Hello. I bought the Seagate FreeAgent GoFlex 2T few months ago. It was formatted by Seagate in a way that it can be used under both Mac OS and Windows. As far as I recall, I was able to write to the drive under Mac OS. However, I used it to backup my Windows PC. I just tried to copy some files from my Mac to this drive. It mounted but for some reason, it is write protected. I tried it under Windows and I can read and write. Anybody knows how to remove the write protection? I tried disk utility but there seems to be no option for me to do that. sudo chmod -r 777 does not seem to help. Thanks.
