SD Card Reader: The disk is write-protected

You cannot copy any files to the SD card using the SD card reader.

It says "Cannot copy xxxx file. The disk is write-protected. Remove the write-protection or use another disk" message.

1. You checked the lock at the side of the reader numerous times and confirmed it is not locked.

2. You have isolated the problem exists with the SD card reader and not the SD Card itself. When you plug in a separate SD card reader via USB, read and write works just fine.

3. You have downloaded the SD card reader program and installs the drivers needed. Rebooted and tried again, the problem still exists.

The following solution sounds stupid but it Works for me.

Place a clear tape over the lock.

This is to prevent it from switching to "Lock" position during insertion into the card reader.

Did you manage to write the file onto the SD card successfully?
