System image - back up failed

Question

When I have tried to create a System Image I keep getting an error, "The backup failed. New bad clusters were found on the source volume. These clusters were not backed up. (0x8078007D)"

I'm running a Windows 8.1 Pro Upgrade over 8.0

Can you please help me understand;

• what this means
• how I fix it

Answer 1

Hi,

Do the following.

1. Hit Windows key + X and click "Command Prompt (Admin)".
2. Type: chkdsk /f and hit Enter.

You'll get a message that a diags check can't run because the volume is in use and whether you want to run a diags check on the next reboot.

Click Yes and then either reboot immediately, or finish what you're doing and then reboot.

A diags check will only take about ten minutes. Chkdsk can fix bad clusters using the /f switch.

If that fails to resolve the problem, open the same command prompt again and then type the following command and hit Enter:

chkdsk /f /r

With the /r switch included, the tool will scan the entire disk for bad sectors and mark them as such so that they can't be used. This particular diags check can take several hours and can't be interrupted once started.

You can also copy each command and then right click in the command prompt and click "Paste" instead of typing a command.
