try to take it on hdd saver service. when my hdd died they brang back 70% (lot of folder and filename lost, but the structure and files had themself)
one try worth!
and make archive, or if you have just few giga stuff, use dropbox!
(i try artchive weekly, not allways succeed, now at least monthly)
im sorry. when i had first hdd crash, i lost everything, i did not draw for a half a year.
