I am having a problem with my microsd card,last night I noticed that my phone does not detect the memory card so I removed it and tried it in my computer but when I try to copy some thing from it ,It says parameters incorrect,pls help me all my important files are in that memory card.
Most likely the card is defective. You should contact SanDisk for a warranty replacement. Unfortunately, there’s nothing to be done about retreivinig your files fom the card, unless you want to pay a professional data recovery service a few hundred dollars to attempt to get them off the card (which isn’t guaranteed).
