Hello All, I have searched all over and have tried many fixes for this issue, but have not found one that works. Every SD Card or Micro SD card I own works in every other device, except when I plug them into Win7. It tells me that the card needs formatting, I try to, then it tells me Windows can't do it! I have tried them in each of the 3 Win7 systems I own with the same result! Any help tackling this problem will be greatly appreciated.
