128GB SD card problem

[Timax777]

Bought a 128GB SD for the phone..it mounted and i was able to transfer video, photos and music to it to release space on internal memory, looked at it today and it has stopped being recognised and all of the data has returned to internal memory. I cannot do anything with the card as it is not being recognised by the phone. I then reinserted my old 16gb sd and that won't allow me to transfer anything either...**bleep**?

What file explorer did you use to transfer?

The same here, I tried to format the card using diferent ways and the same keeps happening. 

I use the Sony Bridge for Mac to transfer. But when I transfer it manually using file explorer the same keeps happening.
