Default [Q] 64GB microsd sandisk corrupted by Sony Xperia Z?

Hi guys,

I have a 64GB sandisk class 10 microsd card that I used with Sony Xperia Z, it becomes unwritable now. I am unable to format it in windows or using sd formatter. the SD adaptor is in unlock position (i have used another microsd and it can be formatted.

does it mean that my card is faulty? Or anything I can try?
