/* READ THIS!

* This class was created in an effort to reduce the complexity of the
|
|
* GParted_Core class.
|
|
* This class provides support for motherboard based RAID devices, also know
|
|
* as Fake RAID.
|
|
* Static elements are used in order to reduce the disk accesses required to
|
|
* load the data structures upon each initialization of the class.
