Cool 2TB USB Powered External Hard drive? Going on holiday soon, need help

Hi guys,
I need some help making a decision. I have been loading movies onto my laptop to make it so that when I am in a hotel I can watch my flicks. I am trying to find a passport drive that is 2tb, only usb2 connection, no power cord into the wall.

Here is one from HP that I found on Amazon. I really want western digital but can't seem to find a 2tb one with no power cord. Anyone use this passport from HP? If so, what do you think about it?

Also, if anyone could provide a link to a 2tb western that would be great. Thanks...

I don't think 2 TB USB powered external hard drives are available from any vendor. The drive linked above (HP SimpleSave USB 2.0) does have a power adaptor.

As you can see the maxium capacity is 1TB. It's the same for Seagate:

Re: 2TB USB Powered External Hard drive? Going on holiday soon, need help

The real problem is a simple electrical one. 3.5" drives require upwards of 2.7A at 12V to get started. USB power can only provide 1 to 1.5A at 5V. When multiplied up to 12V, the current load on the 5V bus would be over 6A which no USB system can take. Thus the external power supply.
If you look real hard, you might find a 1TB 2.5" drive (I think WD has one) you could put in your own case (Macally has a nice one) that would be powered by the USB 5V bus. 2.5" drives take less than 25% of the power required by their 3.5" brothers. For example, a Seagate Momentus 5400RPM drive only requires 1A on the 5V bus to start and run, and requires 5V only. A USB port can handle that easily. At the moment, you are limited to 1TB, but more later, no doubt.

Unfortunately, no. You still need an external PSU for 3.5" drives. Look into using a couple of 2.5" externals.

my son's mother has a 260gb external HD from WD that requires no power plug, you plug in the USB into the computer that's it. And I don't think it's a SSD HD because you can hear the drive spinning. It is very small about the size of a credit card and about a half an inch thick.

A 1TB is enough for movies you can fit a butt load of movies on 1tb = 1,000gb drive. So go with this solution.
