I have owned the Xperia Z since it launched and I have been using a san disk 64gb memory card since the release too. Up until last Sunday (March 23rd, 2014) I had been using the phone and memory card perfectly fine with no problems.
On Sunday I was in the middle of recording a video and then the phone popped up with a message saying "Memory Error - Memory write protected. Could not edit files". This has never happened before and since Sunday I have been trying everything to resolve this issue but nothing has worked.
I can use the camera with the internal memory but not the memory card. Google Play no longer recognises the memory card. My Album app can still see the card and allows me into the "My DS card" album. File commander can see the memory card and everything on it.
It seems that my memory card is srill working and beeing recognised, but I am no longer able to write to it.
Please help.
