Hello, I have a segate 7200.11 500gb disk, with SD15 firmware, and I recovered it from bricking two times in a few months with the gide posted in this forum. I read many post, but I don't know what to do. ¿Is safe to update to SD1A? ¿there are others problems with this firmware? Or Should I stay with SD15, so we know how to fix it? thanks.
