WD Drive Plus, portable HDD. Model no.: WDBZC0040BBK-WEWM. This does have 256-bit encryption, but I also never set up any password or anything as I mentioned earlier. It was exfat when I bought it and changed it to ext4 so I could use it on my Arch computer. Haven't had any issues til about a little less than a week ago now. I also always make sure nothing is moving or making sounds, etc. before I unplug and move things. No visible exterior damage, and nothing tinking around internally.
