Cyclic redundancy check error

Hello everyone,

After trying countless recipes found here and there on the forums regarding this infamous cyclical redundancy problem, all without success, I simply cleaned my CD with a soft cloth and there, MIRACLE, HALLELUJAH, it works.

A word to all those who might be tempted to use this method, it is now protected by copyright and I will not hesitate to take legal action against any infringer.

Best regards,

Hello,

you will need to try with Alcohol 120%. Either by making a direct copy, which will create an image file that you'll need to mount later, or by using the "Xtra Assistant" to select each file individually. If you're not familiar with Alcohol 120% yet, it will take you some time to get used to it, but it's worth looking into.

In case there are issues, it's best to use this assistant and make an "image" backup of each part of the movie - if that doesn't work, I don't know how to proceed - then mount the "image" file created by Alcohol 120% in the Daemon Tools software (free).

You can try disabling AnyDVD or changing the region in the menu by checking region 1 (USA, etc...) instead of region 2 (Europe, etc...).

There’s also a software called "DVDFab" that can sometimes work.

Be careful, if during DVD playback - if it's a DVD - you see little green squares (pixelation of the image), it might mean that the original is damaged. You may then use AnyDVD Ripper with the following path: start, programs, Sly Soft, AnyDVD Ripper, or "rip the DVD".

If you're working on Vista, try using XP instead, you'll encounter far fewer obstacles in this kind of operation.

Good luck.

Your question is redundant; it has already been asked.
In any case, it comes back in a cyclical manner.

And Google finds the answer:

cyclic redundancy error = corrupted data.

The CD is probably damaged, or it is copy-protected.

I have a cyclic redundancy problem; every time I try to reinstall Medal of Honor: Allied Assault during installation (at 11 percent), it says error: cyclic redundancy problem.

I had the same problem...
For me, it was simple, instead of dragging the file, just do a copy and paste.

Cyclic redundancy is in the messages of this discussion :).

The cyclic redundancy check problem often occurs when the "Lead Out" has not terminated properly.
This problem occurs on certain file systems (including DVD and CD-ROM) that allow a higher directory to link to a lower directory (with the files from the higher directory actually contained within the lower directory).
If certain data is not written correctly, the computer will point to the lower directory, will see itself, will point back to itself, and thus return to the lower one.
This creates an infinite loop and is called a cyclic redundancy.

After long hours in front of the screen, I finally managed to get rid of the infamous "cyclic redundancy," without formatting!!! I'm not a fan of formatting or defragmenting; I know many are keen on it!! lol!!
Here's my story:
"Take the time to read carefully, even if the terms are not quite accurate, (it's for better understanding)"
The PC was working wonderfully until the day my kid, in the spring of his life, having crashed his own, went surfing on "exotic" explanation sites, if you catch my drift!!!!
Oh damn!!!! A mess on the computer!!!!!
Hard to shake off; it’s been 4 years since it has run without a single format or defrag, and just one problem a year that I managed to counter, but this time I decide to do a bit of housecleaning, I back up everything I can, "docs, photos, and personal files" so I don’t lose everything, then I try to make an image of the HDD, a first for me!!!
It must be said that following a crash three years ago, I have two other already configured HDDs on standby; yep!!! No more than 5 minutes to get the machine back up and running in case of issues!!!
From time to time, I "plug" them in for updates
So after downloading what I need to make this famous "photo," I dive in!!!!! The program interrupts.... and the damn message appears "rebounding in loop"!!!! lol
A little chkdsk!!! ..... "defective sector"
Yes, but where????
I restart Drive Image XML, and the error is located between the 863,645th and 924,843rd sectors!!!! out of the 77 million on the partition; the haystack is smaller!!!!
And there I make the mistake of doing a defrag!!! which aims to tighten the bytes, but which makes "cohabitate" the black sheep right in the middle of the flock!!!!
I need to locate this sector, so I launch "WinHex" and go see in the "little haystack" what’s inside, .... a DLL!!!! I make a copy and then move it to D:.... then I put it back in its original folder \windows.....;
I restart DrvImXml, and the haystack shrinks to 561 sectors!!!! I’m going to get it!!!!!
With WinHex, I locate the sector, but I can’t edit it; my version of the program is a demo and doesn’t allow saving to the HDD,
for info, filling all bytes with "00" equals a low-level format, yes but only if it’s done on the "physical" surface of the HDD and not on the "logical," there’s a "shift"; be careful not to confuse it!!!!
I then try another hex editor, but this one is too "innocent"!! It only reads the "logical"!!!
And then an idea!!!! I start an examination with the disk tool of my HDD, a 80GB Seagate, therefore "Seatools" on the "Ultimate Boot" CD...
A complete analysis allows me to locate the erroneous sector, plus that’s where I saw the shift between the physical and logical surface!!!
Seatools leaves me at the end of the analysis the option to fill the sector with "00" or not!!!! I hesitate, then on the second analysis, interrupted by me because it’s dragging on, I "zero" the sector!!!!
BINGO!!!!!

Conclusion:
It is not mandatory to format an HDD just for a few defective sectors if the physical surface is not affected!!!!!
I was able to see that deleted data remain on the HDD
and above all that with a little effort, you can make it happen!!!!!

Thanks nonetheless to the forum team

Hello

I found this too, if it can help clarify things for you

"In computer science, a cyclic redundancy check or CRC (Cyclic Redundancy Check) is a tool used to detect transmission errors by adding redundancy. The added redundancy commonly referred to (incorrectly) as a checksum is obtained by a type of hashing over the entire data set.

CRCs are calculated before and after transmission or duplication, then compared to ensure they are the same. The most commonly used CRC calculations are constructed in such a way that errors of certain types, such as those caused by interference during transmissions, are always detected."

Hi

Well, well, this topic has lasted quite a while!

Since it was started…

First of all, I believe that with a good cleaning of temporary files and the registry every day (not just as some say "oh once a month is enough!") this problem doesn't arise.

I have only had this problem once since 1999 with my first PC, and since then, I've been using Ccleaner and RegCleaner and haven't encountered this problem again...

So maybe we shouldn't overthink things and get into some routines...

Have a good day

I also encountered this problem with the Tambe Reader game.. the issue is with the disk itself due to the alteration of 1 file.

Good evening,

first of all, run a memory test with Memtest 86 v.30

Otherwise, your problem is most likely due to the copies.
Speed too high or poor quality of the CDs.

Hello,
I have the same problem of cyclic redundancy, I can't read some of my DIVX, but if I lend a DIVX with a cyclic redundancy to a friend, he can read it. Where could the problem come from?

I had the same problem, I managed to work around it by restarting my machine.

Hello,
I would like to know why I can no longer see my photos on the floppy disk.
Every time I try to view a photo on my floppy disk, it says "cyclic redundancy check error."
How can I see my photos on my floppy disk????
Thank you for your response.

try to copy your diskette to another one, it has worked before
good luck
a clever person can play the fool, the opposite is not
possible

Hello,
How should I go about copying a floppy disk??
Because every time I want to remove a photo from my floppy disk to put it in a file, it says "cyclic redundancy error" as well
thank you for your reply

hi

I have the same problem, I tried to burn a CD, and at one point it gives me a cyclic redundancy error.
It annoys me, I would really like to burn it.
Actually, I really want to copy my DivX onto the drive, but it doesn't work.
