external power supply: does this hard drive have a connection for an external supply--like through an adapter?

No. It does not. The power supply is only via the USB connection and it draws its power from the PC/laptop it is connected to. With the price, I would expect a alternative direct power option.

No, the power adapter is for the IDE/laptop hard drives. I have recovered data from SATA drives without the adapter in place although I normally leave it connected for convenience sake.

This external HD comes with its own power plug, and it has only 2 inputs. One for the USB cable and the other for the Power cord. I am guessing it will only work with the power plug it came with.

Yes. This is an external hard drive enclosure, it will come with everything you need to use an external hard drive minus the hard drive itself. Which in this case the enclosure comes with a plastic stand to let the hard drive sit on its side on a desk instead of flat, a USB 3.0 cable (completely compatable with a USB 2.0 port, unless you have a new computer you probably have USB 2.0) and an eSATA cable and yes also an power supply cable.

If the drive is a 5400 rpm or solid state then no power adapter required. If its a 7200 rpm or faster, power adapter is required.

This unit is powered by the USB connector on your computer. No external power supply.

Are you talking about the external HD receiving power from the computer? If so, no, all of its power needs are supplied by the AC adaptor.

This item may help, but only if your external HD has a power supply or connection issue. This kit provides an alternative interface, but is useless to address actual problems with the drive hardware itself.

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.

No external power supply is needed. It is "plug & play". It gets power from the computer's ExpressCard/34 slot.

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.

External (non-ssd) drives require a lot of power. You will need to have the power adapter plugged into the card and use at least a 1am power supply. Also if you have other devices plugged into the other port, they consume power as well so you may not be able to turn the external HD unless it has it's own power supply.

There's not enough power (amps) through USB, it needs to be a self powered drive but yes it can hook up to the USB.Also must be formatted in FAT32.

External, AC adapter. It's a full sized, 3.5", hard drive with a full set of spinning platters inside. I'm not sure if it could even be used in a context where the device it's in would run off the power from a USB port....perhaps, but in this case, it's not that kind.

This hard drive comes with an external power supply module that plugs into a wall outlet. It is not a wall-wort but is a 4 x 2 x 1-inch block that comes with a removable cord that plugs into the wall and a second cord that will plug into a power connector on the hard drive unit, both cords are long enough to allow convenient connections. These are very good drives, I have four that are working very well. If your computer provides external eSATA connections, the drives that can accept this interface are MUCH faster than the USB 2.0 drives.

It appears to work powered by the AC adapter or the USB 3.0 cable alone. My USB 3.0 external hard drive works without the AC adapter. However in order to charge attached devices like my mobile phone, the AC adapter has to be plugged in.

If you use it for 2.5" drives then you don't need external power supply. You do need external power supply when you use it for 3.5" drives or DVD/Bluray drive.
