I currently use a SanDisk Ultra 4GB SD Card (class 4 - up to 15 MB/s) for my application and it works fine. I recently tried to use a SanDisk Ultra 8 GB SD Card (class 6 - up to 20 MB/s) and the application now fails every time with the following error. I tried another 8 GB class SD card by Wintec and it worked fine. Would it be due to the high speed rating of the SanDisk Ultra 8 GB SD card? This is a production application so I was just trying to go with the highest possible quality (and quickest) SD card without breaking the bank.
