Backup on one machine fails at 52% RRS feed

  • Question

  • I had a Windows 7 64 bit machine backing up regularly for the last year.  I recently had the system die and because it was my son's machine and may have been virus related, I decided to reinstall Windows 7 as a new install, but kept the windows.old files on the C drive.  Now I've reinstalled everything, I have the connection software, but when I go to do a backup of the C drive, it fails after locating clusters that have changed.  I will cut and paste the error below, but other information that has me baffled.  I have the main drive partioned into two drives.  One called Recovery which has the Alienware files for a default installation and then the C drive which has the OS on it.  When running the backup, it will complete successfully if I uncheck the C drive and it will backup the recovery drive and any USB drives that I have connected.  It only crashes when it tries to backup the C drive.

    Any ideas?

  • Can I ask why you did a fresh install rather than a WHS restore?

    This suggests a hardware error, probably a failing HDD, as the source of the initial problems. Try replacing the drive and restoring from your server.
    I'm not on the WHS team, I just post a lot. :)
