bad cd how to recover files ?

[humbleboy]

Hello all
Recently I burned 2 home movies on a Samsung DVD-r at 1x speed and now I am having trouble playing it on my standalone DVD. I tried to do a backup but still can not read from disk, it copies two. vobs and remaining another three files i got error "error performing inpage operation" and "data error (cyclic redundancy check)
I check cd on many other DVD players but no way it would work.
Anyone can please help how to recover my files?
Thank you

You can try DVDDecrypter and see if it can recover the files. It has a mode for a file with errors. The problem is, if the data is missing, it's missing. Not really recoverable. Sounds like bad media.

It may be you can only recover parts of the bad files. Then you would cut them out and work with what's left.

EDIT: Another program that I haven't tried for this purpose is ISObuster. Says it can extract corrupted files from a DVD.

I found out that i have two vob files have a damaged structure is there anyway to repair the structure ?

u can also try to make an image with acl 120 sometimes you can set the setting to "bad sector" or "bad media or something like that. basically it will try to make the image even with bad sectors

From what I have heard, ISObuster will extract from a scratched disc but from my experience, ISObuster or any other program will not recover the data from bad media (ritek/ridata). I ended up having to throw all 30 DVDs that I burned in the trash can.

It was God's way of telling me not to make copies of my brother's DVDs but to buy my own and to use good media when I do burn my back-ups. Not junk media that I can get for 50 cents a disc.

How did you find this out, were you able to get the files onto your hard drive? If so, any authoring program should be able to reauthor those VOBs to a new DVD.

If this is a home movie it is best if you can get the original, the errors you are getting means data is corrupted either in burn or was a bad media. You have to piece this together and you would have data loss. If dvdshrink reads it you can by pass the bad part in dvd rebuild option or do it in two parts and join it.

I an not able to copy to 4th and fth vob files to my hard disk i only copied 1,2 and 3rd files only. dvddycrypter syas bad sector but unable to recover,
so i pulled out the original dvd (because i always keep original dvd of all my home movies) and exactly the same error, can not copy files to my hard disk, so i am convinced that the dvd structure is damaged and that it is not scratched however i still i cannot copy to HD to re-author.
any ideas?

Well, according to the media list, there are only two types of Samsung discs that will burn at 1x.

BeAll G00001 which plays on 3 players but doesn't play on 4 players. Burn reliability is mixed and DVD reliability is poor.

Ritek G03, which a few people in here will stand up and praise as a great quality media and the only media that they use but the rest of us will tell you it's the worst media you can buy.

I sincerily hope that you have the original video tapes that these back-ups were made from because what you have is junk DVDs. I have been trying for months to figure out how to get the data off of 30 DVDs that I burned to Ritek/Ridata discs and have the exact same success rate that I had burning a readable DVD, Zero.

I did download a trial demo of Bad Copy Pro yesterday but without having save capablities in the demo, I have no idea if it is working or not and I'm not going to buy the program to find out. It took 2 hours to get 20% and I shut it down. Didn't make any sense to run it for 8 more hours when I wouldn't be able to see the files anyway. You may want to try it though, it's $50.
I also installed the new version of ISObuster to see if it had the capability to extract the whole DVD and it killed my old version which I could use on good DVDs and the only way that I can use it now is if I pay for it to make it work.

All I can tell ya is next time you want to put your home movies on DVD, buy quality media to put them on.

If your original is corrupted is bad burn or data on disc there is no way you can read bad data. make sure disc is absolutely clean, use decryptor try to read one file at a time on every dvd burner or rom you have see if it can be read. If not let it read it up to location it can and use editor to piece together. if original plays on dvd player capture via analog it's better than nothing then piece together

Not sure what program you are using to copy the data but every program that I have used either gets to the corrupted part and quits and gives you no data, runs for hours and quits and gives you no data or will give you data up to the first corrupted part of the DVD and no more (with bad media, there are corrupted parts throughout the whole DVD) getting enough of the movie to piece together would be impossible.

The capturing through a video card is an option that I had not thought of. Some of my DVDs played most of the way through with a skip here and there but it would be very time comsuming trying to capture all 30 DVDs to figure out which ones would work or not. Editing out the messed up scenes and blending the transitions together and re-encoding. The original posters video may be so important to him that he has no choice but to use this method or to pay a data recover service to try and recover the data..
