my disks had some sensitive documents with personal info on them. The disks were not and are not encrypted. I deleted the files some time back. I'd like to assure they aren't recoverable in the case of theft, drive sales, etc. All the disks in my array are hard drives. From reading around, what I should have done was used shred to overwrite them instead of just deleting them, but I wasn't thinking that far ahead. So I was thinking that filling the empty space on the disk with zeros would accomplish the same task, albeit not very efficiently. Would something like this work? Or will unraid interfere with this in some way I'm missing? dd if=/dev/zero of="/mnt/disk1/filler" bs=10485760 dd if=/dev/zero of="/mnt/disk1/filler1" bs=1 rm /mnt/disk1/filler rm /mnt/disk1/filler1 Quote Link to comment
