    strange usb copying behavior


    yesterday i was copying a 6.8GB winrar file from usb to c drive,

    the initial transfer rate was 1Mb/second as shown by tera byte, it took 1 hour to copy 40% of the file.

    incidently my hand touched the usb drive while doing some other office work and the copy transfer rate shooted from 1Mb/second to 14Mb/second and the rest of the file took only 10 minutes to copy

    did the file copy correctly then? That seems very slow to start, I usually get from 60-200MBs with USB 2.0 devices. Starts fast and slows down before copy is completed.

    It was probably not inserted well. Loose ports usually default to USB 1 then when you properly inserted it, it got it's full speed.

    This is all just theory of course.

Ok so every now and then msert says it wants to send a file to Microsoft for analysis, the file is always something then generatedproxy cs. One of the suffixes was ACLM and cant remember the other but it was similar so it was ACLM_generatedproxy.cs or something like that. Any idea what it is.
