Was gonna buy an external HD but already had a spare 160gb IDE drive, so bought a USB2/Firewire enclosure instead (for IDE+SATA). Disk Utility only sees 31.5gb of it. It was originally NTFS, but I've formatted it as MS-DOS, and as MAC OS but it still only sees 31.5gb. I tried formatting it in my brother's PC to FAT32 (actually inside the PC case, not the enclosure). back in the mac it then appeared in Disk Utility as 31.5gb, but with 150gb available. That would be ok i suppose, but it doesn't work in the PC via USB/Firewire!! Can someone help?
