Module Name:

|
|
|
drive.hxx
|
|
|
|
Abstract:
|
|
|
|
The drive class hierarchy models the concept of a drive in various
|
|
stages. It looks like this:
|
|
|
|
DRIVE
|
|
DP_DRIVE
|
|
IO_DP_DRIVE
|
|
LOG_IO_DP_DRIVE
|
|
PHYS_IO_DP_DRIVE
|
|
|
|
DRIVE
|
|
-----
|
|
|
|
DRIVE implements a container for the drive path which is recognizable
|
|
by the file system. 'Initialize' takes the path as an argument so
|
|
that it can be later queried with 'GetNtDriveName'.
|
|
|
|
|
|
DP_DRIVE
|
|
--------
|
|
|
|
DP_DRIVE (Drive Parameters) implements queries for the geometry of the
|
|
drive. 'Initiliaze' queries the information from the drive. What
|
|
is returned is the default drive geometry for the drive. The user
|
|
may ask by means of 'IsSupported' if the physical device will support
|
|
another MEDIA_TYPE.
|
|
|
|
A protected member function called 'SetMediaType' allows the a derived
|
|
class to set the MEDIA_TYPE to another media type which is supported
|
|
by the device. This method is protected because only a low-level
|
|
format will actually change the media type.
|
|
|
|
|
|
IO_DP_DRIVE
|
|
-----------
|
|
|
|
IO_DP_DRIVE implements the reading and writing of sectors as well
|
|
as 'Lock', 'Unlock', and 'Dismount'. The 'FormatVerifyFloppy' method
|
|
does a low-level format. A version of this method allows the user
|
|
to specify a new MEDIA_TYPE for the media.
|
|
|
|
|
|
LOG_IO_DP_DRIVE and PHYS_IO_DP_DRIVE
|
|
------------------------------------
|
|
|
|
LOG_IO_DP_DRIVE models logical drive. PHYS_IO_DP_DRIVE models a
|
|
physical drive. Currently both implementations just initialize
|
|
an IO_DP_DRIVE. The difference is in the drive path specified.
|
|
Some drive paths are to logical drives and others are to physical
|
|
drives.
