InitializeAction

integer

Specifies an action for initializing the disk. Supported values are:

0

Indicates no action; the value returned when the parameter is read.

1

Indicates that the current file system (if any) should be deleted and a new one
of

LogicalSize

created (the disk is assumed to have been formatted already).

The disk must first be mounted; otherwise, an

ioerror

results.

2

Reformats the entire disk before creating a new file system of size

LogicalSize

.

3

(or greater) has the same effect as the value 2 and also tests the disk x - 2
times.

Note:

The current file system refers to /FileSystem. See Type as follows for more

information.

LogicalSize

integer

Specifies the size of the file system to be created and is as an argument by InitializeAction.

• If 0 (zero), InitializeAction uses the size of the entire disk. When queried, indicates the

current size of the file system on the device (in pages). A value of 0 indicates that the
device is not mounted.

• If set with a certain value and the device is reformatted, a query returns the value that

was set. If queried before the disk is reformatted, a different value from the one set may
be returned because it may return the current size.

• If set to 1, 2, or 3, an

ioerror

occurs.

Legal value: Any non-negative integer, including 0. The value must be less than or equal to
the value of PhysicalSize. If set to a value greater than PhysicalSize, or less than zero, a

rangecheck

error occurs.

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.
