|Be aware that the Toshiba(and any other) factory reset\restore routine "will" erase all your personal files during the process. So hopefully you them all duplicated\copied to external media too.|
If not before go any reset\restore path... See if you can access them via Linus disk boot.
Typically ubuntu (ubuntu.com) is one to use. Download ISO, burn to dvd; boot with the dvd. It will load into RAM only, and will not load onto the drive (unless you opt to - I wouldn't advise that). The hard drive (if working at all) will then be a mere resource the Ubuntu OS running from within RAM. Thus you can locate and.copy your files to external media - typically dvd at least. Check the copies are ok on at least one other working system; then (labeled) keep safe... The data can restored the hard drive later. And wise to regularly cope (duplicate?) your file to external storage - just in-case you problems in the future (similar to, or worse than now...?)
