My 1GB M2 Memory Stick Was Crushed

When I want transfer songs to my hp,
I connected my hp into laptop,
But laptop cannot detect my memory stick already=(
I thought is the hp problem, then I took out memory
stick and try inserted it back to hp.
Who know...My hp still failed to detect it and
keep asking me to format my memory stick=(
I felt worry because there were a lot of memorable
photos inside memory stick...T____T
I really don't know what should I do.
