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.
