Gateway Repair

Hi all,

I recently sent and received back my laptop to Gateway to be fixed (the lid's hinge cracked). They did an excellent job but they decided to reformat my harddrive or give me a new one.
They asked me first if I backed everything up, so I backed up some, but not all thinking that its just a lid replacement, why owuld they format. I torrented this program that's supposed to recover stuff that's been reformated but it only detected stuff from the current system.
I'm pretty sure they just replaced my harddrive, so does anyone know if by any chance that they would keep the old ones or if I could get it back to just get some data? (photos)

I sent it to Decision One (I'm guessing they're gateway's computer fixers in Canada)

Jam it back in, in the dark.
