Restoring Factory Default Image from Sony Vaio Notebook

Hello all.

I'm just wondering what I can do with regards to restoring from a recovery partition. I formatted my Vaio notebook a while back, and it essentially became stock Windows 7 with no 'Sony' applications and such. However, my hard drive only has 452 GB space available - and after checking, when I reformatted again relatively recently, I discovered that Sony's recovery partition was still there, even though the ability to restore Sony's factory default settings were gone, as I had removed the Sony Vaio Control Center or something of that sort, as I had done a fresh install of Windows.

Some drivers from the support website just don't seem to be working, and I really wish I had the original drivers and everything installed.

I'm curious as to how I can restore the actual original image - even though in Windows Explorer, Sony's partition is seemingly hidden.

I unfortunately did not make any recovery discs, so I'm a bit tight with options.

Thanks.
