Recently purchased the pi 2, previously had the 512 with no issues but wanted the upgrade. This new one is causing major issues corrupting the micro sd on every reboot. Each time it's turned off or restarted it runs a check disc error and fails to fix so I run fsck -fy /dev/mmblk0p2 entered in the command prompt with a reboot. This sometimes resolves then other doesn't. Leaving with with no option but to reformat the card and start again. Any help would be amazing !!
