Which form factor (size) drive/SSD in VPCCB15FD?

Hi everyone:

I need to replace the hard drive/SSD in a friend's VPCCB15FD. I tried calling Sony but they either refused to help or "accidentally" hung up on me. Nothing is mentioned in the spec sheets, the manual, nothing.

Can anyone tell me what form factor (size) drive this machine takes and whether the original was a spinning disk or an SSD?

Thanks
