DVD shrink Data Error (cyclic redundancy check)

You can try toothpaste to lessen the severity of scratches.

Yep, just put a small dab directly onto the scratch, use the traditional white variety not the clear gel type. I then use a soft tissue wipe gently in only a radial direction (a straight line between the hub and the rim). Since the data is arranged circularly on the disc, the micro scratches you create when cleaning the disc (or the nasty gouge you make with the dirt you didn't see on your cleaning cloth) will cross more error correction blocks and be less likely to cause unrecoverable errors.

If you continue to have problems after cleaning the disc, you may need to attempt to repair one or more scratches. Sometimes even hairline scratches can cause errors if they just happen to cover an entire error correction (ECC) block. Examine the disc to find scratches, keeping in mind that the laser reads from the bottom.

There are essentially two methods of repairing scratches:


Fill or coat the scratch with an optical material.

Polish down the scratch.
There are many commercial products that do one or both of these, or you may wish to do it yourself with polishing compounds or toothpaste. The trick is to polish out the scratch without causing new ones. A mess of small polishing scratches may cause more damage than a big scratch. As with cleaning, polish only in the radial direction.

 

well i dont have regular toothpaste i got the gel kind

 

I need help, I have been using dvd shrink and having no problems. No I tried to copy one and got an error. I feel it was cause of encrypt.

So I used dvd decryp. and copied it to my hard drive. When I tried to crunch it with dvd shrink or neur. I can not pull up the files. Keeps saying not found. What am I doing wrong. Please help me. I am not that great with computers!

 

hootfour, what is the exact error message you are getting? Is it a Cyclic Redundancy Check error message?

 

I guess hootfour doesnt need help. Dont spam the forums hootfour
asking questions then you dont follow them

 

hootfour,

Let's post in English not PC code . . .

If you ripped in the ISO mode then open Shrink, go to File - Open disc Image and browse to where you ripped the file and Shrink will pick it up -

Cheers,

Pete

 

I never did get that one disc copied, i guess there are some discs that are just corrupted someways. It was my friend's disc, ill have to get another copy from the movie store and copy that one.

 

Follow the directions in the guide in my sig to clean the disc BUT Before you do, Go into DVDD, Tools - Settings - I/O tab - "Tick" the box at the bottom where it says "ignore read errors" and try it again -

Cheers,

Pete

 

i meant to post this here originally not start a whole new thread...

Hi everyone, I'm new here but I've been using the forum to fix some of the problems I have encountered in the past. Typically I can just copy the DVD file with DVD Decrypter, and then open it with DVD shrink and procede like normal. I have tried to do this with the Spanglish DVD, and encountered a problem where it "Failed to Read Sector" and I ended up skipping that file. After it completed I tried to open the Files with DVD Shrink and it would not open because it stated that a VOB file was missing. I saw some of the tips before and am currently trying those...I just noticed how long it is taking..and the number of errors(46 read errors), so I am not sure if it will work...I tried to do it the regular way with 2 different discs, and have encountered the same problems. I was just curious if anyone else has encountered these problems with this DVD and if they were able to go around them....Thanks for any and all info.

 

DreDaze, Spanglish had some bad pressing. I suggest you return it for another copy. Preferably from a different store. (If Wal-Mart got 50 Spanglish DVD's, chances are is that all 50 will be bad.) I backed this movie up no problems using DVD Decrypter 3.5.4.0 and DVD Shrink 3.2 .

 

I had the same problem and It acts like the disc is dirty or scratched but it wasnt. Just exchange for a nother one

 

hi guys - new user here. Ive been researching the error I get when trying to shrink and I came across your forum.

Here's what happens:
After I Rip to files using DVD Decryptor I then launch Shrink.
When I go to Open the Files I get the Follwoing error (similar to above)


DVD shrink encountered and error and cannot continue

Failed to open file C:\\xxxxx..\\VIDEO_TS\VIDEO_TS.vob

This system failed to find the file specified.

I know the file is there coz I checked the folder. I was able to burn one movie successfully. Then I tried three more all with the same result although one time the file not found was VIDEO_TS.ifo

Its driving me crazy. Ive rebooted..gonna try a reinstall..then i dont know..any help would be great!

 

You s/b ripping in either the File Mode OR in the ISO Mode.

Also, you should be be using the DVDD 3.5.4.0 version of DVD Decrypter. Earlier versions won't be able to rip Spanglish.

