I bought 1 of these cards from Amazon, to be used with a Fiio X1 DAP, but I cannot format the card to be able to use it.
The DAP simply says “Format failed”. When I connect the DAP to my computer, although the drive is eventually recognised, I cannot format it.
When I put the card into an adaptor and connect to my Windows 7 or 8 computers, the machine does not register that a card has been inserted, so I cannot even try using the apps I have found online (guiformat, SmartDisk_Fat32_tool, SDFormatterv4).
Is it possible that the SD slots on my computers are out of date (I’ve tried an 8gb SD card from my camera, and that loads fine)? If so, is there a product I can buy online that will allow me to connect this 128gb micro sd via usb 2.0, or is it possible that the card itself is corrupt?
I can’t imagine it’s a fake - it was from (and supplied by) Amazon.
Hope you can help!
