Windows 7 Premium reports failure every time I try to backup onto an external drive. It’s a MyBook with 1 Tb and lots of free space.

    Hi

    Is HD password protected?

    Follow the instructions to perform the chkdsk, which might help you in resolving the issue.

    1.Click Start, type cmd in the Start Search box, right-click cmd in the Programs list, and then click Run as administrator. If you are prompted for an administrator password or confirmation, type your password, or click Continue.
    2.At the command prompt, type Chkdsk /f, and then press ENTER.
    3.Press Y when you are prompted to check the disk next time that the system restarts.
    4.Close all applications, and then restart the computer.

    Note During the restart process, Windows checks the disk for errors and then starts.
    5. After the computer has restarted, try running backup again.

    Method 2:

    1. Click the Start Button and click on Computer.

    2. Right-click on the hard drive you would like to check and choose Properties.

    3. Switch to the Tool tab and click on the "Check Now" button. Click Continue if necessary.

    4. Select both the "Automatically fix file system errors" and "Scan for and attempt recovery of bad sectors" options.

    Note: If we are trying to check the system drive, we may need to restart the computer to complete the check process.

    5. Click Start.

    Note: It is recommended to repeat the steps above to check the disk twice so that most of the error can be found and fixed.

    or
    This issue occurs because the VSS [Volume Shadow Copy Service] system files are not registered.

    To resolve this issue, follow these steps:

    1. Click Start, in the search bar, type cmd. Right click on the command prompt to open it as administrator.

    2. Type the following commands at a command prompt. Press ENTER after you type each command.

    o cd /d %windir%system32

    o Net stop vss

    o Net stop swprv

    o regsvr32 ole32.dll

    o regsvr32 oleaut32.dll

    o regsvr32 vss_ps.dll

    o vssvc /register

    o regsvr32 /i swprv.dll

    o regsvr32 /i eventcls.dll

    o regsvr32 es.dll

    o regsvr32 stdprov.dll

    o regsvr32 vssui.dll

    o regsvr32 msxml.dll

    o regsvr32 msxml3.dll

    o regsvr32 msxml4.dll

    Note The last command may not run successfully.

    See if you can save your Windows 7 backup image to a primary formatted partition on your HD, then copy it to your external drive.

    That way you have a recovery partition ready to reimage your HD by booting from the Windows 7 DVD Repair console or Repair CD, and an external backup in case of HD failure.

    or

    convert the destination disk (disk you're backing up TO) from Basic to Dynamic.

    1. Click the Windows button
    2. Right click on Computer and select Manage
    3. Click on Disk Management in the left pane
    4. Select and then right click on the Disk you want to convert
    5. Select "Convert to Dynamic Disk"
    6. Use defaults through wizard

    Hansi,

    what exactly is the error message Windows 7 gives you?
    Were you ever able to backup from Windows 7 onto this external MyBook drive?
    How did you previously save files on it, i.e. from where or what operating system?
    What is the file system on the external drive, e.g. NTFS or FAT32 or other?

    Please try to answer these questions so that we can help you solve this issue. Thank you!
