In brief, SD cards are indispensable to our lives and careers. But careless treatment can cause errors or data loss.
About one week ago, I tried moving files from the SD card onto the computer, but that was impossible. I thought there was something wrong with this SD card, so I attempted to format it via Disk Management and CWM. But I kept getting the same error: can’t format SD card. And I also placed the SD card in a USB card reader and SD card reader to format it through computers. It seems to me that this SD card is locked in a previous state and is write-protected. What’s worse, it won’t let me format it. So how do you fix an SD card that won’t format? Thanks.
