I'm only passing on what I have read somewhere, so this may be wrong.
The errors are deliberate and are part of the copy-protection scheme.
If you manage to skip the errors and write an error-free disc, the
playstation will reject it as a counterfeit.
So you'd have to copy the disc at a lower level. This makes sure that
only organised criminals can afford to make copies, not Johnny next door.
