Hello, I'm having issues with transferring large amounts of data from my WD Elements 1.5 TB external hard drive to my internal NTFS formatted SATA hard drive. I keep getting the following error message: 0x80070037. A quick google search about the error generated a thread that discussed that "power from the motherboard may not be ample enough to keep the external drive powered", thus the failure in the transfer of the data. But this external drive has it's own AC power supply, so I'm confused. Essentially the external hard drive keeps dying no matter which USB port (front & back ports) I plug it into. It works fine in three other household PC's. I'm not sure what to do, but thought I'd start here and see if any of you Microsoft experts could comment on this issue. What info do you need to help me diagnose this issue? Any reply is appreciated. Thanks Note: Another person experienced this problem after installing some Windows updates. Is it possible that the updates are causing this issue? I just installed a large number of updates with this PC.

Hi, 0x80070037:The specified network resource or device is no longer available. A power supply issue may be a cause. But also many issue may cause this problem. Since it works fine in other computer, I suggest that you may check the USB port. Please try to plug this device into the USB port which in the back panel. Also please collect the hardware installation log file in the path of %WINDIR%\Inf\Setupapi*.log, upload the file via SkyDrive and post a link here. Then we can find some information from this log. http://explore.live.com/windows-live-skydrive?wa=wsignin1.0 Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

I don't think it's likely that it's caused by an update. First thing I would want to see is your usb drivers and versions. At a command prompt, type this: dir C:\windows\system32\drivers\usb* And show me the output :) Power failure is potentially the problem, but your issue is essentially that your device is disappearing during the transfer for some reason. Something that might help is if you open device manager (devmgmt.msc) and change the view to by connection (View -> Devices by Connection). Look around until you find your external hard drive, and just watch this tree during the transfer. When it fails, whatever the highest thing up the tree that goes away is, is probably the culprit. Also, occasionally the motherboard is bad and has issues with big transfers. I know that on my desktop at home, if I use the front ports for a big transfer, it'll fail. You might just be unlucky and a lot of them have the same issue. You might want to literally try every USB port and see if some work - and remember which they are. USB ports are hooked up in pairs, so usually you'll notice that there are always two next two each other. There is usually no difference between the two ports in the pair. So when you're trying them all, you can just test one of the two in a pair (might save you some time :) )
