Hi, I was having trouble getting a file from a cd because I kept getting this CRC warning so I download a program called CDcheck which works wonders...

http://www.softwarepatch.com/software/cd-recovery.html

It continues to copy the file even after the CRC warning and it also works by copying from one destination to another on hard drives or folder to folder. It also gives you a detailed report of how many errors you recieved so that you can, for example, clean the cd and see if you get less errors which would mean more data would be recovered. Very usefull program I do recommend.

Leo, thanks for your help on this. I tried all of the above when my Outlook began having problems. It didn't work. Amazingly, I did the following:

1. Did a simple Disk Cleanup.
2. Used a utility to clean up the registry.
3. Believe it or not, DEFRAGED the harddrive.

Outlook is as good as new. It must have moved the file off of the bad areas. I did a diskcheck and yes, I had a bad areas. So now it's going to be, clean up the harddrive and get ready for a replacement, just to be safe.

I just wanted to pass this along.

I tried the xcopy but it gave an "Access denied" message. Also if I try the chkdsk first, and if that doesn't recover everything, can II still use spinrite later or will I have changed the structure of the file and therefore loose any chance to recover the rest?

I tried to do the procedure using the dos prompt to xcopy /c my archive.pst file that had been giving me crc errors. the xcopy /c command resulted in 0 files copied, crc. Any thing else I can try to recover this archive.pst? Thanks.

i recovered my data by this software CDCheck 3.1. It is free!

my system saying eror and to run chaeck disk
but when i run chkdsk on windows and ms dos it says it will be done at system restart but it not don what to do
pls can any body help me

Hi again...A follow up to my post of October 8.

That fix didn't work long term, the Outlook.pst because corrupt again.

I believe I have a real fix for the Outlook issue. After going after many of the solutions xcopy etc, I decided to try something very basic. I exported each section of Outlook ie Calendar, Contacts...etc...etc. to a seperate file outlook calendar.pst etc on a seperate hard drive. I had 2 HD's in the system and plan to trash the bad one, only using the 2nd HD in the system once it's reformatted. I copied each folder seperately. To test it, I imported each of the pieces to the Outlook Archive file and it worked perfectly, all of the information is in tact.

One other interesting note, for those that mentioned their Outlook.pst is over 1 gig, my corupt file is 1.19 gig, the archive.pst file is only 128 meg. I guess Outlook does a great job wasting space.

I am going to move both the seperate files and the archive.pst to the new Outlook once the machine is totally refreshed.

Good luck.

LEO, I'm having huge problems with this CRC error. I can't install corel draw which i really need right now, and i'm installing it from free downloaded trial version from OHP of Corel. I'm having the same error, when i try to check my large format photos in a folder. My laptop just stops for a while.
And when i download some files and try to extract them using WINRAR, i get the same problem.
I've done the register cleaning, scanned with antivirus programmes.
I repaired my Windows XP for the 5th time now.
PLEASE HELP!
