Have you tried more than one card? I had this problem with the first card I tried, in my case the phone was fine and the memory card had become corrupted somehow, so I had to buy a new card, my PC wouldn't even read it. If you have an adapter try removing the card and connecting it to your PC, if it reads fine then I'd guess it's a phone fault, if it doesn't, it's the card. If you've tried more than one and it doesn't read any of them it could be the phone, have you tried formatting or repairing the card? (OS6 - Options>Device>Storage Blackberry button>Format/Repair)
