Hello Everyone!! I just bought a Kingston 8gb Micro SDHC Class 4 card for my Galaxy S, I placed it into my phone and it immediately recognized it. Everything fine here, problem was when I tried to copy some music to the card (with windows), first it was doing fine, then it suddenly stopped and showed me a message that it can't copy the file. Funny is that it copied some of the mp3s and folders, but after some, it didn't want to copy anything else always showing me that message. I tried formatting the card and tried connecting the card directly to the laptop with its adapter, but always I wanted to copy the folders and mp3s it always shows me the message that the files can't be copied. The phone recognizes the card and tells me I got 7.41gb of free space. I just can't copy files or folders there. Anyone knows what I'm doing wrong? Cheers!!
