    ERROR 0x8007045D: While performing backup to External


    Good day

    Apologies if this is in the wrong forum.

    Yesterday while trying to backup a 50GB folder, I received the following error:

    ERROR (0x8007045D): This request could not be performed because of an I/O device error.

    I am trying to backup from my C: drive to any USB3 External. I have tried different USB ports and devices (Flash and 3TB External). I have been on multiple websites and tried the below - Still no luck

    Safe Mode copy
    Windows 8 check disk

    I have no idea what else to do. I would appreciate any assistance.

    Thanks in advance

    Just tried to break it up into smaller copy segments and still no luck. It is the same file every time.

    Yes same file, but if I skip that file, then there are more files with the same type that cause the error. Seems like we are getting somewhere. I can CUT (move) the file, but not Copy it. I have run a repair on the game files as well as a check disk on the drive. The files are not showing corrupted. Any suggestions?

    So the folder I'm trying to copy is my Battlefield 4 install directory. In the Data folder there are files that end with .sb - These files are movable (CUT), but I cannot copy them
