I have a 1G Powerbook G4 (superdrive) running os 10.2.8 I recently bought an external Firewire/USB 200G hard drive. When I connected it I got a message saying"you have inserted a disk containing no volumes that os x can read..." and was prompted to initialize it. When I try (using the erase tab in disk utility), it goes into "erasing" or "saving file directories" depending on whether I selected the Oxford HD bar or the Untitled Volume bar. In either case, the little blue barber pole goes on and on for hours but nothing seems to happen. I took it back to the shop that built it and they re-formatted as a FAT32 disk (they said that should solve it, but they knew nothing about macs) and it still didn't work, although after trying erase in disk utility it then came up as HFS+ volume, but says it is not mounted. I tried using "initialize" in os 9, but no luck there either. I also tried using usb connection instead of firewire but got same problem. Now when I connect it I get nothing at all until I disconnect it and then I get the "You have inserted a disk etc." dialog box. Starting to hope I didn't waste 350$, advice??
