A big problem stemming from the music industry’s attempt to regulate music file sharing is the introduction of copy-protected cds into the market. The purpose of the copy-protection is to prevent digital copying of the files fromlegally purchased cds(not even backups). However, in those attempts they often keep people from even listening to the cds on computer or in car cd players and sometimes the copy-protection even causes damage. Fat Chuck’s – Corrupt CDs contains, among other information, a list of cds known to have copy-protection on them which can be helpful for diagnosis if one of your computers suddenly stops working for no reason.
