SD card problem

So a little bit ago I took the my 32gig SD card out of my phone put it in my computer to transfer a couple movies over faster to my external harddrive and once it was complete I put it back in my phone like normal and it said it was corrupted. I put it back in my computer and transfered all my files on my desktop and put it back in my phone let it reformat it and it shut off. And wouldn't boot back up unless I pulled the card out. I tryed it again with a good 16gig and same deal. Any idea why this would be happening. I can't even format them on my computer. Is it my phone doing this. Anyone else experience this problem
