    I was wondering if anyone else has had a problem transferring a large file from an external HD via the USB port? I'm trying to copy a 10GB outlook pst file and the connection between the tablet and the HD keeps failing. small files are ok.
    anyone else having this problem?

    Surface Pro or RT? Are you sure you have enough room for a file that large on the internal drive?

    My Western Digital My Passport works flawlessly. It may be a limitation of the FAT format. Try NTFS.

    Is the external drive usb 2.0 or 3.0? In theory it shouldn't matter but I wonder it a usb 2.0 device could be an issue. When you installed the external drive did it install drivers? You may want to see if there are updates available.

    One issue I've noticed with the Pro is the default power saving settings like to turn things off once the tablet sleeps. You might want to ensure that your pro isn't sleeping before the file is finished sending.

    It worked with another external HD. This one is a 3.5 iomega. I think the issue with the 2.5 is somehow it's losing power during the transfer. I'm not sure if the problem was from the surface or the HD.

    Anything not over 500mA has worked for me.
