question for ppl who had to send ps3 back to sony

i upgraded my hdd i am going to take it out because i dont want to lose it should i put the old drive back in or send them it without a hdd

i sent back mine with the hdd and got in back with everything but mine was the default. I guess you could put back the original incase or you could send it like that but state you have an ugraded hdd so they would know and make sure you get it back.

but the old one back in, just in case :)
