Making a backup from a backup.

It's all digital. If you do a burn and verify with no errors then you have a bit for bit copy. The backup becomes the original.

Kelson,


How do I verify to see if there are any errors? I use shrink and decryptor.

In Decrypter, when you select ISO-->Write, you should see three checkboxes, one of which is "Verify".

What if I already have burned them? Is there any other way to see if there are errors on the disc.

Extremely useful s/w, IMHO.

You can use something like DVDinfo or the analogous app that comes with Nero to scan the DVD and tell you if there are bad spots on the disk after the burn. But unless you have the original ISO that you made the burn from, you have no source image to do a data compare with. The Decrypter default is to verify after the burn. Unless you changed that, you probably did.


Anyway, why bother with this. They are just backups. If the cheap media gives you problems down the road you still have the original DVDs to make fresh copies from.

Is there anything wrong with the current backups? Are you experiencing 'fading'?

No. But I'm afraid the media will go bad down the road based on all the horror stories I hear about CMC media. I probably will just scrap the whole idea and wait and see if any of the cheap media goes bad in the future.
