File formats

What is the hard drive formatted to?

 

Mac OS X can read FAT32 and NTFS formatted drives and it can also write FAT32 volume natively and with the help of NTFS-3G Mac OS X can also write to NTFS formatted HDDs.

I don't know if you can insert that 1TB HDD into your Power Mac, but you could either network Mac and PC or use an external USB or Firewire enclosure for the 1TB HDD. I advise to use a Firewire 400 or Firewire 800 enclosure though, as USB speeds on PPC Macs are very low compared to FW44 or FW800.

 

FAT32 is bad, it's not journaled.

 

FAT32 means that you'll be able to put the drive in the G5 and it'll read and write to it without any problems

 

Summary
"Journaling" is a feature that helps protect the file system against power outages or hardware component failures, reducing the need for repairs. Journaling was first introduced in Mac OS X Server 10.2.2, then to the non-server OS in Mac OS X 10.3 Panther. This document explains some of the benefits of using this feature and how it work
