I recently got a big SD card for taking photos on a trip. While I was traveling and trying to mass transfer the files from the card to my computer (and I prefer to do move instead of copy for both time efficiency and metadata preservation). It then turned out that the card had write-protection. I struggled to get access to the internet but eventually did and found a method for remove the readonly attribute from the drive using a the diskpart command.
However, after taking more photos and going to mass move the files again, I have found that it is once again not letting me delete or move files, only copy hem, like last time. I repeated the command prompt sequence from before, but even though the command lines says it is has removed the attribute, things are staying the same. Everything else I have found either indicates this method, or changing the sharing protection or whatever in the properties, which isn’t showing up for me.
Check whether the card has a r/o microswitch
