CreateTapePartition function

The CreateTapePartition function reformats a tape.

Syntax


DWORD CreateTapePartition(
  _In_ HANDLE hDevice,
  _In_ DWORD  dwPartitionMethod,
  _In_ DWORD  dwCount,
  _In_ DWORD  dwSize
);

Parameters

hDevice [in]

Handle to the device where the new partition is to be created. This handle is created by using the CreateFile function.

dwPartitionMethod [in]

Type of partition to create. To determine what type of partitions your device supports, see the documentation for your hardware. This parameter can have one of the following values.

ValueMeaning
TAPE_FIXED_PARTITIONS
0L

Partitions the tape based on the device's default definition of partitions. The dwCount and dwSize parameters are ignored.

TAPE_INITIATOR_PARTITIONS
2L

Partitions the tape into the number and size of partitions specified by dwCount and dwSize, respectively, except for the last partition. The size of the last partition is the remainder of the tape.

TAPE_SELECT_PARTITIONS
1L

Partitions the tape into the number of partitions specified by dwCount. The dwSize parameter is ignored. The size of the partitions is determined by the device's default partition size. For more specific information, see the documentation for your tape device.

 

dwCount [in]

Number of partitions to create. The GetTapeParameters function provides the maximum number of partitions a tape can support.

dwSize [in]

Size of each partition, in megabytes. This value is ignored if the dwPartitionMethod parameter is TAPE_SELECT_PARTITIONS.
