IDiscFormat2Data::get_CurrentWriteSpeed method (imapi2.h)
Retrieves the drive's current write speed.
Syntax
HRESULT get_CurrentWriteSpeed(
[out] LONG *value
);
Parameters
[out] value
The write speed of the current media, measured in sectors per second.
Return value
S_OK is returned on success, but other success codes may be returned as a result of implementation. The following error codes are commonly returned on operation failure, but do not represent the only possible error values:
| Return code | Description |
|---|---|
|
The request requires a current disc recorder to be selected.

|
Failed to allocate the required memory.
Value: 0x8007000E |
|
The device failed to accept the command within the timeout period. This may be caused by the device having entered an inconsistent state, or the timeout value for the command may need to be increased.
Value: 0xC0AA020D |
|
The device reported unexpected or invalid data for a command.
Value: 0xC0AA02FF |
|
The media is inserted upside down.
Value: 0xC0AA0204 |

The drive reported that it is performing a long-running operation, such as finishing a write. The drive may be unusable for a long period of time.
Value: 0xC0AA0207 |
|
The write failed because the drive did not receive data quickly enough to continue writing. Moving the source data to the local computer, reducing the write speed, or enabling a "buffer underrun free" setting may resolve this issue.
Value: 0xC0AA0300 |
|
The media is not compatible or of unknown physical format.
Value: 0xC0AA0203 |
|
The DVD structure is not present. This may be caused by incompatible drive/medium used.

The drive reported that the combination of parameters provided in the mode page for a MODE SELECT command were not supported.
Value: 0xC0AA0208 |
|
The drive reported that the media is write protected.
Value: 0xC0AA0209 |
|
The media's speed is incompatible with the device. This may be caused by using higher or lower speed media than the range of speeds supported by the device.
Value: 0xC0AA020F |
|
The specified handle is invalid.
Value: 6 |

Value: 0xC0AA0301 |
Remarks
To retrieve the requested write speed, call the IDiscFormat2Data::get_RequestedWriteSpeed method.
To retrieve a list of the write speeds that the recorder and current media supports, call the IDiscFormat2Data::get_SupportedWriteSpeeds method.
Note that the write speed is based on the media write speeds. The value of this property can change when a media change occurs.
