I ordered a 32GB SanDisk MicroSD card for my Desire HD from a cheap ebay seller. He seemed to have ok feedback and the picture showed the Micro SD card in the standard red SanDisk retail packaging. I paid around 20-22 bucks. I later got a message from ebay saying they had removed the listing due to the owners copyright infringement / fraud and sayed if I had paid they highly recommended I seek a refund. I am still waiting on my case with paypal dispute. Hopefully all will come good there. Just the other day I received the card from China or Hong Kong. It's obviously got different print to "real" SanDisk MicroSD cards I've bought and it came without the retail red packaging. The card didn't work at all in the SD card adapter when put into my laptop running Windows 7. My Cannon SD870 IS Digital Elph camera did recognise the card. I low level formatted the card on the camera and still the SD card adapter on the laptop didn't want to use the card. A USB adaptor worked enough to format the card. I did a full lengthy format. Copying 30GB or so of .mp3s to the card resulted in only most mp3s not playing.
