Any Way To Recover a Corrupted Image?
Hello all,
Have a client's Vista system that we had to do some work on the service packs. e know how problematic that often is, so we removed the hard drive, connected it to our Acronis machine, and pulled an image. Imaging completed, and the image was mountable and accessible.
Reinstalled client's hard drive, removed Vista SP2, and unsurprisingly, it crashed the system. Connected hard drive to our transfer machine, restored the image, it completed successfully. Client's system is once again bootable.
Attempting to modify the service pack a different way crashed the system again (I hate Vista). We then restored the image to the drive again. This time it gets to 66% and says the image file is corrupt. Rebooting doesn't help, running chkdsk on our image drive doesn't help.
Any ideas? Losing the client's data would be a problem...

Okay, the image is mountable, and the data itself looks accessible that way.
Any way to get the image to the point where it can be restored, so we can avoid a O/S reinstall, along with all the programs, printers, etc?
I know this image was functional yesterday, we restored from it then. But now its not.

Run a validation check on the backup image to check if it is still ok.
And then try restoring it to a partition which has been already formatted.

Yeah, I had already been running a Validation on the Image, and it fails.
Does that pretty much rule out the possibility of a successful restore?

I dont know how to repair a corrupted backup image.
If you are able to copy the entire contents from the mounted partition to the boot partition it might be able to start up the os.

There is no way to repair an image. If the validation fails in Windows, does it fail on the recovery CD?
A failed validation is not always because of a corruption in the image. A validation can fail because of hardware issues (memory, disk or network I/O).
Conversely, if the validation succeeds, there is a much higher level of confidence that the image will restore successfully.
If the image mounts successfully, you have also a very high level of confidence that the image will restore successfully.
You could try to restore on a spare disk if you have doubts. You could also take a new backup from the current system before trying the restore.
