2) Can you see the files on the card from the phone? (via any file manager, not music players or galleries)
3) How much used/free space on the card showed in phone and computer? (on the phone Settings -> Storage, on computer, right click on the card in my computer -> properties)
Odds that both cards are fake are quiet slim, I'd assume.
There is no such thing as incompatible adapter with xD cards, simply because MicroSD to SD adapters contain no electronics inside, they are all mechanical and the same. However, card reader is another story, it could be incompatible with xD cards, in which case the result would be unpredictable, to the point that it could corrupt other files already on the card.
But that would not affect transferring files directly to the phone via USB.
I don't receive any error messages at all, the files seem to transfer fine but once I try to play some of the MP3s with power amp I am shown 'Failed to play file! "name of track".mp3'. It seems to be only the first 4gb of tracks I transfer are playable once on the device.
Going to start again...
-I have connected my note 2 via usb, using windows 7. Right clicked 'card' under 'GT-N7105' and selected format.
-I have copied 16.4gb (minus the odd playlist, jpeg or text file in some of the folders) of MP3 organised into folders by album and pasted onto 'card'...
-9.99Gb show on the card via the laptop before I disconnect
-Settings on phone show 62.50Gb total space, 45.94Gb available, so 16.56Gb should be used.
-Using the stock file browser most of the folders the MP3s are organised in are empty
- I select several random tracks to play in PowerAmp but get the 'cannot play file' message
- restart device
-try playing random tracks with poweramp but having the same issue, that most cannot be played
-storage settings now show 62.50gb total, 58.51gb available. so only 3.99gb of the mp3s are on the card now.
-connect via USB again and properties shows only 3.92gb on the card are used
Again no more than 4Gb can be used!!
