My nephew destroyed the hard drive cable in a Toshiba Portege R600 laptop when attempting to replace the drive, and so is trying to find a replacement cable (as per the photo below). Can anyone advise where he would find one, or does anyone have such cables they're willing to sell? Apparently, he's also looking for the same cable for Portege R500s not sure if it's the same one?).

He's needing the laptop to run speaker design software for a high-school project, so it's a fairly mission-critical item!

Thanks for any suggestions.
