DVD-R Backups - do we need to bother verifying data anymore?

Seems most of us use DVD-R media for backups and for giving to our clients. Is there really a need to use the "verify data" feature anymore when burning? With the new speed of writers, it takes about 6 minutes to burn a DVD, then about 12 minutes to verify. Every time I use "verify data" I wonder if it's worth the time.

Does anyone have horror stories here, or can we actually trust a media?

I always varify. Just had one the other day with unreadable bad sectors. Very rare but worth the xtra time.

I always verify. It's not uncommon for me to come up with errors. Especially with the Super drive 8.5 disks, it seems.

Thanks - seems pretty unamimous still.

I've always done verification. I've done hundreds of DVD-R's for backups and I've burned a few coasters, but all DVD's that burned have verified successfully before - hence the original post. How very ironic. Well, tonight I experienced a successful burn and bad verification - good thing I did verification as the files were about to get deleted.

Thanks for keeping me in line!

Never trust the media, always verify!
The extra time it takes for verification is *nothing* compared to your client's frustration 3000 miles away who finds out that the copy does not work. The golden rule : make a backup (copy) and always verify. Without verification, your backup copy is useless.

Beyond using the verification function, best to actually open the file from the disk. And make two while you're at it.
