LogicalSize integer This parameter is not used for InitializeAction.
InitializeAction always formats to PhysicalSize, regardless of what is
specified in LogicalSize. A query returns the current size (in pages) of the
file system on the device.
A value of 0 (zero) indicates that the device is not mounted.
Legal value: Any non-negative integer, including 0 (zero).
The value of LogicalSize must be less than or equal to the value of
PhysicalSize. A rangecheck error occurs if you try to set a larger value or
set the value to 0 (zero).
Mounted boolean True System attempts to mount the flash.
False System attempts to dismount the flash.
When a device is mounted, it becomes known to the system and is
readable, depending on the nature of the device.
A device must contain a valid file system or it will not mount successfully. To
verify if the device is currently mounted, query this parameter immediately
after setting it.
PhysicalSize integer (Read-only) Indicates the size of the flash (in pages) for a flash that is
mounted. A value of 0 indicates that the device is not mounted.
Removable boolean (Read-only) Indicates if the drive supports removable flash.
Searchable boolean (Read-only) Indicates if the flash participates in searches in file system
operations that specify a filename without specifying a device.
SearchOrder integer (Read-only) If the Searchable parameter is True, indicates the priority at
which the flash is searched for a file in operations where no device has
been specified. A lower integer indicates a high priority. If the Searchable
parameter is False, the value of this integer has no meaning.
Type name (Read-only) This constant always returns the value of /FileSystem.
Writeable boolean (Read-only) Indicates if the files on the flash can be opened for write
access. A write-protected flash returns False. When the flash is not
mounted, this parameter indicates if the device supports writeable media.
Device Parameters for the IODevice %rom%
BlockSize integer (Read-only)
Free integer (Read-only) Indicates the amount (in pages) of free space available in
ROM. Valid only if the ROM is mounted (mounted is set to True). A value of
0 (zero) indicates that either the ROM is not mounted or it is full.
HasNames boolean (Read-only) Indicates if ROM supports named files. Valid only if ROM is
mounted (mounted is set to True). If ROM is not mounted, this parameter
has a value of False.
InitializeAction integer (Read-only) Always returns a value of 0 (zero), which indicates no action.
