At least until the controller shorts and your forced to take it apart, to salvage the drive. I use to stick to wd ebooks and passports because they were always on sale for super cheap at my local store. ($99 USD most I've ever paid all 1.5tb+ ) Out of the 9 external drives I've purchased over the years, only 2 still attach through their original equipment. And only 1 is still in it's case. Switched to a dual docking bay a while ago. Now I buy "externals" for even less, as I just purchase a bare drive. Little stickers on the drives, tell me which drive has what I'm looking for. I will give em, every single one of those WD drives is still alive n kicking despite some of em being used as beer coasters for awhile.
I don't use externals with my boxes. Anyways, that passport has a 2.5" in it, meaning save yourself the trouble, take it apart now, and swap it with the hd in your RE box. You'll probably want to after you notice they don't have the same red hue. (I'm a pessimist/troll. Honestly have no idea to it's color)
