    Errors when copying from External Drive
    Hello all,

    I am trying to copy some files from an external hard drive to another drive. At first I have to wait for a while as it says "Preparing to copy..." and then it copies very slowly. After copying a few(different number every time I try) files, it gives me the following message:
    "Cannot copy file: Cannot read from the source file or disk."

    I have also received the following message a few times while trying to copy:
    "Cannot Copy [filename]: The request could not be performed because of an I/O device error."

    I am receiving these errors when I either copy to an internal Hard Drive or external Hard Drive.

    I ran a check disk, and it came back with the following message "Windows was unable to complete the disk check."

    I am very confused as I can access the files on the external drive, but it runs slowly as I try to open or navigate through the external drive. Also, I am confused, because it lets me copy some of the files, but then at some point gives me a error message.

    What can I do to copy files from the external hard drive?

    I hope you can help me as I have some very important files on the external drive, which I of course didn't backup. Also, please let me know if there are other options available to me such as recovery services or recovery programs if I cannot solve it on my own with your help.

    Thank you in advance!!

    Upon putting my external drive into a USB port on the back of the computer, I noticed it's A lot faster than the USB port in the front of the computer where I had it plugged in so far. It also copies correctly now with no error messages. I now see that BOTH of my front USB ports are not working correctly and the error messages were due to that.

    How can I fix the front USB ports so they work correctly?

    USB ports on the back support USB 2.0 drivers, whereas the ports on the front are using 1.0 drivers - This is way mfg configured the setup of your system - nothing you can do except use the ports in back as they support your ext drive 2.0 driver standard and ones in front do not
