corrupt memory card no media found error

[solarflarex]

I had my tp2 fill up the storage card while taking a video. said it had 1mb left. i tried copying files to my computer and got an invalid argument error. rebooted phone and card is not detected. no backup things detect the card. windows does but doesn't show any size. windows disk management sees it but no partition. i want to save my data and am sure this is just something to do with corrupt fat. I tried searching and searching found an hp utility that allows me to format, but once again i dont want to lose data on my card. can anyone point me in the right direction?
