ISO buster question

[DVD_NDN]

g'day all.
so heres the situ.
I have a DVD that, despite not seeing any scratches on it - keeps getting the same result 'cyclic redundancy error'. I am (at this very moment) using iso buster to try and get around the 'scratched' areas, inserting dummy data.

the thing is, this is my first time using iso buster, and, well, the program has been going at it for almost 12 hours now. it IS making progress, at an incredibly slow pace. so, I've convinced myself now, that I dont know what I'm doing, and may have blown a day trying to get this dvd backed up.

can anyone tell me what the process is using iso buster to repair, or retrieve data off the disc so that it can be stored onto the hard drive, and well the rest I can do - its just that damned 'cyclic redundancy error' .. 12 hours for a scratch thats not... well, is PROBABLY not even there?
anyone feel like handing me a clue?

Hi DVD_NDN

I guess my lead question is what exactly are you trying to do with that DVD? If it's a backup you're after, try a DVD decryptor tool to extract the contents of the DVD to your hard drive. Once you've doe that you can create an ISO image of it using most popular burning software apps, like Nero.

Please let us know so we can assist you better, ok?

Cheers!

hey;

ok so, yeah I WAS trying to back up a dvd before it became scratched ("scratched"). unfortunately, I let it lag, and other projects took over... thought 'yeah it'll be there...' well, when the time came, and I finally got around to it, the dvd I was trying to back up (additional note - bought it at a hock shop... all sales final) gave me an error in the very program you mentioned, and we all love - dvd decrypter.
the error read as 'cyclic redundancy error'.

ok, well its been my understanding that an error that reads such as that is usually indicitive of a scratch or some form of imperfection on the disc. I I took a closer look at it than when I purchased it, and go figure - not a mark.

So, thinking maybe my eyes have decieved me, or that on the offchance that an imperfection was present yet not visible to the naked eye, I placed the DVD into my repair/cleaning machine (wal-mart special), and I did both a cleaning, then repair, in that order.

expecting a triumphant vicotry, and looking foreward to the moment when I place the dvd into my drive and see it work, instead I find the program giving me a big fat middle finger - "cyclic redundacy error".

baffled, and now somewhat frustrated, I download the program which I understand to be one of the better programs in order to retrieve data from a damaged disc - ISO buster.

I read the help file which was with the program, and followed the directives. once again sensing that my victiry was near, I allowed the program to 'do its thing', and after what amounted to work in the neighborhood of 13 hours, I was met once more with the evil DVD laughing at me. taunting me 'cyclic redundancy error'.

The DVD met its end at that point. upon waking and finding that it was unsuccessful I decided that the DVD was an ugly duckling of sorts. that it had found itself incarnated as a DVD, but in fact was a frisbee.

I'm sure at least one of my neighbors now believes that we have been visited by beings from another planet as I heard them talking about this disc flying overhead.... keep an eye out for news of a UFO in northern ontario, and if I am right about the guy - possibly an exxagerated account of being abducted and probed...

but I digress...

yes, I wanted to back up my movie, but... it didnt work. I am on a mission today to buy it again, this time brand new.

my narrative noted above not withstanding, I am still very much curious about the process which may have taken place to lead to said results.
I'm sure it COULD be a wide variety of issues. I'm interested in hearing any and all.
it bothers me to no end that I could not get around that little problem.
please also note that the dvd did play fine in my standalone dvd player without any issue whatsoever. no artifacts, or pixelization, nothing.
adding more to my frustration.

Just to be devils advocate, but still wishing to help!

have you tried cleaning the laser lense?
have you tried ripping in a different drive? (if you ahve one)

as recommended above, could be worth trying other ripping programs.

does the drive you are using, sucessfully rip other discs?

??

That was among the most entertaining posts I've read in a long time, DVD_NDN - I apologize if there was something unintentional in my post that brought that on, but thanks for the reply!!!

I know exacty where your frustration comes from, as I've ben in the same boat, save for the fact that the DVD I had purchased was not in production anymore and I wound up grabbing the same movie on VHS and capturing/rendering it to DVD manually. When all was said and done, I wish I had not given that disc to my boys, who hungrily set it afire in the microwave. . .

But I digress . . .

These CRC errors can arise from a multitude of issues - dirty lens, poor tracking, incongruent drive speed during the ripping, and minor surface imperfections on the DVD reflective side can all contribute to them. Media issues alone often account for the bulk of these CRC mismatches.

I wish you much better luck moving forward, and I hope you get to back-up your new copy sans problems, my friend!

Cheers!

hey, thanks guys, the quick replies are great!

zworg2:
I dont have another dvd writer, but it does successfully rip other dvd's, telling me that the problem is disc specific. I DO have a dvd lens cleaner for my standalone dvd player, but I havent tried putting that into the computer because I'm superstitious - actually, I just really dont know if it would be a good idea or not. I cant begin to fathom why my dvd lens cleaner disc wouldnt work on the computer, however, I'm of the belief that if It DOES happen to create an even bigger problem, I will have an aneurysm or some other overly dramatic incident.

TaoTeWingChun:
I aim to please. I am glad I at least brought you some entertainment (seriously, theres no sarcasm there). In my own opinion, I believe that bringing a smile or a chuckle to somebody is a pretty big thing. and I mean really, yeah I was pissed at that damned demon disc, but... I have to laugh at it (or else 'they' win).
additionally, cudos to the boys. I've always wondered how it would look to see a disc, or any metal in a microwave would look... I think its something like genetic memory from our ancestors - 'sharp or shiny mean good, make fire better'.
lol. must've been pissed.

I did pick up the new dvd. its not the same version, I guess it has some other features or something - the cover art/jacket is a little different, but... so long as the movie is more or less the same (I'm not an uber puritan bout it... very seldom I am), I'm happy.

of course, that been said - now I am shrinking a different movie, and the ghosts of the past haunt me, as once again this movie is being put on the back burner so to speak.
my luck this will all happen again. so, I'm just not taking the movie out of the shrinkwrap until I am fully prepared to coddle te damned thing.

thank you guys for the help. keep it coming if anything else comes to mind.

Hey DVD_DN, I just thought I'd share with you that most stand-alone players use the same drives that can be found on computer store shelves. When my beloved Apex 1200 died, I replaced the drive and was back in business in an hour (WooHoo!!!), so no problems using a les cleaner in your PC drive, I've done it a few times with no adverse reaction.

As for making fire better, I regret showing my boys that particular type of lightshow that dark winter night when we were snowed in and there was nothing good on the tele!!! But still, it puts a smile on their faces, so it can't be all bad, desite protestations and screaming by the Mrs, right?

Cheers!

i understand, but as above, it shouldnt be any problem at all, the actual inards of all DVD drives, be they PC, laptop standalone, playstation etc look the same and a lense cleaner will work as well in all of them.

of course, that been said - now I am shrinking a different movie, and the ghosts of the past haunt me, as once again this movie is being put on the back burner so to speak.

NOW.....DO IT NOW MAN...DO IT

8) :P

Rip it and back it up whilst you know it works!!!!!!

:P
