I'm pretty sure the oem is not hooking up every rma drive and looking for files.
"well, new rma drive? Let's pop it in the USB caddy and see what's there... Hmm, some files... jpgs... Mpegs... Oh look. Pdfs with embedded viruses. Good thing we didn't connect this drive to... Oops"
They're sending that thing straight to the industrial degausser and then certification for possible resale.
I never understood the "gotta have 'em all" mentality of mp3 collecting.
"Hey! Check out my massive collection of bitrate/dynamic range/frequency range -decimated music. I don't need CDs anymore."
