Will any external usb 2.0 portable HD work? Or does it need to be a certain file type? Western Digital has portal HD's specifically for Macs. What's the difference with their standard ones?
Any USB 2.0 or Firewire 400/800 HDD will do. The HDDs advertised as being made for Mac OS X are just pre-formatted with HFS+, the file system Mac OS X uses.
You can do that yourself via Applications / Utilities / Disk Utility.
Also on first connecting an external HDD, you will get prompted with the following message, if you choose YES/USE, the HDD will be formatted correctly.

1. Yes.
2. The only difference between a "hard drive for Mac" and a generic hard drive is that the "hard drive for Mac" will cost more.
3. Avoid hard drives with fancy software installed of them. It is either useless and you pay for it, or it really gets in your way and you still pay for it.
Basically, take any portable hard drive, plug it in your Mac, start "Disk Utility" (in the Utilities folder in the Applications folder), in Disk Utility select the new hard drive, click on "Partition", and choose Format = "Mac OS Extended (Journaled)", that is essentially what makes it a hard drive "specificially for Macs". Ten seconds work vs. lots of dollars and it gets rid of any software that you _really_ don't want on your backup drive.
Then you set up Time Machine, that's it. Obviously the first backup always takes quite a while.
Thanks guys. I got a Lacie by S+ark 500gb. I must have paid additional for the design and software that came on it! But I gotta say, I am loving the design cause I can strap the built in USB cable into it.
