If I mount this in an external drive enclosure, do I need a separate power supply or will USB2 supply enough?

The drive power consumption is low, however; the external housing itself also would consume some power to create the connectivity. It would be best if you purchase an enclosure that uses a "Y" cable to connect the case to two(2) USB connector in your laptop.

It depends on the enclosure. Some enclosures are capable of powering the drive with just the USB.

No, it doesn't need a separate power supply, it can draw the power from USB port on a laptop. If you intent to connect it to an USB hub, make sure that the USB hub can provide sufficient power. Non/low powered USB hub will not work.

Well I've never mounted this type of drive into and external enclosure but I'm fairly certain (about 85%) that you'll need more power than what a USB 2.0 can supply. Then again, I could be wrong.

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.

Yea same thing with me I don't think it gets the recommended power from the usb ports...u should try the sabrent adapter...it comes with a dedicated power cable to plug into the wall and the adapters for 2.5 and 3.5 sata/ide hard drives.

This is a 36 Watt power supply, so yes, it should work with any of the "My Book Essential" external drives. But, note that this is not an OEM replacement part; it's an aftermarket item. Check the labeling on your drive-if it only needs a 18 Watt power supply, you can get an OEM power supply from the WD online store, if you care. If using an aftermarket power supply doesn't strike fear into your heart, this one should work.

Is the power adapter necessary for this drive or will it run off he computer battery if needed?

I don't think this hub is built to deliver that kind of power. All my external USB hard drives are separately plugged into the A/C. At minimum, your drive would probably have to be plugged into multiple USB ports.

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

yes , all you need is to put it in an external box. good thing it uses less power and has no moving parts so its stronger than conventional drives

all you need is a 12vDC 2amp power supply. i would take the drive with you to make sure the plug fits it

Yes, the SATA converter comes with a power supply so it won't work on just the USB interface.

It depends on how many drives you will use simultaneously. If it is only one or even two, you will have no problem powering them. However if you will use more than two drives, you should consider buying an externally powered USB hub.

It should only need bus power. I have used this drive as last in chain to a powered desktop drive (FW800) then into a MacBook Pro without using an external power supply on the G-Tech drive.

I have two that are self powered with no problems. In my opinion it should support 4 external hard drives because it plugs into a power source.

Your hard drive probably needs more power (current) than a single USB port can supply which is 5v @ 2A max

Depending on the drive.. Some smaller (2.5", 1.8", etc) drives enclosures require no additional power and if they are capable of using a single (or sometimes dual) USB ports for operation, you will have no trouble using them with this hub. However, larger drives (3.5") enclosures must be plugged in to external power source (they usually come with power adapters). For those you will not be able to operate them with this hub only, without external power source.

Sorry, I do not know, I could actually never fully install this because I don't have available power on the power harness, at least with the correct connection. I am disappointed that without power this doesn't even seem to work for usb1 and usb2 as it should. This was a disappointment.

The enclosure does not have any power management features, just an on-off power switch. If your operating system supports it, it can spin down the drive.
