Is my DVD-RW ruined?

I may try that some other time. I was just hoping someone could speak from experience doing the same thing.

Here is a picture of the smudge in question.

That's not a burn mark, but a manufacturing flaw!

By the way, CD's/DVD's burn from the inside out, so just limit yourself to 3 .5 GB and you will miss that mark entirely.

That mark never showed up until I had did that partial erase I mentioned above. I had used the disc before, but never did what I did above. When I erase them I always do the full erase and when done I check the back. Are you saying that I should have been able to do the partial erase and no mark should have been left behind?

Now that I have my external enclosure, it won't be hard to stay below 3.5 GB.

I doubt I will even use the discs anymore. I was just curious if I ruined my disc. The external enclosure is just so much easier and faster.

Exactly - the defect didn't show up until it was hit with a small amount of heat. That is why you didn't notice it before. It is a manufacturing flaw. Looks like the thin film is separating from the plastic backing.

A little CD trivia - the top side of a CD is much more vulnerable to irreparable damage than the bottom side that the laser shines through. Most people don't know that. The plastic on the top is much thinner.

Where did this CD get stored, Possiably could have got heat Warped.:hmm:

I keep them in my desk. It definitely didn't get heat warped in my desk. I keep very old CD-RWs in there and they haven't been affected. Actually they are at the bottom of the pile (each disc has its own case).
