IOMega 1 TB External Hard Drive Keeps Turning Off During File Transfer
The external hard drive uses a USB and came with its own power adapter in which I have plugged in. Whenever a transfer is going on with a file larger than 1 GB, the transfer rate slowly decreases and the drive turns itself off and on. I've tried plugging it in a different outlet and a different port on the desktop but the same results take place. What is wrong with it?
Does this happen if the drive is connected to another computer? Try it if you haven't to find out whether it is drive or computer related. Have you tried a different USB cable? I strongly suggest you back up any data stored on this drive as it is possible the drive is failing. I take it that this is a recent problem and the drive performed as expected before this started happening.

I just purchased this external harddrive off of ebay yesterday and it came with its original packaging and all its contents. I tried connecting the USB to a laptop and transferring a large file and the transfer speed is significantly slower and also decreases over time. There's no data on the drive so there's nothing to lose.
I did a Google search and found many others have the same question but haven't found much in the way of a solution, yet. A couple of things I read include it could be powering down and to change this you need to check power management for the USB ports (Control Panel->expand the Universal Serial Bus tree->right click USB Root Hub->Properties->Power Management, uncheck Allow the computer to turn off this device to save power), another was a problem with the controller board inside the external case, and the last one was the drive could be loose inside the case.

What type of SATA ports do you have on your motherboard (SATA 1, 2 or 3)? If the drive is a SATA 2 drive and is connected to a SATA 1 port you will get slower transfer speeds. You could try defragmenting the drives and see if that helps. You could something like Defraggler (free download from http://www.piriform.com/defraggler) and see how much fragmentation is on each drive.
I believe the incorrect SATA plug might be the case here. The drive itself wouldn't defrag and would always stay at 0% and after running a crystaldisk check its health status came up as bad, so I just decided to send it back and purchase an actual internal harddrive instead. Thank you very much for all your help.
The ultimate solution is called "The Chinese Connection"! :-)
I'm using 4 laptops - 2 Dells, 1 Asus & 1 Lenovo. All are i7 varieties and 16 Gb ram. All of them are connected via USB3 ports to external HDD's by WD & Seagate. Capacity 3-4 Tb. All are externally powered.
ALL of them kept turning on & off on idle and on file transfer. I've searched everywhere and even tried Microsoft's silly hotfix ( http://hotfixv4.microsoft.com/Windows 7/Windows Server2008 R2 SP1/sp2/Fix373164/7600/free/435480_intl_x64_zip.exe).
2 weeks ago I got a private message from a friend who is a senior engineer in WD.
He suggested to buy from Aliexpress (or any other Chinese junk retailer) an external 7 port USB3 hub WITH AN EXTERNAL POWER SUPPLY CABLE and connect every external HDD to it.
Lo & behold! everything works perfectly now. On all laptops - all HDD's.
Cost is 9.5 -14 $ depends on the number of ports ( http://www.aliexpress.com/w/wholesale-usb-hub.html?site=glo&SearchText=usb+hub&CatId=708032&initiative_id=AS_20140929152554&shipCountry=il&pvId=493-4&isrefine=y)
