Oh dear. 3years worth of pictures. thats a loooooot of keep sakes.

im not sure if you would lose them or not,, but i would definitely burn your pictures to a disc to be safe. or buy one of those USB jump drive thingies an store them an other keep sakes on that.

plus its wise an always good to have your pictures an other keep sakes saved somewhere other then on your computer cuz your hard drive may die at any given moment an youll lose literally everything. or your computer extract a virus an not allow it to boot up leaving the only option to reformat an you lose everything that way.

i have learned this the hard way. i didnt lose 3years worth of pictures but it was very devastating none of the less.
