I am attempting to create a system image of my c:\ (Windows 7 Professional RTM) drive to a network drive. I keep getting the following message when the process completes: "New bad clusters were found on the source drive. These clusters were not backed up. (0x8078007D)" I tried running CHKDSK C: /R /F from an administrative command prompt. This necessitated restarting Windows and running CHKDSK prior to starting Windows. Following completion, I tried running the image creation again with the same message. Obviously, I do not want to try a restore since that could totally hose my system. I looked at the target drive and it does appear that a number of files and folders have been created, but whether these are any good or not, I am not in a position to say. Is this a documented bug, and is there a know fix?Windows 7 Professional RTM dual booting with Windows 7 RC (using RC to test Office 2010 in a test environment) 2 GB memory 160 HD Networked Gateway Laptop HP Officejet 6310 All-in One inkjet printer Verizon FIOS Internet Connection

Does it work properly if you back up the system image to a local hard drive? When does the issues occur, when backup starts or it runs in the middle way? Also please open Event Viewer, and find the log Applications and Services Logs\Windows\Backup\Operational. There may be some clues. I suggest that you temporary disable or uninstall the anti-virus, then run backup again and check the result.Arthur Xie - MSFT

It appears that the image back found a 512K bad cluster, but running CHKDSK /R dd not report this - see below. This occurred when I ran the backup to an external USB drive, or to the network drive. It occurs at the end of the backup. I will try running withmy anti-virus program disabled and see what happens. Ran with anti-virus disabled - same result. Here's what I found in the Event Viewer (both for the backup and the CHKDSK): Log Name: Application Source: Microsoft-Windows-Backup Date: 9/21/2009 9:39:03 PM Event ID: 525 Task Category: None Level: Warning Keywords: User: SYSTEM Computer: gateway_laptop Description: The backup operation that completed with warning(s) - Volume 'C:' has developed new bad clusters.

Ran a scheduled backup tonight to my external USB drive. This backs up a data partition and creates an image of my c:\ drive. The message box said that the job had completed and had a green progress bar (the attempts from the prior post had a red bar), but when I looked at the Event Viewer, it had the same messages - see below: I created this originally by creating a backup job - the images from above were from the Create a System Image option on the right pane.

The issue only occurs if you backup to a USB drive, but not occurs when you backup to local disk. Correct? I suspect that it is because the cluster size of the external hard drive is different with the local disks. You may open System Information by entering msinfo32 in Start Search box. Then expand Components/Storage/Disks, check the value of Bytes/Sector of each disk in the right pane.Arthur Xie - MSFT

Bytes/Sector for both drives are 512. Remember - this happens whether I back up to a local external USB drive or a networked HDD.Windows 7 Professional RTM dual booting with Windows 7 RC (using RC to test Office 2010 in a test environment) 2 GB memory 160 HD Networked Gateway Laptop HP Officejet 6310 All-in One inkjet printer Verizon FIOS Internet Connection

Do you have anything further to propose? The problem is continuing. I really do not want to test the completed, but reported backup image by attempting to restore it if there is another alternative. Two things: I know there is a way to run the backup from the command line. but I do not know the parameters. Could you tell me exactly how I should type in the command. Assume that I will be creating an image on my external USB drive which is designated as my g:\ drive, and that I will be creating it from my c:\ drive. If I do this, will a backup event log be created in the event viewer? My system is a dual booted system with a Ubuntu Linux partition. Could this be causing the problem (although I don't understand why this could be, since it is a totally separate partition and not an NTFS partition)?

I tried to restore an image and got a message to the effect that the system cannot be restored because the source volume is smaller than the target volume (I did not write down the exact message and since I did this from a rescue disk, I could not do a screen print). I assume that this is because of the 512k cluster that was not backed up. I created an image using Acronis True Image 2010 without receiving any such error message. I will try a restore with this and see it that succeeds.

Ok - this may explain the 512K discrepancy, but does not resolve the problem. Microsoft should look to find a way for users to make a usable image backup - otherwise the entire image backup utility is worthless for anyone running a dual boot configuration. Given what you are saying, I think it isfair to say that the problem is not a bad cluster - it is a cluster that Windows does not recognize. Apparently it can be done, as I was able to create and restore an image backup successfully using Acronis True Image 2010.

Hi, This error can occur if the last sector of a drive is corrupt. Unfortunately, chkdsk does not detect this failure and hence running chkdsk does not solve the problem. The workaround in this case is to extend or shrink the volume and then run chkdsk on it so that the failures are detected. Backup will then run successfully.Thanks,Sneha[MSFT]

I have just received the same error message at the conclusion of a system back up to my external USB drive. Thanks, DFrie_Burger

Hi,Sorry for not providing detailed steps. Please do the following:1. Start -> Computer -> Right click -> Manage -> Storage -> Disk Management2. Right click on the problematic volume.3. Select Extend volume or Shrink volume depending on whether you want to extend or shrink the volume.4. Select any number > 512 K. (For instance, enter 10 MB).5. Click Finish.6. Now, launch Explorer.7. Right click on the volume.8. Select Properties and navigate to Tools.9. Under Error-checking, select 'Check now'.10. Select both options and click start.11. If this is the volume running Windows, it will give you a popup saying it cannot check the disk while it is running. In this case, select 'Schedule disk check'. This check will run next time you reboot your machine.12. Reboot your machineNow, retry your backup. It should succeed now.Thanks,Sneha[MSFT]

I don't see any resolution to the problem. i.e. DFrie_Burger never got back on this issue to see if Sneha's solution worked. HOWEVER, I did just spend the last 5 hours doing what he/she [MSFT] said and it's BS. I got the same error message despite shrinking the volume, error checking/fixing, and running another disk image backup. If you are going to start a forum chain, at least have the decency of wrapping it up. The [MSFT] answer left dangling in the air did not fix the problem for me.