Finally, let's take a moment to fine-tune your DVD Decrypter's settings. First, it should be version 3.5.4.0. Go to "Tools", "Settings", set everything to "Default". Then in the "General" tab change, "Removal Method" from "Normal" to "Aggressive", in "File Mode", "tick" Remove IFO - PUO's." For ripping in the "ISO, Read Mode", "tick" "Remove IFO PUO's" there also. in the "CSS" tab, under "CSS Cracking Method", choose "Brute Force ~> I/O Key Exchange" and "On Failure" choose "Yes". . IMPORTANT: In the "I / O" tab, in the bottom right, "tick" the box which says, "Ignore read errors". This helps with some Mfgr defective discs and it is an excellent setting for dealing with lightly scratched discs which may cause reading problems. We're now finished with our settings here so click "OK." There's no reason to change these settings. DVDD is good ripper right out of the box, all we did is to give it some "teeth." (Lol

Now give it a try,

Cheers,

Pete

 

I actually get this error when attempting to copy MP3 files to my computer from a CD-R disc. However, I burned the CD-R disc as a data disc, and I think that is the cause of the problem.

How do I recover the files now? I tried using CDCheck software, and used their Recover option but it merely froze every time and the DVD/CD-RW drive kept on making a grinding sound.

 

sherbet80

It sounds like your drive is dying.

A bad disk doesn't make the drive grind and neither does a bad file.

I would try that drie in another PC and if it made sounds there, I'd buy another.

(Actually, if it were me, I would trash anything that made a "grinding" sound in my presense.

G' luck,

Pete

 

Actually, I just bought this laptop a month ago, and no other CD's have caused it to make this sound. I describe it as a grinding sound, but it's really the kind of sound that is made when something can't be read. Does that make sense?

 

Is the "disc" scratched or dirty?

A CRC (Cyclic Redundancy Check) error is DVD Shrink's and/or DVD Decrypter's way of telling you that it cannot read the disc (DVD). It is caused from the disc being to dirty (fingerprints, smudges, etc.) or being to scratched. First, try cleaning the DVD. You can try toothpaste to lessen the severity of the scratches. (By no means am I saying that you will totally restore the DVD back to original condition, all your doing is just trying to get DVD Shrink to successfully read it.) If DVD Shrink or DVD Decrypter still generates this error message, I suggest returning the original for a different copy.

I burned 6 of these discs the same way - all mp3 files as data discs - and all of them have the same problem. I burned them only two days ago, so I doubt that is the problem.

 

Ok. This is for Pete or anyone else.

I'm trying to make a back up for Harry Potter and the Chamber of Secrets and that same error happens to me at 97% of analyzing using Shrink (the redundancy one)

Using dvd decrypter, it shows taht same reading error at 97% as well (ISO reading) and this happens even after I changed my settings to the ones Pete mentioned.

I've also cleaned the disc using the methods explained previously as well and I'm pretty sure the defect is at the very edge of the disc somewhere. AND i've also tried to rip it with shrink by lowering the target size to 4300mb (and lower) but to no avail

Anyway, my last resort was to use DVD decrypter and IFO it, at 97% again, it keeps on retrying and retrying so I abort the job, and then delete that VOB file it couldnt finish (This is the end credits so I'm not worried). <-- I used this method http://www.doom9.org/index.html?/dvddec.htm

Also, the files DVDD created i stored into a folder named VIDEO_TS stored in a dummy folder with an empty AUDIO_TS folder (like the guide says)

HOWEVER, when I open DVD Shrink > Open Files > dummy folder it shows an error about failing to open C:\.....folder\VIDEO_TS.IFO
"system cannot find the file specified"

**Another point, when i tried to do the IFO method for a previous DVD, the same error occured even though the dvd had no problems (it worked the ISO way) So I'm thinking its something with my way of using DVDD IFO

ALSO, another method I tried after decrypting files was making it into an ISO using this guide http://www.afterdawn.com/guides/archive/burn_dvd_folder_dvd_decrypter.cfm

However, When I try to open it in Shrink, an error message saying it cannot find VIDEO_TS.ISO

?????? this is driving me crazy

any help is much appreciated.

 

I'm beginning to think that although I've deleted a VOB file (end credits), that is not the problem - the real problem is the method for ripping IFO using DVD Decrypter and then opening it with shrink

The same shrink error of not being able to find whatever.IFO occured to a perfectly fine dvd I burned using the ISO method
