I have a Toshiba Satellite A-55 and it just recently crashed on me. I tried to use my systems disk but the computer keeps displaying "wrong disk". I checked the systems information and it's showing that my system model is a "Portable PC" not an A55. Is there anyway that I can get my computer to read my systems disk for A55 at my level? If so what should I do?

It sounds like you don't have all the disks required to do a recovery otherwise you wouldn't be getting the error saying "wrong disk". Consult your pc documentation to find out what is required to do a system recovery.
