a 2.5" SATA drive, and a tape-based hard drive caddy, plus 4 screws for it https://digipres.club/system/media_attachments/files/113/001/893/374/660/411/original/2ee1b2ee900ba402.jpeg
the hard drive was TAPED in? taped AND screwed? fun thing about the hard drive:it is mechanical and has NO PADDING! on a tablet! designed to be used by hospital patients who might DROP IT!
