 From wikipedia:
All SD cards incorporate a digital rights management 
<http://en.wikipedia.org/wiki/Digital_rights_management> (DRM) scheme. 
Roughly 10% of the storage capacity of an SD card is not available to 
the user, but is used by the on-card processor to verify the identity of 
an application program 
<http://en.wikipedia.org/wiki/Application_program> that it will then 
allow to read protected content. The card prohibits other accesses, such 
as users trying to make copies of protected files.
