Bad Sectors...why?

[Sepu]

So...what's true behind BAD SECTORS?? where is the problem with these DVDs that don't work for someone..and work for someone other.
It's just the player?

I've some DVDs that anyway are "Empty" for 1 player, and are "true" for another...
There is a way to deal with bad sectors? to copy anyway a DVD?

My opinnion, do way should bad sectors be spreaded anymore. If you find, cut it off from the circle. The other DVD-Burners read the media differently. Other Burners can't write the media perfectly. There isn't a burner that can burn all the blank media 100%. They are only fit to some of these blank discs. Let it be known that for instance, NEC burners aren't the best ones to read media. One little scratch on the surface of the discs and it says you can't read it. Now take that disc to let say Lite-On burner and it reads it perfectly.

So to summ it up, it's the player with the help of a not suitable media for that player which it was burner.

I have two NEC burners and I've never had any problems with them. In my experience, they read DVDs better than Sony and Creative. I've never used LiteOn though.

About bad sectors.....if there is a true bad sector on a DVD disc, then no burner can read it (no matter how good it is).

However, most bad sector errors are caused by a disc that's either scratched or dirty. Most of the time, if I clean a disc with isopropyl alcohol then the disc can be read fine.

I've also noticed that cheap media are much more prone to developing bad sectors.

I noticed that too...it's better to spend money for good quality DVDs only.

About NEC, by burner is NEC, and there is a DVD that see "empty".
My other player can see it without problems. About burning, NEC works fine for me.

Pioneer 108 here, love it reads all, had 3dvds it didint read (from 1 trader but he had burning issues)

I too have two NEC burners and they won't read if you have a scratch on it. Perhaps it's too deep to read.

Just to make an example again about this damn problem:

I usually don't make verify after the burning with Nero.
This time, I tried to verify 1 disc, and rip it (I've 2 different DVD players)

1st rip:
VOB3/VOB4 have bad sectors, so I tried to rip them with the 2nd player, it worked fine!

2nd rip:
I tried to rip it all with the 2nd player, I got bad sectors too on other VOBs!!

So, the only way it worked, was to rip some VOBs with player1 and some others with player2.

That's it's really impossible to understand for me:wacko:
It's always bad finally when u got or you send out stuff with bad sectors.

So you're saying you got some bad sectors on the first burn and some other bad sectors on the second burn? Because the bac sectors that you found would most likely have to do with the burn you made, not the rip. Are you running any other processes while burning? And do you have a good burner/blank media?

[Sepu]

No, the same burned DVD that I tried to rip in 2 different way...

Hardware: NEC DVD burner and Verbatim DVD+R 16x.
Maybe I found the difference.

I tried to burn/verify a DVD burned at 16x, during the verify, at 94%, I got an error and I had to crash 3 different DVDs (I tried 3x)

So, I tried to burn/verify the same thing at 8x, no errors!!
Probably 16x it's really too much....

Well with my old burner (that was only 1-4X) I would got a lot more errors when burning at 4X versus 2X or 1X, but with my new Samsung burner, I've burned 25+ DVDs all on 16X and no trouble!
