Cyclic Redundancy Check Error - Vista Backup

Hi Experts,
I have a user (CEO) with a Sony Laptop running Vista Business.  For several months now his backup has reported failing due to "Data error (cyclic redundancy check). (0x80070017)"  when trying to backup to his network share. I have seen some compressed zip files within his backup area, but cannot determine what has, or has not been backed up or at what point the backupfell over.
I have read many posts about this type of issue but nothing definitive as to the cause.  I have instructed the user in the meantime to a) defrag, b) begin manually copying batches of his important data over to his network share, followed by manually copying over his archive pst files for Outlook.  I am now trying to arrange to have his laptop available for a few hours next week to work on this problem.
Can anyone provide me with a step sequence to follow to try and address this issue, please?
Thank you.

Hi,

Try this solution:

Click the Start button , type cmd in the Start Search box, right-click cmd.exe in the Programs list, and click Run as administrator . If you are prompted for an administrator password or confirmation, type your password, or click Continue .
 
At the command prompt, type Chkdsk /R X: (where X: is the Drive Letter for the volume you want to check), and then press ENTER.
 
Press Y when you are prompted to check the disk next time that the system restarts.
 
Close all applications, and then restart the computer.

Note During the restart process, Windows checks the disk for errors and then starts.
 
After the computer has restarted, repeat the process for the other volume and then rerun the backup operation.
 
If this fails follow this guide:

Hi,
I have always had issues when trying to back up to network shares in the past. either it wouldn't recognise the share or it would but wouldn't accept the password when trying to backup etc... now if i want a backup of files on local pcs i use microsoft synctoy which can be downloaded from here http://www.microsoft.com/downloads/details.aspx?familyid=c26efa36-98e0-4ee9-a7c5-98d0592d8c52&displaylang=en and with storage being so cheap i think this is a good option for some users like CEOs who like to know that there data is backed up.
You can even schedule synctoy on the pc to copy the files on a daily or weekly basis etc....
Regards.

Hi,
Thanks for the responses.  I am (hopefully) scheduled to get the CEO's laptop next Thursday, so will not be able to try any of the suggestions until then, so things will go quiet for a bit on this.  But I will report back when I get some more info / success from suggestions.

Thanks in the meantime.

Hi,
I've been put off doing this until Monday next week now.  Just thought I'd keep you up to date.
Thanks.

Hi,
I have been delayed yet again by the CEO.  It now looks like I won't get to do this for a couple of weeks due to summer holidays, etc.  I feel that the response by pcfreaker answers my initial question - ie a roadmap to do the chkdsk, etc.  So, instead of delaying things further I propose to accept his answer and award the points to him.  I'll then come back and update should the problem still exist.  Does this sound okay, or is there another protocal I need to follow here?
