Hi, I have recently purchased Western Digital USB hard drive to use as a back up disk in case one of the mac goes down. I have a Intel MacBook and a G5 PPC. The MacBook will back up from this disc fine but the G5 won't. After reading up on the internet I have found out that this is a well known problem between the Western Digital Drives and the G5. Can anyone recommend an external usb drive that they know to work with the G5 ? one that it can be used as a start up disc. Thanks in advance.
