I have Win7. 64 Bit and a Micro SD Card 64 GB in Size and I do not know how it became Write Protected. So I Run CMD as ADMIN. I Type diskpart and then Hit Enter. Then I Type List Disk and a list of all my Drives comes up. Then I Type select disk 1 because this is my Micro SD Card. I Hit Enter and then Type attributes disk clear readonly I Hit Enter and it tells me it removed it succesfully. So I go into my Explorer screen and Right Click on this Drive and pick Format. And it tells me it is Write Protected. Can anybody help? Thanks for the Time.
