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?

Thanks for your help :)

I would try two things.

Repair permissions.

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.

open a terminal and run the following:

$ sudo tail -f /var/log/kernel.log

Try to partition the drive again as HFS/journaled. I'm guessing something useful will pop out on the terminal.
When done, hit control-C in the terminal and post the messages.
