My 32gb scandisk SD had the same problems, after using it a while it can't be read. Not to mention it is my 3rd copy. My 1st copy was bought from a local store which don't allow return/exchange (Warranty is valid but a lot of process in between), so i thought that i might get a bad/fake copy. So im force to buy another copy (scandik 32gb) at a big chain store retailer as it looks legit. After a while my 2nd copy get the same problem it cant be read or stated as blank SD card. Finally i bought my 3rd copy in Singapore airport in one of my trip, this time also scandisk 32gb but the android version. It works great for around 3 months until it died out yesterday!!! It is very frustrating!!
So guys if there is any solution pls post it T.T
