I have been making .mpgs of my daughter for the past two years. Today I tried to copy them from the DVD+R disks that I copied the .mpgs to for safe keeping and Windows will display the files on the disk, but when I try to play or copy, Windows fails with "cyclical redundancy check" error.
I COULD CRY!!!!!! I have lost the first two years of my daughter videos if I can't retrieve these.
Is there anyway possible to be able to pull these files off the discs, or am I screwed?

+what state are the discs in.The error you are providing is one that details crappy media, dirty or scratched discs.
If your pc still sees the files but you cant view them, try this 1st.
1.1right click the disc when its in the drive and try to copy and paste the files across.
if this fails my other suggestion is for you to try using isobuster the files recovery application.
heres a link:
software description:
Rescue lost files from a bad or trashed CD or DVD !
Save important documents, precious pictures or video from the family, your only system backup, ...
IsoBuster can do it all !
IsoBuster is a highly specialized yet easy to use CD and DVD data recovery tool. It supports all CD and DVD formats and all common CD and DVD file-systems (= set of files and folders). Start up IsoBuster, Insert a CD or DVD, select the drive (if not selected already) and let IsoBuster mount the media. IsoBuster immediately shows you all the tracks and sessions located on the media, combined with all file-systems that are present. This way you get easy access, just like explorer, to all the files and folders per file-system. Instead of being limited to one file-system that the OS picks for you, you have access to "the complete picture". Access data from older sessions, access data that your OS (e.g. Windows) does not see or hides from you etc.
Combine this all-revealing functionality with far better read and recovery mechanisms, scanning for lost files functionality, workarounds for a wide range of drive and software bugs, limitations or shortcomings and you have an enormously powerful data recovery tool. IsoBuster is must-have-software for every PC user and is deliberately kept low priced to be able to offer a solution for everybody, even if it is much used in the professional optical and data forensics world.

The discs are mint...not a scratch or finger print. I have been using iso buster 1.8 and CDCheck 1.9 for the past three days now and I was able to recover one disc, but the others are giving problems. I have two computers, so I'm running both tools to see which will work. ISO buster ran for 2 days on one disc and eventually got hung. I will take the discs to work (Hewlett-Packard) and try on some new systems.
I will also try to locate the 8X drive I used to burn the discs to try to read them. I'm using a 16X drive right now and it may have trouble reading discs made with another drive. Luckily I'm a project manager with the removable storage group, so I have access to any optical drive I need.
If all else fails, I'll have to re-make every video from the master mini-DVD tapes. I figure it would take me about two weeks to re-build them all.
I guess that will teach me to rely on DVD media as my sole backup.

dvd media does have its problems, i read an article by scubapete about the longlife of these products not being 100 years as expected but having a shorter life span of say 5 years.
Tests are being carried out currently to see if they can prolong it further but my advice to you is to keep re backing up the stuff you really want to keep evry 3 or so years and always use good media.
Sorry you didnt get the out come you expected.

Maybe you could also try something like restorer2000.
I know its designed to retrieve data from corrupt or formatted HDD's but it may be able to cope where the standard programs can't.
I think the trial version will let you rescue items up to 64k in size, at least this will either prove its worth or save you buying it.
There are other programs out there, some may be free, but its what I use and it works every time I've tried it on otherwise lost data on drives.

Well luck was on my side today. I went to work and grabbed a Philips 8X DVD+/-RW drive (which I suspect is the same model drive I used to create the DVDs) and I was able to read and copy my data using this drive. I did have to use ISOBuster 1.8 on 1 of the five disks, but nonetheless I got all my videos back. Yeah!
I restored all the data to a third hard drive and I'll look into using multiple drives when I setup my new 3.6GHz system (with SATA drives). I'll also get a Maxtor 1-touch external HDD for more data storage.
I will never rely on DVD's again. If I do copy to a DVD, I'll triple check that the data is readable on multiple drives.

madforce, it has been my experience that when all else fails, read the disk to your HD with a computer DVD player drive. Not a burner, just a plain old DVD player drive like they had before burners came out.
Don't ask me why or how, but those old drives will read disks that look totally trashed, and they blow through "cyclical redundancy" errors like they were not even there. Sometimes SIMPLE is better!

it's been MY experience that the burner that you wrote the disk with is the best way to read a problem disk! and I often use the same drive to read and write and I have 2 DVD drives in my computer! Do what works for you...... and I'm glad that madforce finally had success! here is a good link on Longevity of DVDs: http://www.videointerchange.com/dvd.htm#DVD
scroll down to the longevity section..... very good read on handling the disks..... but if you do get a cycle redundancy error.... it may not be a scratched disk at all... it's just that the drive isn't reading it! It's spitting it out.... try booktyping your writer to DVD-ROMs so you disk can be more acceptable to most DVD players! You can do this to only DVD+Rs....good luck!

Can anyone helps with this -
I am getting a cyclical redundancy check error message when copying large files from my mp3 player to my hard drive. This seems to be because I accidentally compressed the data on my mp3 hard drive or similar. The files play fine on my mp3 player but I can not move them ... is this similar or any suggestions?
Ta George

@talkgeorge....... welcome to AfterDawn........this question has been answered and now you're asking a totally different question pertaining to "cyclical redundancy check error" in a totally different format (not video but audio!). Try asking your question in the right forum like CD or Audio section..... you'll get more of a responce that in the middle of a thread that solved a different problem.......but........ a cyclical redundancy error is caused by bad media or the drive can't read the disk and thinks there's a dirty disk or scratched disk and therefore spits out THE CYCLICAL REDUNDANCY! I don't know enough about compressed audio files that play in your MP3 player and now you can't move them elswhere.....try asking your question in Audio section of the Forum. good luck. and sorry I can't help out.
