THE OVERALL GOAL HERE IS TO MOVE THE EMAILS TO A NEW PC. My question is whether a defragmented disk can cause a Cyclic Redundancy Check (CRC) error in Outlook OR that error is NEVER related to a fragmented disk. PLEASE NOTE THAT how to get rid of the error is secondary here. I have the MS KB article on how to address this error, please DO NOT reply with the link to that article !!! The reason I am posting here is I suspect that that KB article (at http://support.microsoft.com/kb/319128
and then http://support.microsoft.com/kb/287497
) only works if the problem was caused by improper closing of the pst file and will NOT FIX the problem if it was caused SOLELY OR PARTLY by a highly defragmented disk. Because after running chkdsk and scanpst.exe YOU STILL HAVE A HIGHLY DEFRAGEMENTED DISK.
NOTE: The HD in question has only 7% free space left.
BACKGROUND: I get Cyclic Redundancy Check when I try to copy my Outlook.pst file (1.4 GB in size, Outlook 2003, Windows XP SP2) on my OLD PC. I also get the same error when I open some subolders in my Outlook email but do not get that error on other subfolders. I sometimes get that error when I try to EXPORT the emails but mostly not.
I also get a message whenever I open Outlook that the outlook.pst file has been improperly closed and needs to be checked. Then there is a 3-5 minute delay with a progress bar while it checks the pst files and then Outlook starts and the email is displayed. If I then close Outlook and reopen it I STILL GET THE SAME ERROR. OBVIOUSLY THIS ERROR IS RELATED TO THE CYCLIC REDUNDANCY CHECKS, RIGHT?
And YES the pst file has been improperly closed many times in the past because if the PC is connected to the internet, Outlook freezes and then the entire PC freezes as soon as Send/Receive starts. So then I must abrubtly power down the PC which means the pst file was improperly closed.THE ABOVE RESULTS ARE ACHIEVED ONLY by pulling the ethernet cable out of the PC so Outlook does not freeze.
Now if I EXPORT the entire pst file (checking the Include Subfolders box) and import the result on the new PC, I FIRST from the Export, get a pst file that is 1/5 the size (about 300 MB) of the original pst file and sure enough when I look in Outlook on the new PC, many many emails are missing.
SO PLEASE DO NOT REPLY THAT THE SOLUTION IS TO EXPORT. I ALREADY TRIED THAT !!!
OK, why do I think that the problem is that the HD is fragmented given the error at opening Outlook about the pst file was imporperly closed?
(A) Because there is ALSO an older Outlook.pst file dated 1 1/2 years ago that DOES COPY AND DOES NOT HAVE ANY CRC ERRORS ASSOCIATED WITH IT. When this file was current there was 1.5 more free space on this HD meaning it had about 20% free space.
(B) When I Export (old PC) and then Import on the new PC I notice that the missing emails are all from Sept. 2006 to March 2007. i.e As the file got bigger and bigger (later dates) the HD got more and more fragmented so it is the later-in-time emails that are missing because they are the ones with the CRC error. NOW THIS POINT (B) IS ONLY A THEORY but it is a theory that makes some sense.
MY CONCERN IS THAT IF THE CRC ERRORS ARE CAUSED BY A HIGHLY FRAGMENTED HD, THEN THE MS KB ARTICLE APPROACH (RUN CHKDSK /F AND THEN SCANPST.EXE) WILL NOT WORK.
Please reply if you know the answer.
