Hello, So I am incountering and issue where any sd card I insert in my mac does not let me copy files to it or re format it. So, for starters it will never remember that I have it set as list view table in the finder, and always reverts to the collection view, wich I really dislike. Also, I cannot put files on any of my cards anymore, wich are a 4 gb card, 32 gb card, a 2 gb card, and a 128 gb card which I am very prowd of. When I try to erase with disk utility or perform firstaid, the disk will eject itself and will not work with disk utility. Also what is weird is I can use the cards properly with my other devices aka bookport plus and braillenote. Any help is appreciated.
