Coprrupted files after copy RRS feed

  • Question

  • When I copy a file (for example 220 mb) from my local drive to my external USB drive, the files get corrupted/damaged. When I compare the files, using FC /b, it founds several binary differences. The file sizes or modified date stays the same.

    After copy from local to external USB drive
    C:\Users\Jurriaan>fc /b k:\sqlexpr_adv.exe e:\sqlexpr_adv.exe
    Files : K:\SQLEXPR_ADV.EXE en E:\SQLEXPR_ADV.EXE comparing
    02E156FF: F4 F0
    03094FA2: 20 28
    03094FB2: 81 89
    076CDE65: ED EF
    076CDEDE: DC DD

    Output when I copy the same fle from one partition to another partition (same physical HD)
    C:\Users\Jurriaan>fc /b c:\sqlexpr_adv.exe k:\sqlexpr_adv.exe
    Files C:\SQLEXPR_ADV.EXE en K:\SQLEXPR_ADV.EXE comparing
    FC: no differences found

    Hi Jursel, have you installed latest updates on the computer including Service Pack 1? I recommend you first install them via Control Panel – Windows Update.


    If you have already installed them, please go to Safe Mode and check if this still occurs:


    1. Restart the computer.

    2. Keep pressing the F8 key until the Windows Startup menu appears.

    3. Choose Safe Mode by using the up and down arrows on your keyboard, and press Enter.

    4. Start the computer in Safe Mode.


    (Note: In Safe Mode, your system display and Desktop will look and perform differently than in Normal Mode. This is only temporary. To return the system back to Normal Mode, we can simply restart the computer. )


    Hope this helps!
