I use 3TB External HD. Power won't turn on, but AC Adapter is not the problem. I'm told files are on disc, but Data Recovery needed. Will this help?

It should. However, if you're having a power issue with an external hard drive, and the adapter and cord are not the issue, your issue is going to be inside the hard drive. If it's under any kind of warranty I would suggest having it fixed that way. Otherwise, if you definitely have to do this yourself, you're going to have to open up the external hard drive in order to use this adapter's power adapter. I would suggest opening up your external hard drive first, if a warranty is not an option to fix this, to see if you can identify the problem before ordering this adapter.

It solely depends what you mean by External HDD. Is it a SATA or PATA drive? Then Yes. If it is one of those USB drives with Type 'B' power port then you cannot use this. (I believe!)

Did you turn it on? Is it fully plugged into the drive? I had an issue with an older ISA/EISA drive not getting fully plugged in. If you are using one of the 3.5" drives you need to check to verify that it is powering up. No power means it is not working. If you hear the drive power up (you can hear it spin up) and it is fully connected is it making any other sounds like clicking? If so the drive itself may be dead. There are several tricks to try if that is the case but without more details of the issue I can't help much more.

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.

Has anyone tried to connect an external HD to the USB port and saved their files?

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.

With only the info you provided, I believe the battery in the laptop dead, very dead. An external power source cannot fix that!

Couple months ago, I tried the WD Green 4TB HDD and it doesn't work. I don't know if it was the HD problem or the Plugable doesn't support it.

Derrick, it could be a damaged hard drive. I've used this device myself, and it works fine on good drives. If the drive is defective for any reason, it won't boot up.

Correct. I swapped it in for the old HD using only the PATA cable, no power.

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

try plugging it back to where it worked well. that's for checking if your hard drive is still good.

This did not work on my WD Blue 500GB drive. You need an external power source to power the drive. SATA connection worked fine. There just wasn't enough juice to power the hard drive even with both usb connectors plugged in.

If you are using the power adapter that is supplied with the USB hub the hub then is independently powered and the external drives are more than likely being "tricked" into thinking that there is still an active connection between the drives and the PC, therefore the drives will not turn off with the PC. If you unplug the adapter the external drives should then shut down also. Will the drives being on damage the drives? Not really, because there is no actual activity (reading/writing) taking place when the PC is turned off. Does it use a little electricity? Yes, but it would be minimal. Bottom line, if you are concerned about the drives being left on, unplug the power to the hub and they should shut down. If it means anything, I have a PC that I built with 5 Western Digital Black Series 4tb hard drives in RAID 0 and a 2tb external WD My Book attached that run 24 hours a day, 7 days a week and they are fine.

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.

I tried to plug in an external 320GB hard drive and it didn't work at all. The enclosure had its own power supply and I have plugged it into other USB Hubs before, but this one didn't even recognize it. don't know if it was defective or a limitation of the design, but I am returning it considering that I bought this Hub to swap multiple external hard drives and thumb drives. Hope this helps.

I am not quite sure since this was for my son and he used it. I said Used it because just last week when he turned it on he was asked to format it. We took it to a computer store to get it looked at and they said it was no data on the drive to recover. It had a bad sector and won't work. So we are in the process to see what we should do now. Soooo upset since we had just bought this November 26, 2011. Sorry that I could not help you.
