Hello All, I'm really close to jumping on the G5 Quad bandwagon (transition from a PC). However, I need some advice on one thing in particular. Since being a PC guy forever, I have experienced too often the need to trash and reload the Windows operating system. I have never taken the time to investigate if or how the option to add a second physical hard drive would work, and keep the operating system on one drive, and my programs and data on another physical drive, with the idea that if the OS ever needed to be reloaded, that the programs and data would remain intact and not be affected. I want to know how or if this would work on the G5. I have contacted Apple, and they indicate that they probably can't make such a thing happen from the factory, but that the Apple support folks could walk me through how to do it. They also suggested that a cost effective solution would be to keep a copy of the OS on an external hard drive and be able to boot the computer off that drive in the event that the internal hard drive OS became corrupted. In order for this to address my issue, however, I gather that I would need to have an EXACT copy of EVERYTHING, including programs and data on the external drive, to prevent my original issue...having to reload and restore all the programs and data in the event of having to reload the OS. Does anyone have any experience in trying to do what I'm asking about? The only 'factory' option regarding 2 INTERNAL disks is a $800+ dual 500 GB option, which is way more storage than I need. Does it make sense to be able to have a separate drive with the OS on it to make a 'reload' easier in the event of such a need? Is an external drive reasonable? Am I being too worried? Based on my PC experience, and the nightmare that is caused by having to redo Windows, I'm inclined to do whatever it take to avoid that pain! Thanks for any advice in advance.
