Fiancée and I were playing the old 0.8.2 update and got us our Kerfur-0 son named Tofu. When the 0.9.0 update dropped we decided to take Tofu with us to the new save. Worked fine and all, Tofu reassembled and turned on just fine. Still lowkey creepy and just standing in the left hand corner of the base where we idled him.

We then tried to send him out with a floppy disk in hand to go and collect the reports for us. Tofu returned to us with with an empty floppy desk, he had thrown in front of the desk before we woke from our nap and scared the shit out of me specifically by watching us sleep. 
(we do not play together on a multiplayer mod (duh), I watch and he plays because I'm a pussy)

TL;DR: Our Kerfur-O returned with an empty floppy disk....... help?

you need to place the floppy disk in the computer move the hashs to the buffer then move the files to the zip disk they gave to do the server hash quest now, if therre is no data on the floppy to move to the buffer it might be a bug or the disk is bugged, also the floppy disks have a read/write limit of like 20uses, once they are used up they will not take data any more
