Several people have noted that XCOPY does not, in fact copy files with CRC errors, to which Leo responded

"Folks, PLEASE read the article. The whole article. It's pretty clear:

If this copy fails, then we've confirmed that the bad sector on your hard
disk is actually being used by some portion of your file."

Leo, PLEASE read your own article, to wit, the context of the sentence you took out of context was when copying to NUL, not when using XCOPY:

"
C:\wherever>copy Outlook.pst NUL
1 file(s) copied.

This reads the entire file by copying it "nowhere". If this succeeds the problem is not actually with the file itself, but the location you were trying to copy it to. My recommendation would be to copy it to a different disk entirely, or a different machine on your local network.

If this copy fails, then we've confirmed that the bad sector on your hard disk is actually being used by some portion of your file."

AND...

"Two important things to note here: we've used the xcopy (for eXtended copy) command, and we've added the "/C" switch which keeps copying even if errors are encountered. As you've already experienced, the default behavior of both COPY and XCOPY is to stop if an error occurs.

Now that we've got a "no worse than" backup copy, we can start attempting to repair the disk. "

All of this was a discussion of recovering a single file. You failed to recognize that XCOPY skips a file with a CRC error and keeps copying OTHER files, rather than stopping altogether. This is irrelevant when attempting to recover a single file.

Just quick message to Rob, I would start to break out that PST into several, perhaps by year. In my former life as an admin, I know that when you start to approach 2gb size in PST files they tend to corrupt very easily.
I used to break out users' PST files by 2002, 2003, 2004, etc, leaving the last two years or so in the current PST file.

Also, thanks for the article, it was helpful

I purchased a program that has an application CD and an application update CD. Then there are 6 CD's that install the data. Mostly .cab files that contain large single files that are spanned. When I get to the 5th CD, there are two cab files. one contains the remainder of the 4th CD spanned cab file and the beginning of another cab file that spans to the 6th CD. When installing, the 5th CD stalls just before the end of the cab that flows into the 6th CD, but then it pops up a window that says installation complete. it doesn't ask for the final disk and I can not access any of the data or the program at all. If I try to copy the cab or extract the file it contains, I get Cyclic redundancy error. If I copy it from cmd prompt with a c switch, it still errors CRC because it's all one big file. I tried an error fixing program that got through the file transfer to HD, and I burned it to a new disk, but it still is premature installation and won't work. The file in the cab is called rfile002.001 and spans data5.cab (disk5) and data51.cab (disk 6). any ideas? I know it is the 5th disk and not my drive.

Dear Leo,
I am out of ideas!

I have 1 disk 2 partitions. Back-up C: to D: with Ghost works fine. Have done it multiple times. Also Wondows / properties / Chkdsk does not find a problem. This would indicate no problem with the hard drive.

But - back-up to DVD, I get a CRC error on the last DVD consistently on both DVD-R & DVD-RWs for either partition. Got a new DVD, still get the error.

Ran “ignore bad sectors” and it seems to work.

Tried using Nero-7 backitup, still copies to multiple DVDs then fails with CRC error at the end.

So disk to disk works, but disk to DVD fails on two DVDs in the same manor and after creating first 3 DVDs correctly but on the end of the 4th.

If it’s the hard drive, why would it work disk to disk. If it’s DVD, why always on last DVD and on different DVD drives. Should I be looking at cable, mother board, etc.

I have not tried to connect the DVD as a secondary drive on the first IDE cable yet.

Many thanks,
Clark

Thanks for the tips! My users OST file was corrupted and I could not copy it to "null". Since we are lucky enough that we keep it on the server, I was able to delete his ost file and it re-created itself when I reopened Outlook.

Hello leo.
I'm trying to reinsall win-xp-pro,but i keep getting this error,(data error cyclic redundancy,one of the components that windows need could not be installed).How can this problem be fixed? And how can i fix this problem if there's no operating system on my (ACER ASPIRE/5050 LABTOP)? Because i'm stuck,it started 1/2way and stopped,so now i'm stuck with no os. please help me.Oh,and also i tryed to use my recovery disc,and it went 1/2way and an error poped up please help me.

At times a file or software being downloaded from the internet may get corrupted . The corrupted file or software will not work and will give the cyclic redundancy check data error when one tries to delete it from the hard disk. Running CHKDSK can help in deleting the file or software completely.

I have bought a WD passport essential (250 GB) external hard disk! There were some setup files (included software with synchronization and recovery)....even I didn't removed or replaced these files in WD, I tried to copy and nothing (cyclic redundancy and some I/O errors-even the usb ports are well installed -no driver problems)...then I have formatted it, and still the same problem ...Also, I read and proved your advices, and still :( nothing...Please help me, because I spend a lot of money for this device and I cannot use it.....
