I bought 2 Pi 2 Model Bs on launch day. One is running fine but the other keeps corrupting the SD card after 1-4 reboots. At first I thought it was the SD card but I just flashed a brand new one (a different brand but both are good brands) and as soon as I rebooted after raspi-config it threw up the error. Most annoyingly I have a horrible feeling that the error is making the SD cards permanently damaged as I tried the first SD card in my reliable B+ and it suffered the same error despite the B+ running on its SD card for several months without any problems (same brand as the new one). Is the PI 2 faulty, is it a firmware issue?
Thanks in advance.
