Fix 2. Turn Off the Physical Switch (SD Card/USB)

We use removable storage devices a lot on a Windows computer, and some of you may encounter the issue of disk malfunction, which is mostly about "the disk is write-protected." When Windows starts to write-protect your disk, for example, a SanDisk 4GB USB flash drive, you can no longer use it anymore until you remove the write protection. But you can easily solve this problem if you have a physical switch.

Some USB flash drives and SD cards have physical switches on the side to protect data. If the USB drive or SD card switch is locked, the device could become write-protected on all PCs or devices. You can get out of this problem by turning off the switch.

Step 1. Find the physical switch on your USB or SD card.

Step 2. Remove the physical switch from ON to OFF and unlock the device.

  • Unlock SD card with the physical switch
