I have had a sandisk cruzer pop for about 3 years now and all of a sudden it has lost all its volumes and partitions and i cant put more back on it, it comes up as being plugged in on all pcs i plug it in on though. Please help i need it for school work. It says its empty and has no files on it but for some reason with microsofts own diskpart it wont let me create a volume or partition on it? And in disk management it comes up as not initilaze but with the button to initialize blurred out.
I have tried on latest mac OS X and windows 8.1
Please someone help me fix this problem or tell me wether it is faulty because it is still under warrannty
