Can anyone explain this?

I ran a full image backup successfully. I then immediately tried to check the image. The image did not verify, I was told it was corrupt. The verify failed in the first half of the checking somewhere. I then closed Acronis, did NOT re-boot and immediately opened Acronis TI8 again. I then did another check of the image. This time the image verified. Now, I ask, do I or do I not have a valid image? Am I supposed to have confidence in this procedure? The external 300GB hard drive is new within the last few days. The notebook is new within the last month. I have used the external disk to backup my desktop 240GB using Dantz Retrospective with no problems (it does a compare also). The notebook has on 80GB drive and I am using Acronis TI8. Is there a real need to exit Acronis before doing a Check Image?

 

There is no need to exit Acronis True Image after creating an image to perform image check.
Actually I have no ideas what happened.
Probable reasons are bad sectors on the hard drive and computer memory problems. But this looks very unlikely with a new computer and hard drive.

Anyway, I recommend you to run chkdsk /r command on the external hard drive.

Please contact support@acronis.com if the problem persists.

 

You can rule out memory as I have ECC.

 

Can not rule out memory, the notebook does not have ECC memory.

 

Run memtest86 on the system overnight to test the RAM.
