Members

ECC
Specifies whether the device supports hardware error correction. This member is TRUE if hardware error correction is supported.
Compression
Specifies whether hardware data compression is enabled or disabled. This member is TRUE if hardware data compression is enabled.
DataPadding
Specifies whether data padding is enabled or disabled. Data padding keeps the tape streaming at a constant speed. This member is TRUE if data padding is enabled.
ReportSetmarks
Specifies whether setmark reporting is enabled or disabled. This member is TRUE if setmark reporting is enabled.
DefaultBlockSize
Specifies the device’s default fixed block size.
MaximumBlockSize
Specifies the device’s maximum block size.
MinimumBlockSize
Specifies the device’s minimum block size.
MaximumPartitionCount
Specifies the maximum number of partitions that can be created on the device.
FeaturesLow
Specifies the low-order 32 bits of the device features flag. This member can be one or more of following values:

Value

Meaning

TAPE_DRIVE_COMPRESSION

The device supports hardware data compression.

TAPE_DRIVE_ECC

The device supports hardware error correction.

TAPE_DRIVE_EJECT_MEDIA

The device physically ejects the tape on a software eject.

TAPE_DRIVE_ERASE_BOP_ONLY

The device performs the erase operation from the beginning-of-partition marker only.

TAPE_DRIVE_ERASE_LONG

The device performs a long erase operation.

TAPE_DRIVE_ERASE_IMMEDIATE

The device performs an immediate erase operation ¾ that is, it returns when the erase operation begins.

The device performs a short erase operation.

TAPE_DRIVE_FIXED

The device creates fixed data partitions.

TAPE_DRIVE_FIXED_BLOCK

The device supports fixed-length block mode.

TAPE_DRIVE_INITIATOR

The device creates initiator-defined partitions.

TAPE_DRIVE_PADDING

The device supports data padding.

TAPE_DRIVE_GET_ABSOLUTE_BLK

The device provides the current device-specific block address.

TAPE_DRIVE_GET_LOGICAL_BLK

The device provides the current logical block address (and logical tape partition).

TAPE_DRIVE_REPORT_SMKS

The device supports setmark reporting.

TAPE_DRIVE_SELECT

The device creates select data partitions.

TAPE_DRIVE_VARIABLE_BLOCK

The device supports variable-length block mode.

TAPE_DRIVE_WRITE_PROTECT

The device returns an error if the tape is write-enabled or write-protected.

FeaturesHigh
Contains the high-order 32 bits of the device features flag. This member can be one or more of the following values:

Value

Meaning

TAPE_DRIVE_ABS_BLK_IMMED

The device moves the tape to a device-specific block address and returns as soon as the move begins.

TAPE_DRIVE_ABSOLUTE_BLK

The device moves the tape to a device specific block address.

TAPE_DRIVE_END_OF_DATA

The device moves the tape to the end-of-data marker in a partition.

TAPE_DRIVE_FILEMARKS

The device moves the tape forward (or backward) a specified number of filemarks.

TAPE_DRIVE_LOAD_UNLOAD

The device enables and disables the device for further operations.

TAPE_DRIVE_LOAD_UNLD_IMMED

The device supports immediate load and unload operations.

TAPE_DRIVE_LOCK_UNLOCK

The device enables and disables the tape ejection mechanism.

TAPE_DRIVE_LOCK_UNLK_IMMED

The device supports immediate lock and unlock operations.

TAPE_DRIVE_LOG_BLK_IMMED

The device moves the tape to a logical block address in a partition and returns as soon as the move begins.

TAPE_DRIVE_LOGICAL_BLK

The device moves the tape to a logical block address in a partition.

TAPE_DRIVE_RELATIVE_BLKS

The device moves the tape forward (or backward) a specified number of blocks.

TAPE_DRIVE_REVERSE_POSITION

The device moves the tape backward over blocks, filemarks, or setmarks.

TAPE_DRIVE_REWIND_IMMEDIATE

The device supports immediate rewind operation.

TAPE_DRIVE_SEQUENTIAL_FMKS

The device moves the tape forward (or backward) to the first occurrence of a specified number of consecutive filemarks.

TAPE_DRIVE_SEQUENTIAL_SMKS

The device moves the tape forward (or backward) to the first occurrence of a specified number of consecutive setmarks.

TAPE_DRIVE_SET_BLOCK_SIZE

The device supports setting the size of a fixed-length logical block or setting the variable-length block mode.

TAPE_DRIVE_SET_COMPRESSION

The device enables and disables hardware data compression.

TAPE_DRIVE_SET_ECC

The device enables and disables hardware error correction.

TAPE_DRIVE_SET_PADDING

The device enables and disables data padding.

TAPE_DRIVE_SET_REPORT_SMKS

The device enables and disables the reporting of setmarks.
