Hi, I got a problem with my SanDisk Memory Stick PRO Duo, it used to work perfectly fine until one day it suddenly stopped working, none of my friends psps will read it niether my one and my card reader usb won't read either it just says no card in there and i tryed my friends computers. it has some save files that i got really far on.
The memory stick has obviously failed. They are pretty fragile, especially if you keep moving them from device to device. If you did not back up the save data before now, then it is gone. Nothing can be done to recover the data if the card cannot be read.
