I have a sony pcg-k37 laptop and recently restored it to factory settings. Upon doing so, my DVD-RW (pioneer dvr-k14l) drive stopped working. It partially recognizes discs (files will show, but can't load them) or won't recognize discs at all.

Now I remember having this problem almost two years ago, when the laptop was only a few months old. I wish I could remember what I did to fix it, but obviously whatever it was, the restore reverted it. I checked and coulnd't find any updated drivers. Does anyone have any suggestions?

What version of Windows are you using?
