GetSupportedSize method of the MSFT_Partition class

Retrieves the minimum and maximum sizes that the partition can be resized to using the Resize method.

Syntax


UInt32 GetSupportedSize(
  [out] UInt64 SizeMin,
  [out] UInt64 SizeMax,
  [out] String ExtendedStatus
);

Parameters

SizeMin [out]

The minimum size that this partition can become, in bytes. If this method is run multiple times, this value can change slightly depending on the placement of various temporary files.

SizeMax [out]

The maximum partition size that this partition can become, in bytes.

ExtendedStatus [out]

A string that contains an embedded MSFT_StorageExtendedStatus object.

This parameter allows the storage provider to return extended (implementation-specific) error information.

Return value

Success (0)
Not Supported (1)
Unspecified Error (2)
Timeout (3)
Failed (4)
Invalid Parameter (5)
Size Not Supported (4097)

There are not enough resources to complete the operation. (40002)
Cannot shrink a partition containing a volume with errors. (42008)
Cannot resize a partition containing an unknown file system. (42009)

Remarks

The minimum size is determined by Disk Defragmenter and takes into account the location of immovable files (that is, files that cannot be moved). The maximum size is determined by adding the size of any free extents immediately after the current partition.
