How to Rip a DVD |
|
CD/DVD copy protection is a blanket term for various methods of
copy protection for
CDs and DVDs.
Such methods include
DRM, CD-checks, Dummy Files, illegal tables of contents, over-sizing or
over-burning the CD, physical errors, and bad sectors. Many protection schemes
rely on breaking compliance with CD and DVD standards, leading to playback
problems on some devices. Protection schemes rely on distinctive features
that
- can be applied to a medium during the manufacturing process, so that a
protected medium is distinguishable from an unprotected one.
- can not be faked, copied or retroactively applied to an unprotected
medium using typical hardware and software.
Filesystems / Dummy files
Most CD-ROMs use the
ISO9660
filesystem to organize the available storage space for use by a computer or
player. This has the effect of establishing directories (ie, folders) and files
within those directories. Usually, the filesystem is modified to use extensions
indended to compensate for limitations in the ISO9660 filesystem design. These
include
Joliet,
RockRidge, and
El Torito extensions. These are, however, additions to the underlying
ISO9660 structure, not complete replacements. The most basic approach for a
distinctive feature is to purposely fake some information within the
filesystem. Early generation of software copied every single file one by one
from the original medium and re-created a new filesystem on the target medium. |
