I just bought a new walkman nw a-35. I say new, it was open box at crutchfields but unplayed.
I bought a new sandisk 128gb extreme plus sd card so i would have lots of space. The walkman never recognized the card was inserted. Sony told me i needed to format if. I cant format it because the player didnt recognize it.
my computer and my tablet recognized it.
so i took and old 32gb sd card and formatted it on my computer to 32fat. The walkman still didnt know it was there. Funny thing is that when i connected it to my computer, the computer knew it was there.
i was tempted to send it back, finally i found an old 4gb card laying around and stuck it in and it worked. I put music on it and everything.
