The drive needs to be connected to a plug in and through USB (1.0, 2.0, or 3.0)

I got it, cut and pasted 300 gigs worth of backups to it saw it complete a bit later on and took a nap for an hour. Came back and it was dead along with all the backups. Will try to break it open and see if there was just a failure in the power unit. It was ac tho..

You need to plug it in the wall with the electric cable. Then connects to the computer with the USB cable.

External power adapter to power it. I've had mine for about a year with no issues. It backs up every night too.

I believe it does require a special one. The difference is the computer USB cable has two plugs, one for the drive, and the other for the power. Perhaps one may be available through Cyberguys. http:/www.cyberguys.comLeo

To my knowledge, the larger ones (1TB +) seem to have external power. The smaller ones (less than 1TB) are just powered by USB. Those are the ones I have anyway.

Yes, the adapter is required. I have both 3.0 external hard drive and 2.0 flash drive connected to the hub and neither is connected when the adapter is removed. I didn't know that either from the info provided on the product page. The hub works well but I would have preferred a unit that didn't require the adapter to be used. Also, the adapter cord is not very long so you'll need to have your computer fairly close to an outlet. However, it really does work well.

You need to plug both USB ends. This way, your external HDD will draw more power than from a single USB 2.0 port.

the hard drive gets its power through the usb cable provided. no other cables are required.

The Prestige External hard drive is plugged an electrical outlet, an adapter which is rated at 12V and 1.5A. USB is specified to provide 5V only. It also has a power on/off switch which I find handy.

It needs the included AC adapter. This is a full-size 3.5" desktop drive inside. USB powered drives will typically be your smaller 2.5" "laptop" size drives.

No, it's intended as a desktop drive, meaning the external power supply is needed. But it's worth checking out LaCie's portable HDs. I have a 250GB Porsche-designed one that's been a workhorse for years.

Could someone who has one of these drives post the size of the power port on the back? I am interested in getting one of these with an external power adapter, and would like to be able to order simultaneously.

That's another thing I like about the Seagate, powered via USB port, no power adapter needed! One less cord!!

Each USB output port can easily handle a USB 3 current load ( which is Greater than USB2 Current load.If your External Drive strictly operates from the USB3( or USB2) data cable that also carries power, it should be able to deliver and operate it. No harm will be done try it. ( Note many External large hard drives also require a separate external DC power connection. Check and refer to your Hard drive manual for it's specification and connections. Good Luck.BobNaz

You have to have AC to power it. The smaller, "min" versions of the g-tech drives are able to be bus powered. Strangely, on the amazon pages per the technical details, in the "Special Features" section, it says "usb powered". However, upon looking at the g-tech web site and other resources, this likely just refers to it having usb ports...more of a marketing term than a technical term. I reviewed the technical manual, product guide and datasheet on the site for the product with no mention of being able to use the USB to power it. I will try with mine at home but I have had mine for a little over 6 months and had it AC powered the whole time. I would not expect a workhorse like that to be able to be bus powered.

You need a SATA to USB converter with power. Something like: Sabrent USB 2.0 TO SATA/IDE 2.5/3.5/-INCH Hard Drive Converter EC-AHDD

SATA3. It also has 2 usb plugs that go into your computer. One for the I/O and the other for power. I've noticed that the only time that the power one is really needed is if you're burning disks or if you're not using usb 3.0 for the I/O plug.

Hi, great question. You do not need an external power source such as an AC transformer that you plug into a 120 volt receptacle. After installing a SATA hard drive to your Sabrent enclosure, just connect the included cable from your Sabrent enclosure to any USB 2 or 3 port on your computer which will supply the necessary power to run your external hard drive and also send and receive data between your computer and external hard drive. Same as hooking up any of the USB 2 or USB 3 portable external hard drives on the market that uses your computer's USB 2 or 3 port to run and transfer data, and does not require an AC transformer to plug into the 120 volt power to run the external hard drives. Hope that helps answer your question.
