Summary: I'm very happy with this device which I use to do my Time Machine backups on my MacBook Pro. Just plug it in and walk away, when you come back, your computer is backed up and if you use a computer a lot and you aren't backing up regularly, you're making a mistake. If you do regular backups, it is likely that there will come a time that you'll be really glad you do them. This device makes it fast and easy.
Summary: I did quite a bit of research here on Amazon and other places before deciding on this particular model as my primary backup to my desktop iMac. I can honestly say, this little unit is amazing. Literally, I plugged it into the Mac using the enclosed firewire cable (which is short like others have said), a window opened on my Mac asking if I wanted to use the WD passport as my Time Machine backup drive. I said yes and with one click of the mouse, it took care of the rest.
Summary: I've ordered a number of external hard drives on Amazon; so far, the WD My Passport Studio 500 GB is the keeper. It's portable, holds the same amount of data as my PowerBook's hard drive, and couldn't be easier to deal with--it works quite literally out of the box. Do NOT bother formatting it with the included software--your Mac knows what do do with it.
Summary: Writing this review after more than two years of owning this drive. Have had absolutely no problems with it. I have a couple of Mac partitions and a windows partition on this and its been read and written to countless times. Solid drive, but a really late review !

Summary: I ordered this to augment/replace an older WD drive that was only 250MB, specifically because my Time Machine backups had eaten up all but 3.5MG of the available space. I'm using the firewire connection and all appears to be just fine. I'm afraid I don't know all the technical oohs and aahs, but this drive suits my purposes just fine. No complaints at all!
