Hi Leo,
I have a problem with my DVD writer. Actually it reads only, but can not write any DVD disks. Another thing is once I insert blank DVD, it take a long time to open it.

Thanks in advance.

Try JFileRecovery (free on the net), it wouldn't correct the problem but you'll be able to still copy the files, even bad. In some bad files of jpeg format, you can still see the image and even correct it manually (photoshop or something) if you want it badly. This is better than nothing in case you can't get the original drive that copied the file. Good luck.

ps: i did get this error from my dvdcam recorder, and i understand the 'centering' issue about the disck been writen, and then trying to reread on a computer drive...:S

Movies will play with CRCs no problem but they won't write. We need to disable CRCs during the write. Any ideas?

I am getting a CRC error on a DVD with .NEF (Nikon RAW) photo files. For at least some of the troubled photos the thumbnail shows up, and Adobe can open a larger version as well so there must be enough data for that at least. Only it won't let me COPY what I DO have. Some of them don't display thumbnails; I assume these are lost causes - there may have been some dust exposure to the burner that wrote the DVD which could have corrupted the totally lost files.

Leo, I need your help. I had copied some video files that I had purchased off a website and burned them to a c.d. Now, the c.d. worked fine but about a year later, I'm getting the cyclic redundancy message. I think my first mistake was using memorex c.d.s as I've used the Sony brand and they haven't been giving me any trouble so far.

I've tried everything: copying files to my desktop, to a folder, burning to DVD (I've lost three so far because of the error message) and I've even tried windows media maker on my desktop and laptop to try and save the video files. This isn't the first time this has happened to me and I'm trying to avoid erasing the disc altogether as I spent a lot of money obtaining these video files. Is there any way to save what I have without erasing everything?

Hi all,

SOLUTION: I also had problems with the CRC error when burning games. My try has been with two .rar games. What I did what was just to descompress the total file.rar into my PC and to install the games directly from the given data,through the setup.exe , without burning the game.
When I was installing the game from the DVD I was getting the error but the same file descompress and installed without burning had succesful results. I hope it can help, though I know my comment is not very professional

CRC errors can also be caused by IDE cables being too close to each other, or too long.

Dear Leo,
I have tried everything recomended on this site about CRC. But nothing works. My friend said that he would let me borrow a DVD for a week with some files and pictures of his trip to places around the world, and I was so excited because he gave me permission the make a copy so I can keep a copy. But when I tried to copy it, "Error, Cyclic Redundancy Check" pops up everytime. There isn't an scratches on the disk, nothing's wrong with my computer DVD drive reader. I even tried to copy the file on my other desktop and my second laptop, but nothing. Please help:(

i have just finished backing up over 200gb of my files onto dvds only to find that i have been burning CRC errors into many of the discs, is there any QUICK way to test files readability so i can create a list of whats bad and whats not then get the bad files reburnt now the problem is fixed. ive tried CDCheck & IsoBuster they take forever to read the bad files. i need something that can just knock up a disc review quickly is there such a thing?? or maybe a way of reducing the amount of time windows spends tring to reread the bad info? so i can test the discs myself or am i better off starting from scratch?

The only answer I know of for the CRC error, is to download and use CDCheck on the CD or DVD. It reads and re-writes the whole CD/DVD, to a new folder, until it gets to the problem area. Then, it reads it, sector by sector, and stamps a "0" in an unreadable sector, until it finishes reading the "BAD" part of the CD/DVD and repairing it that way. This works for scratches and other errors on the CD/DVD that causes a CRC. (I think it works for computer files, etc. but I've never needed to try this.) Another trick is to copy all the files with Windows Explorer/My Computer, and only run CDCheck on the file(s) that produces the CRC. Then, from the folder that the repaired and copied files are in...burn that like it was a CD/DVD...this is just faster, CDCheck will do it all for you, it just takes a little longer on files that don't need repairing. Using AnyDVD, in the background, allows one to do this to any copy protected CD/DVD, as well. It works GREAT!!! Good luck and enjoy repairing your messed up CD/DVDs. :-)

i have similar problem, i was having problems with my laptop, took it to local bestbuy for fix, i purchase backup discs of my hard drive so i wouldn't lose any info.. well the laptop was fix and is working perfect. but now when i try to copy or reload my backed up files for discs(which are "DVD+R DL double layer 8.5 GB RW") i get the the "Data Error-cyclic redundancy check". when i first load the DVD discs my disc drive immediately begins to click & whirred after a couple on minutes of this files & folders appear, but as soon as a click any folder the whirring begins again and the folder eventually opens. once i get to a file i want to open/copy it whirrs again then i get error. the disc aren't scratch & i have clean any way, even tried running disc thru "cd check" software program it wasnt able to read them. The best buy personell said my dvd/cd rom drive was reading them to slow, and that was cause for error and i just needed a faster drive to get files. i have a toshiba DVD-rom SD-R2312, it it operates perfectly while watching dvd's or burning cd's.. please help

If you suspect the CRC is because your cd is scratched use JFileRecovery to copy. NOT FOR EXEs but if its music or video you're trying to recover (assuming the cd is not broken in 8 places) its a miracle worker.

I get CRC error when I try to read the dvd disc that I just burned. But the problem is when I try to burn the compilation again I get the CRC error again on the particular files that I was getting before. Is there a problem with the hard disk?

You might mention that you can also get a CRC error on SD cards... and various other media.... not only CDs/DVDs.

Hi Leo
I read the articles above about CRC on CD drives but my problem goes beyond. I recently upgraded my hard drive and motherboard. I installed a game and after going through a few of its menus it freezes and windows gives a CRC error. Also the same error persists with other functions. I tried to download a large file, it took 9 hours to download. After the file download finished and it was ready to be copied on the hard drive a CRC error appeared. Could the problem be related to my hard drive becuase I had none of these problems before upgrading.

PS How do I read the replies you give to commenters

Hi Leo...

Nice site... and let me put this to you to continue this thread about CRC:

I've just got a new laptop from Dell... it has XP Prof SP2, up to now I've been using XP Home SP1 (deliberately did not "up"grade to SP2).
Many files which are on DVD which I need to copy over are being rejected by the new machine's drive... back at the old machine they are accepted fine... but when I run CDcheck on the old machine errors are indeed flagged. Is there sthg about XP Prof (SP2) which would account for this... and more importantly, is there not some way of tweaking XP Prof SP2 so that it is less puritanical?

Otherwise presumably I'll have to reformat, install XP Home SP1 on the new machine and struggle to stop Micro$oft inflicting its hateful "up"grades on me and causing me even more Micro$oft-related stre$$... than normal?

Thanks
Mike
