|Do you have another computer that you could hook that toshiba hard drive up to? Preferably a newer desktop because you will probably need to connect it via sata. If you do, you can remove your hard drive from your laptop and hook it up to that second computer, that way you will use the OS on that other computer to mount your hard drive so that you can copy files back and forth.|
If you don't have a second computer, I would say take it into a shop. Most places will not have issues with pulling your hard drive out, slaving it to another system, and copying everything to your backup drive. They will charge you to do this of course, but preventing loss of data is worth the money.
