CRC Validation Errors in Ghost 15 and How I Solved It

I've been runing Ghost 15 since the very day it was released and it's been backing up my computer daily without a glitch ever since. Until about 2 weeks ago that is.

A few days ago I noticed that my backups had been failing almost every day with the following error:

Error EC8F17B7: Cannot create recovery points for job: Drive Backup of System Reserved (*:\), (C:\).
 Error ED800012: The internal structure of the recovery point file (CRC Validation) is invalid, damaged or unsupported. (UMI:V-281-3215-6071)

Details:
Source: Norton Ghost

I have Ghost configured to perform a verification of my backups. I'm not sure if this CRC Validation only happens when verifications are turned on not, but I thought it worth mentioning that I have this option enabled.

I went back in my logs and noticed that the backups were failing every day for about a week with the exception of a single day where it succeeded and that one was just a small incremental backup. I tried to perform a number of manual backups and these too failed.

It finally dawned on me that about the time that the errors started I had updated my NIC driver to a new version and the backups that I was performing were backups to a network location. As a test, I first backed up to another local hard drive and that worked. Now I was starting to wonder if the new NIC driver might be the problem. Fortunately, I had kept my previous NIC driver (I always keep old drivers until I really know for sure a new one is working!). I reinstalled the previous driver and have run at least 6 backups since then - every single one has been perfectly successfull.

I'm sharing this information in the hopes that it may help others. I especially noticed that others with the same error I was seeing didn't seem to have any real resolutions. Here are the key points:

1) It might be a good idea to turn on validation, at least initially until you know your backups are reliable. After making changes to your system, it might be a good idea to turn on verification again to be sure all is still well.

2) Not all problems with Ghost are the fault of Ghost - things like drivers can very definitely be a source of problems

3) The latest driver is not always the best driver!

In my case, the driver details are as follows:

Atheros AR8121 NIC

The driver that was failing came from the Atheros version 1.0.0.49 package. This package contains drivers for DOS, Win XP, Vista, Win7, etc. The Windows 7 64-bit driver I was using from this package had a version of 1.0.0.22

.

The older driver which works fine came from the package with version 1.0.0.47 and the Win7 64-bit driver is 1.0.0.20.

Re: CRC Validation Errors in Ghost 15 and How I Solved It

Hi Hannes,

Welcome to the Norton Community.

Very well written post and I commend you for writing this.

This is a pretty common error reported on the forums and generally it points to an issue with either reading from the source drive or writing / reading back from the target backup drive. Which one Ghost is referring to can usually be determined by the exact wording of the error message and using or not using the Automatic verify option in the backup job.

Most common causes for this I've seen are:

  • Hard drive errors which can be resolved by running chkdsk /r on the source or target hard drive as applicable.
  • Hard drive problem where hard drive ends up needing replacement.
  • Bad RAM
  • Driver problems as you experienced and congratulations again on isolating this.

Thaks again for posting this.
