BAD SECTORS on Audio CDs

[domenicaccio]

I have experienced a weird problem with the simple task of duplicating an Audio CD:

- some CDs cause burning SW to detect BAD SECTORS: the SW
just gets stuck or skips the rest of the song or writes "gaps"
(perfectly hearable) on the CD image -> problem is in READING
- the BAD SECTORS are usually from 10 to 50, and always in
the last song (I assume that Audio CD are NOT protected,
anyway)
- the original CD sounds PERFECT both on home Audio CD Players
and on the very simple Windows CD Player, without any "gap"
- the following burning SW was tried (and failed): Adaptec EasyCD
Creator, Nero Burning Rom, CDRWin, BlindRead
- the same problem is with other-purpose extracting SW, such
as AudioCatalyst, YAMP and Mp3TOOLZ

Please anyone who is experienced in Audio CD Burning give a
hint! I am disappointed by the fact that I can HEAR the CDs
well but I cannot make a correct IMAGE on the hard disk.

Thanx, Domenicaccio
