I use a Sandisk SD HD card(Fat32) with an adapter. When I try to put anything onto it it says "this disk is write-protected" I've had this card since X-Mas and had no problems with it before. Someone pleease help!!
Sometimes if a MicroSD becomes corrupted or starts to fail, it will start to be flagged as write protected even when it is not really. You can either try a new adapter, or you will have to buy a new MicroSD (unfortunate, but true). You should backup what files you can right now incase the it is corrupted so you won't lose your data. You should also first check to make sure your MicroSD Adapter does not have a Lock switch on it. Some MicroSD to SD adapters have this lock, and it is very easy to accidentally switch on.
