Is there an external on/off switch?

Unfortunately there is not. .A drawback ,but it works great and was easy to assemble.

no there isn't, you have to just unplug it or hook it up to a power strip with other items and make the power strip the master "on/off"

No, if you disconnect power you must manually turn it on. Cannot use it with an external timer.

No, there is no power switch. Because the drive has its own power, I believe the drive won't shutdown even when the system is off. But, it will spin down.

I do not think there is an on/off switch. You just have to remove the plastic from the battery compartment, so the battery can engage. Mine just comes on automatically when it gets dark and the battery is charged. I love mine!

No. There is no selection or switch. You just plug in and wait. It works fine for us.

There is no external power button. A shortcoming for sure, but what I did was set my computer to startup at a specific time each day in the schedule settings under power control in the system preferences.

There are no on/off buttons. As long as it plugged into a live USB 3.0 port it works.

There is no on/off switch. I plug it into an extension cord that has an on/off switch.

There is no on-off switch. The unit draws very little power from its wall-wart power supply which would remain powered-up even with the unit switched off. I recommend leaving it on or controlling it along with the other audio equipment. Powering it up while monitoring its output results in a loud "thump."

I do not believe there is an on off switch but you could unplug it when you are done if its in an easy reach.

Yes there is a switch on the bottom. It is really convenient because you won't lose connection with your device when you switch it on and off

There is no on and off switch--it comes on when you plug it in and unplug to shut it off. Not what I would prefer, but I haven't had any problems.

No on off switch. There is a sleep setting on the WD Drive Utilities software that comes with the drive. It is 30 minutes default sleep mode but can be set to other times.

Sorry, there is no such switch included. See my review posted around May 8, 2014. PAPA

Not sure if I understand the question but there is an on off switch. I have 7 external drives and they're all off unless I'm using them.

The enclosure does have an on/off switch. It worked great for what I needed. Opening and closing the enclosure is a little tricky if you are going to be swapping out drives. Adhesive steps under the top cover make it difficult to remove, but you don't have to use them.
