More bad sectors in the burned copy than in the original

I noticed that when I burn an image with bad sectors, e.g. SD protected, the burned copy has more bad sectors than the
original. Specifically, for each bad sector in the image the subsequent sector is also bad in the burned copy.
For example, if the sectors 809, 814, 819 are corrupt in the original, then sectors 809,810,814,815,819,820 are bad in
the burned copy.

I am using a LiteOn 24102B, and tried different software; CloneCD, CDRWIN, FireBurner. All with the same result.
This means that a copy has twice as many bad sectors as are in the original.

Can anyone explain why this is?

If this is a univeral thing, and the nature of the beast, then one would think that this would be a good way of checking to
distinguish a copy from the original. Just check the sectors following the bad sectors on the original.
Why don’t the copy protections like SD check for this?

Ssshhhhh… !!! dont ever give such ideas to the safedisc people. we have enough problems from them already. :bigsmile:
