Mounted boolean True System attempts to mount the disk.
False System attempts to dismount the disk.
A device must contain a valid file system to mount successfully. When a
device is mounted, it is known to the system and is readable. To verify if the
device is currently mounted, query this parameter immediately after setting
it.
PhysicalSize integer (Read-only) Indicates the size of the disk (in pages). Valid only when the
disk is mounted. A value of 0 (zero) indicates that the device is not
mounted.
Removable boolean (Read-only) Indicates if the drive supports removable disks. Always returns
False.
Searchable boolean (Read-only) Indicates if the disk participates in searches in the file system
operations that specify a filename without specifying a device.
SearchOrder integer (Read-only) If the Searchable parameter is True, indicates the priority
assigned to the disk when searching for a file and no device has been
specified. A lower integer indicates a higher priority. If the Searchable
parameter is False, this value is ignored.
Type name (Read-only) Always returns the value of /FileSystem.
Writeable boolean (Read-only) Indicates if the files on the disk can be opened for write access.
If the disk is write protected, this parameter is a constant equal to False.
When the disk is not mounted, this parameter indicates if the drive supports
writeable media.
Device Parameters for the IODevice %flash1%
BlockSize integer (Read-only)
Free integer (Read-only) Indicates the amount of free space available (in pages) on the
flash. Valid if the flash is mounted (mounted is set to True). A value of 0
(zero) indicates that either the flash is not mounted or is full.
HasNames boolean (Read-only) Indicates if the flash parameter is only valid when flash is
mounted (mounted is set to True). If flash is not mounted, the parameter
has a value of False.
InitializeAction integer Specifies an action for initializing flash:
0 Indicates no action; the value returned when the parameter is read.
1 Indicates that the current file system should be deleted and a new
one of PhysicalSize created (the flash must be formatted already).
The flash must first be mounted; otherwise, an ioerror results.
2 Reformats the entire flash before creating a new file system of
PhysicalSize
3 (or greater) has the same effect as the value 2 and also tests the
flash x – 2 times
Legal value: Any non-negative integer.
