My SD card reader (built-in slot on my Macbook Pro) is unable to write or delete files. How can I make it writable? Just to confirm, this is not a problem with the card itself, as it works with other readers. I cannot format the drive. Opening it in Disk Utility gives me this:
So you can see where the problem is. I sometimes use the SD card to transfer files, and I would rather not use a separate piece of hardware. Is it physically incapable of writing files?
Whoa, somehow I fixed it by leaving the physical lock on the side of the SD card between the usual positions. I'm just saying I don't need help now. For some reason I'm not allowed to edit my post or delete this thread.
