Hello, I am looking for suggestions for a "ruggedized", self-powered enclosure for my 2.5" HDD. I am worried about wear and tear to the drive itself when I put it in my backpack and transport it from place to place. I don't care so much about external protection, as I do about "padding" within the enclosure. Ideally, I'd love to find the Otterbox of self-powered HDD enclosures Any ideas? Thanks!
