I cannot get Disk Imager to read from an micro SD card. I get the following error:
Lock Error: An error occurred when attempting to lock the volume. Error 5: Access is denied.
There are no programs using the micro SD card and no windows open which I believe are using the img file.
I have tried rebooting the computer and the SD card adaptor is unlocked.
I have also tried several card readers and different cards both SD and micro SD.
