Just bout a Seagate Expansion Desktop drive 2TB. It's a USB 3.0 and it also works as a 2.0. I'm using a G5 PowerPC Quad Core. When I format the drive the drive disappears from the desk top, seams like it wont let me format it using extended journaled. When I format it using Ms-dos (fat) they formating works fine. But when I go to copy large files I get a error 0. Is this a problem with the drive? does anyone have this drive or would it be something with the OS 10.5.8?
Check if disc utility sees the drive (formatted as os extended). If it does, click the mount button. I find some times disc utility sees a drive I want to mount that finder does not. Works for un-mounting too.

I'm not sure about the extended journaled problem but FAT has file size limitations. I imagine you're transferring files larger than it can handle. I don't know what FAT format you are using but if you look at that and google "FATXX file size limitations" (XX is the FAT you're using) it should tell you.
