Is this hard drive USB powered or powered by an external power supply?

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.

The hub has a 12 volt, 2 amp power supply. I assume the amp capacity is divided among the 4 ports. You'd need to find out what the current draw is of the external drive to be sure.

This is a 9volt DC power supply, rated at 1.5 amps. As long as know that the power requirements of the external hard drive are less than 1.5 amps, it should work. You have to match the plug and polarity to use it. This is very important. Incidentally cable is 5 foot long.

Mine did, external drives normally need an external power source. This was for an older WD MyDrive 500gb.

No external power supply on this unit. Just a regular 2 prong plug straight from the unit.

Yes, it includes a USB data cable & USB cable for power. Also, the drive I received was black, not white as pictured.

I ordered a portable external hard drive that uses a USB. Do not know what you a referring to.

NO! It is a powered hub. Having said that, I love these puppies. I've got 5 total in use and highly recommend them. (See my earlier review.) on USB 3 items, they'll draw power from their own power supplies and the computer itself, you DON'T ever want to take a chance of burning out the USB on your puter or the device (Like hard-drives) due to a low power situation, EVER!The plugable 7 port hub is lighted to let you know when the device is properly connected and powered, on each port.

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

I've never tried to use an external USB drive but I doubt it will power it. As for folders, it will display the

Power is provided internally via sata connection or you need an external enclosure if not installing internal drive.

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.

No. This device does not need external power. Direct plug and play ( like a thumb drive)

No, you do not need an external power supply for this drive. The 2.5" laptop drives are used extensively in passport type external USB only hard drives. Thought you must pay attention what enclosure you purchase. It has to have a power board inside that routes Sata3 to USB connection.

You are correct on your question. I don't use the power cable for my external hard drive

Steven it is USB powered but comes with a second USB cable to provide extra power if required. In my experience it seems to be needed. Regards John Docherty.

It's both USB powered AND has an external power supply. It has both. The AC power supply is provided for in situations where the device does not have sufficient capacity to power the Pawtec External 3.0 cd/DVD r/w, etc. device. This is more likely to happen with iPads, cell phones and other lower powered devices. Some netbooks might not have enough power, either. Hence, the product comes WITH an external power supply. Hope this helps.
