I ordered a 500 GB Western Digital My Book Pro edition today. I love the silver look to match my Mac stuff, and the Firewire 800, for the future (my macs can't use it right now). Is this a good drive, for use with my iMac? Any idea the best way to partition? I wonder what would be the best for when Time Machine comes out? I put my Mac to sleep a lot, so I hope that won't cause any trouble, with an external drive connected. Thanks.
