    Constant DPCs When Trying to Copy/Sync to External HDD


    I am running an HP a6720f and trying to sync my photos to an external hard drive. I have tried to use both SyncBack and simply copying folders. In each instance, the process seems to start fine and initially copies well, but within a short time, it slows to a near halt. In all cases, my DPCs are jumping up from being insignificant (varying from 0-5%) to being around 35%, with hardware interrupts around 16%.

    I am not running any other programs when this happens. All I want to do is backup my pictures.

    The drive is a 500gb SimpleDrive. When I first boot the computer, I have no trouble accessing the drive or any files on the drive.

    Does anyone have any suggestions?

    There is a fix for this if your system is suitable :
    You encounter problems when you move data over USB from a Windows 7 or Windows Server 2008 R2-based computer that has an NVIDIA USB EHCI chipset and at least 4GB of RAM

    Thank you very much! There is a major improvement for copying files. I didn't think there was a problem with the drive (nor did my diagnostics). This confirms it. And more importantly, can backup my pictures.
