I've got a media player that doubles up as an external hard drive (2.5" hard drive inside it). This is the media player/enclosure - http://www.futeko.com/products/MP00024.php When connected to a PC, detected no problem. When connected to a Mac, not detected and doesn't show up in Disk Utility. I've done various searches and the majority of them either don't end up checking on a PC or do and get no joy due to the drive being dead. I know for a fact this drive is fine and I've also got an NTFS driver installed on one of the Macs, even thought it should still detect an NTFS drive even if it can't write to it, so thats a moot point. Any ideas?
