DVD-R & CD-R Verification

Hello,

I was wondering if there are any utilities out there that will verify a CD or DVD after it has been burned. I am running Roxio Easy CD Creator and it doesn't have this feature. I read somewhere that there is a small utility (check disc or disc scan), which compares your burned media to the original files. I can't seem to find out about it through this site, Google or dvdhelp. I need this feature for a DVD data backup.

Thanks,
Rob

I am using roxio for dvd data back-up and did not had any problems(so far).
You could open 2 windows and compare the file size, but that could be too much work-I guess.My xp os is back-up on dvd and had to restore one time-nasty virus.My back-up files worked fine.I trust roxio.

The point of this is not the software really but rather the media.
I'd imagine most of the burning software does a read after write check. I've had my Sony drive report write errors via DVDA so that part of the equation works.

What is more interesting is knowing the amount of error correction required to read the data back. If you're really serious about quality product this would seem to be a vital bit of info. After all if the DVD is within one bit more of error before a sector becomes unrecoverable I don't think you'd want to be keeping that as a master copy.

One option is CDCheck at:

Thanks.

I'll try it out. The reason this item came up was that I have 6 VHS-C tapes that I converted through my camcorder and wanted to archive the AVI files to DVD. Through an Internet search I found out that Nero includes a verify option after the disc has been burned. I don't know why this option isn't included in Easy CD Creator Platinum. I might just have to switch to Nero.

Certainly Nero can do a read after write check. But the check is applied after error correction. Just because your data is OK today doesn't mean it'll be OK tomorrow.
