Method and apparatus for storing and retrieving copy-protected data within
storage devices such as, for example, disc drives. Data that is to be
copy protected is written on the storage device. A first data list, such
as a manufacturer's storage device defect list, is copied and used to
make a second data list. Then, the first data list is modified such that
the area where the copy protected data is stored is identified as
defective. Unless a request to read the copy protected data is received,
the first data list is used and the copy protected data area is
considered defective. However, if a request to read the copy protected
data is received, the second data list is used and the copy protected
data is read from its storage location.
