When my hub is plugged in, my external drives remain on even after I shut down my PC. Is that normal? OK for the drives?

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.

For me I found external hard disks worked, but I would get short term disconnects. I replaced my hub with a Anker hub and haven't looked back:https://www.amazon.com/gp/product/B00GSLMTQ8/ref=oh_aui_search_detailpage?ie=UTF8&psc;=1

USB fans do shut off automatically upon shutdown. If my laptop is merely put to sleep, fans continue to operated even with lid closed.

It seems to power down when powered down. The light goes off and the drives stop spinning. I'm not sure about sleep mode, my computer is either off or being used. Hope that helps.

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.

No. If you are having problems you should try removing all devices from the hub. Then unplug the hub from the computer and shut down the computer. Turn back on and reconnect one device at a time. Mine has problems from time to time. Right now it is unplugged because I was having some issues with it.

You should be good to go. I don't keep it up all the time, but I have left it connected for weeks at a time. The hard drive is out in the open so it won't really overheat, and there is a power switch on it, so you can turn it off but leave it all setup when the drive is not in use.

Yes. You can set this in the Tools>Power Management option of the configuration. It has specific options to power down the drives after 5/10/15/20/25/30 minutes, or 1-5 hours.

The drive spins down according to your computers power settings (as all usbs will) but it never turns off.While spinning its not very noisy (you won't hear it in an office) but its not silent.I'm pretty sure its got wd green cavier as the drive.

Hopefully I understand your question, to make sure, I'll answer it in 2 parts. 1. Yes, the drive will "stay on" in the sense that your computer will be able to "see" the drive at any time it is plugged into the hub, the same as if you plug the drive directly into the computers USB port . 2. No, the drive won't necessarily keep spinning continuously. Hard drives (including USB hard drives) will go into a resting mode if they are not being called upon to "do" something by the computer. After a period of time, usb hard drives will go into an inactivity mode to save power and wear and tear on the drive (so from that standpoint, no, it won't stay on "constantly" draining power. However, as soon as the computer "asks" them to do something, they will power back up pretty much instantly. Hopefully that answers your question well enough. Cheers!

I have two external drives, and there doesn't seem to be a problem thus far. I've only had this hub for one month, however.

All hard disk drives have spinning platters, bearings, and other moving parts, all subject to mechanical wear. Your external drive will last longer if you un-plug it while not in use.Windows 7 will eventually shut down ALL HDD's attached to the computer that are not being used; both internal and external, however, this could take about 20 minutes or so. It is best to unplug your external HDD.Steve (Electrical Engineer)

Its here on my desk top right now, thus it is easy to verify your question. NO, the unit immediately went off line and disconnected. Upon application of the power it came back on line. I selected this unit for two reasons:USB 3.0 and the higher current capacity. I have in the past been frustrated with "low cost" hubs that won't charge a phone for example.Hope this helps.Michael

I have had no problems with this hub, it is a transparent little workhorse. I have three drives connected to the first three hubs nearest the on/off switches with no issues. I am not a good person to ask about the amps.

Are you using the proper power supply. I was cleaning rearranging my desktop, and inadvertently plugged the power supply from my modem into the laCie drive. It had enough power to turn the light on, but not enough to actually run the drive. I HAVE had a couple issues with my drive. The USB port now routinely disconnects for not apparent reason. Makes it difficult to copy large files.

I do in fact have a USB external 1gb hard drive connected to this hub along with 7 other ports taken by other devices. I have not had a problem with connection or speeds. I have noticed though that it takes like a second to load the drive, but my drive sleeps when not in use, so it does have to wake upon connection. I suggest getting it, I do not think you will be sorry.
