Just rebooted my her0 cuz wifi was broken and all of the sudden my SD is kaputt ... can see and read mounted contents on win7 but cannot copy or repair. Any ideas?
Since rooting I can no longer mount my SD card while it's in the Hero, unless I go into the recovery mode and Turn USB Mass Storage On. Then it mounts like normal. Haven't tried formatting it yet, need to copy stuff off then try.
A bit more digging and it turns out that this is a known issue impacting multiple devices.
