My girlfriend got this problem a few months ago but didn't realise that the sd card stopped working. I got this problem about 2 weeks ago on my own xperia z. I haven't had the chance to test the sd card on a computer yet. A quick online search shows that a lot of people are experiencing this problem with sd cards suddenly failing when using the xperia z (variety of brands/capacity) but that sony has not yet officially addressed, acknowledged or responded to this issue. It would be good to know whether I can safely put a new sdcard and start using it without it suddenly dying and making me lose all my data. also, I can't seem to find where or who to contact to send my xperia z for warrany purposes? any pointers?
