My old Apricorn External HDD was sittin’ around, held together by gorilla tape, lookin’ all sad and what-not. So I took the HDD and small board on the inside out of the case, and noticed they would fit nicely into a moleskine notebook, of which I have many lying around. So I cut the center out of all 80 pages of a Moleskine sketch book to form a cavity, you know like you would make if you were hiding a flask in a bible, and placed the HDD inside. And I recorded a time lapse of it too!
