offf. I havent had to use one of those for anything for a long while. outside of the write protection switch. no idea other then firmware of the reader will not read that card for some reason. I have seen issues with size as fairly common. where they will not read cards above some certain size properly.
actually all my others were micro with different adapters, I would have to dig them out somewhere since moving. Thats why I tried this one out of desperation.
I'd start with trying that card in another reader or another card in that reader.
