    Windows 7 Hanging when copying large files


    I'm currently getting what it seems like windows explorer ( or the status box when copying ) hangs when i try to copy files over 1gb ( i copy like 5 or more 350Mb files and its rock stable and fast - upto 50Mb/S over a 1 GIG ethernet link )

    I notice after its copied around 750 the status box freezes and it seems its not coping any more... its via 1 gb network link , both machines are fairly quick and i'm logged into the machine i am copying from using terminal services

    specs of 2 pcs -

    pc where files are copied from - Quad 2.4 , 4Gb Ram , 2.4Tb in Raid 5 , Win7 X 64

    pc where the files are copied to - dual core 2.26 , 4Gb Ram , 500Gb WD Hdd , Win7 X64

    I beleive its not hardware as i've copied like over 10 gigs of 350 mb files with out issue , only multiple single files > 1gb seem to have issues.

    Both PCS are running RTM. 16385

    As a suggestion, test what happens when you fully uninstall (disabling is not enough) your anti-virus utility and 3rd-party firewalls, if any.

    The most likely cause is interference from a kernel-mode filter driver.

    This might actually help with a problem I have making system images.

I am having some problems copying large files to my computer from an external hard drive. The copying process starts but then seems to freeze after a couple of minutes. Is this happening to anyone else and is there anything I can do?
