My Canon t2i

[Uptown Rando]

Hey, I have a Canon t2i and it only lets one of my SD cards Slide in the slot and catch. BUT it reads no card in Camera. SO I tryed other SDs and they for some reason Cant catch on in the slot... How can I solve this problem

If it's catching and not reading it, I'd definitely call the company. I've had a little trouble on ours with it not catching once in awhile, but it always reads it once it catches. Since it seems to be a mechanical problem combined with a technical problem, I'd send it in (or bring it to a shop) and have them look at it.
