Hello!
I recently bought a Western Digital Passport External Harddrive. It's usb powered.
I tried plugging it into my Dell Inspiron 600m's usb ports- BOTH of them, around five times. The HD would make this powering up noise, stop, shut off, then do it again over, and over, failing to really start up. And also a clicking noise when trying to start up again.
When I go to "My Computer" sometimes the hard drive would show, other times it'd just make the whole "my computer" window freeze, then it'd close itself, my desktop would go blank except my wallpaper, and then everything would come back without the "my computer."
I plugged it into another Dell desktop and an IBM laptop and it works PERFECTLY fine on those two.
So I'm guessing it's my laptop then?
Anyone have any suggestions on how to fix this?
Yes I tried the first usb port once, then then the other usb port when the first one didn't work. And then 3 more times.
Would a usb hub be a good option as well? Those things with 4+ jacks for usb cables?

at the same time with 2 USB plugs or only one, once in the 1st and there after in the 2nd?
it depends on the drive enclosure you use. there are some they need an extra USB plug for power only and a 2nd USB port for data and power. (i have 2 external notebook hard drives. the one works fine with one USB plug but the other does the same as you have described. i can't get it to work without an extra plug for power, either a 2nd USB plug or a PS/2 plug).
to solve your problem: get a Y-USB cable. this is a cable with a plug for the enclosure on one side and 2 USB plugs on the other side for plugging into the computer.
i suspect that the power provided on one USB port of the Dell 600m is too less to power an external notebook hard drive.

Sounds like there isn't enough power from the USB port and that there needs to be more power going to it than a single USB cable.
Every USB port is limited to 0.5A before going into current overload. The USB monitor will disable any USB port that exceeds this current limitation to protect the port from being fried.
Typical drives will consume 1 ~ 2 amps on spin-up and then go down to about 500mA once they are spinning.
Unless you dropped it hard or hear strange clicking sounds, I suspect that if you use the additional power port with the exact voltage and at least the minimum current requirements that you should be fine.
Try this first and DO NOT LEAVE IT IN THE FREEZER OVERNIGHT !!! THAT IS A SURE WAY TO KILL IT.
