Ok, my brother bought a motorola a1200 and just today bought a 1gb microsd card. The card couldn't be read on my computer. The drive would come up on the my computer screen but when I click it it says there is no disk. I have tried different microsd adapters and different card readers. I tried to format it, but it still says there is no disk in the drive. So, I have put the card in my phone (LG CU500) and Transfered songs to the card via bluetooth and they can play on my phone but not on my brothers. Is the card bad or am I doing something wrong?
