Backup and Restore Error: The backup failed. New bad clusters were found on the source volume. These clusters were not backed up. (0x8078007D)
I can’t tell you what is the root cause of this problem but I can show you how to fix this problem in 10 easy steps. There are a set of screen shots on the next page if you need additional help in following these steps.
1) Close Backup and Restore. 2) Delete the Image Back folder (WindowsImageBackup) located in the destination drive. 3) Open Disk Management. (Start/Computer/Manage/Disk Management) 4) Note the size in GB for the partition Windows is installed on. 5) Right click on the Windows partition (typically C:) and select ‘Shrink Volume’. 6) In the ‘Enter the amount of space to shrink in MB’ box enter the value:1024(1.0GB) 7) Click the ‘Shrink’ button. When the process has completed you will see ‘Unallocated’ space equal to 1.00 GB 8) Right click on the Windows partition and select ‘Extend Volume…’. 9) Click on the ‘Next’ button in the ‘Extend Volume Wizard’ window. The ‘Maximum available space in MB’ value should be 1024 (see step #6). Click the ‘next’ button to reclaim the unallocated space you created in step #7. Click the ‘Finish’ button. 10) Disk Management should now report the size of the Windows partition equal to what you observed in step #4.
That’s it, you’re done. You can now run the ‘Backup and Restore’ feature.
Do you want to create a system repair disk?
Yes you do, for without this disk recovering your PC using the image backup file you created may not be possible.
If you have multiple computers with the first PC running Windows 7 32-Bit and the second Windows 7 64-bit then after creating your first image backup make and identify a system repair disk for each computer (the same applies for dual boot 32/64-Bit computers) as the size of the repair disks are not identical.
What caused this error to occur: I don’t have an answer. It could be a side-effect of a ‘Custom/Clean’ install which does make use of disk partitioning and formatting functions and it may even effect a few of users who upgraded from Vista to Windows 7.
I can tell you that when this problem first happened to me I ran a number of tests including ‘Check Disk’ on my Western Digital Raptor hard drive and none of these tests reported any problems with the hard drive.
