Fixed: How To Fix Data Errors In Outlook 2007 Cyclic Redundancy Check.

Over the past few days, some readers have reported data errors in the Outlook 2007 Cyclic Redundancy Check. A circular redundancy check is a data error that occurs whenever Outlook has a serious problem downloading recently found emails to the local computer. Factors causing CRC errors in Outlook, be it a corrupted PST file or a change in location on your hard drive.

Cyclic Redundancy Check (CRC) dilemmas indicate errors in a specific file and in many cases pertain to your hard drive.

There is no problem with Outlook itself, but there is still a problem with the location of the personal PST file on the hard drive.

If this happens after the client has just copied the pst file (to floppy, from the network, from CD, via download), you should first check which original source is still working and then try to copy it again … If it “happened all of a sudden,” as everything worked without moving yesterday, the problem could most likely be in the software or hardware.

Problems With Software Hard Disk

If the problem is with the software, you can usually start it byby running chkdsk (CheckDisk).

  1. Open a fantastic command session with elevated privileges. For example, through;
    • Right-click the Main Window tab and select; Windows PowerShell (Administrator)
    • Often open the Start menu and type Windows; PowerShell.
      Click the result with the right mouse button and select “Continue”; Run as administrator. Type
  2. in a date command; chkdsk c: / f
    • Replace “c:” with the letter of the drive where the pst file is located.

If it tells your company that it cannot scan right now, I would say hard drive and ask if you want to scan hard drive with restart, select Yes (Y) and change computer.


The chkdsk command is definitely like a first aid kit for hard drive problems. You

When you’re done, drag scanpst.exe to your pst file if fixed.

Hardware CD Problem

If the problem is hardware related, you will likely find disk scan errors in the system symbol of your Event Viewer. Presently ;

  • Right-click the Windows Start button and select; Viewer
  • start-> type of activity; Event Viewer

Unless you have a very old hard drive and / or motherboard, they will most likely become S.M.A.R.T. If so, you can configure a utility to monitor the health of your hard drives.

I use SpeedFan a lot for this because it’s free and it also monitors your system’s temperature and hence fan speed (wow, where does that name come from?). However, many motherboard and hard drive manufacturers also have their own tools to check for hard drive degradation.
