Ok. Consider my problem solved. I had a faulty power strip that the hard drive was plugged into which caused the intermittent power issues thus generating the error message and transfer failures. Thanks for the quick replies.

I just stumbled across this thread after having issues with transferring large amounts of data from my Western Digital Elements 1.5 TB external hard drive to my internal NTFS formatted SATA hard drive. I keep getting the following error message: 0x80070037. A 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. The power seems to be intermittent, as the device dies then comes back to life after a few minutes. It dies no matter which USB port (front & back ports) I plug into. It works fine in two other household PC's. This external drive has it's own AC power supply, so I'm confused. Does USB power have anything to do with this problem if the external drive has it's own power supply? I read earlier in this thread that replacing the USB cord can help. What type of USB cord should I buy? Additional info (if it matters): I'm running 64 bit Windows 7 with all of the current Windows updates. Asus Motherboard: P6T SE Thanks!
