I've not had any success researching online or asking people, but I've managed to come across this site and thread. Since the thread's not dead, I assume it's safe to post in. I have a Walkman NW-A35. It's the Japanese model. Now, from what I understand, these devices are compatible with micro SD cards, and more specifically, 256GB Micro SD cards. Now, I've read through a number of posts in this thread that report that my particular SD card, the Samsung Evo 256GB, has been successfully used with this device. For whatever reason, my walkman will not detect that there are files on my micro SD card.
It has been formatted, both by my computer and by the device itself(I fumbled through the menus but eventually figured it out), and it's recognized when I plug the device into my PC. I can put files on the micro SD card just fine. I can play them as well, from the computer. The device, on the other hand, does not want to cooperate. It won't detect anything on my card. I can't even open the directories, being met with an error when I try to open the albums menu with the card mounted. I don't know why this is happening.
No, the card in question is not counterfeit. Every disk managing software I've used so far reads it as an actual 256GB card. Also, this isn't the only card it won't detect. I have a Samsung Evo 16GB card as well, and it won't cooperate with that card, either. Has anyone else had this experience with the Japanese Walkman NW-A35, and is there a solution? Formatting the card does nothing(it is exFAT). I can add files from the computer, but the device won't detect them no matter what I do. I can provide some pictures of the errors I get from the device, if that will help.
Yes, pictures of the errors may help.
Have you had success with the Walkman reading any MicroSD cards at all?
I’m afraid it sounds like a malfunction on the Walkman.
