Does the 3 TB drive have a power switch on the case? I have another Seagate desktop drive that keeps running even after I shut down my iMac.

There is no power switch on the 3 TB drive. The disk will, however, spin down when the host machine is off.

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.

There is no power switch. The drive powers on when it is plugged into and being used by the computer. It powers off after a period of no use or when ejected.

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 Power no Data. Drive is dead to the computer without power. Also if you turn another switch on after boot up, computer doesn't see it. you must pick which hard drive you want before bootup.

Drive is powered by the computer (device) it is attached to. There is not external power or plug to attach one.

Yes one is for power the other power/data. I am running the drive on the data cable only. It did not run from the HUB without both plugged in, so I plugged the data cable direct to my laptop and it works just fine without the power cable.

The one I received didn't have that button. But I'd assume it was a one button backup that worked only with the software they send along with it. Either that or a drive switch button to switch between drives of you plug in more than one. Sorry I couldn't be more help.

The drive I use does not go to sleep of you have the power plugged in - sleep mode appears to be an OS effect.

Mine came with a power brick, for what it's worth. I believe that this hub corrupted my external usb 3.0 hdd, and pretty much killed it. Don't know this for a fact but I don't use it anymore.

So far, for me, when the computer sleeps, it disconnects the drive. When it wakes, it mounts it again. Sometimes, it just disconnects and reconnects for me while I am working. :(

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

Not to be too insulting, but have you made sure it's on? It does have a small "on" button, unlike some other drives that don't have an on/off switch.

It does power down but not to the extent of a wd green external drive, this one powers down after 30 minutes of non use, the wd green powers down after 5 minutes. You also gotta understand that these are external drives so their life mechanism is to power down because they use extra power directly from a power socket and because the drive gets very hot after continuous use inside the case, up to 50C with non-stop transfer in a hot environment like 27 C at room temperature. I transfered my avatar bluray rip that took 60GB the hole movie with all languages and subs and soundtracks, it took like 1 hour or so and the drive got to 60C, after the transfer the drive was so hot that it shutdown and it remained shutdown until it cooled down to a normal 28C. I still prefer for it to shutdown because it will make my drive last longer, but dont be fooled i've been a WD guy all my life, this drive is a monster, its fast, it makes no sound and still no bad sectors or whatever, would buy from them agaIn ASAP.

Yes, I'm running the 8tb version and it has the full 8tb, but for some reason I think the device used the first drive closes to the power button first for storage in this setup, but yes it works!

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

The drive came with a USB cable and a power adapter. I already had a WD 3TB HD for my mac. It has worked so well that I decided to get another one. Haven't had any problems with either.

I have a 2012 mac mini running OS 10.8.5 and the 2TB version of this and it works but it seems to go to sleep frequently telling me in the midst of working on something that I disconnected it improperly. That's been a frequent annoyance as it mens I have to start over or stop everything to wake it back up again and usually re-do what I was working on. I have not lost any data and it seems to work fine as a hard drive but I never have this problem with the Seagate HD.

Don't know, since I am using it as Time Machine on my Mac... I never turn the drive off.
