Constants


`IMAPI_FORMAT2_DATA_MEDIA_STATE_UNKNOWN` Value: 0 Indicates that the interface does not know the media state.
`IMAPI_FORMAT2_DATA_MEDIA_STATE_INFORMATIONAL_MASK` Value: 0xf Reports information (but not errors) about the media state.
`IMAPI_FORMAT2_DATA_MEDIA_STATE_UNSUPPORTED_MASK` Value: 0xfc00 Reports an unsupported media state.
`IMAPI_FORMAT2_DATA_MEDIA_STATE_OVERWRITE_ONLY` Value: 0x1 Write operations can occur on used portions of the disc.
`IMAPI_FORMAT2_DATA_MEDIA_STATE_RANDOMLY_WRITABLE` Value: 0x1 Media is randomly writable. This indicates that a single session can be written to this disc. Note This value is deprecated and superseded by IMAPI_FORMAT2_DATA_MEDIA_STATE_OVERWRITE_ONLY.
`IMAPI_FORMAT2_DATA_MEDIA_STATE_BLANK` Value: 0x2 Media has never been used, or has been erased.
`IMAPI_FORMAT2_DATA_MEDIA_STATE_APPENDABLE` Value: 0x4 Media is appendable (supports multiple sessions).
`IMAPI_FORMAT2_DATA_MEDIA_STATE_FINAL_SESSION` Value: 0x8 Media can have only one additional session added to it, or the media does not support multiple sessions.
`IMAPI_FORMAT2_DATA_MEDIA_STATE_DAMAGED` Value: 0x400 Media is not usable by this interface. The media might require an erase or other recovery.
`IMAPI_FORMAT2_DATA_MEDIA_STATE_ERASE_REQUIRED` Value: 0x800 Media must be erased prior to use by this interface.
`IMAPI_FORMAT2_DATA_MEDIA_STATE_NON_EMPTY_SESSION` Value: 0x1000 Media has a partially written last session, which is not supported by this interface.
`IMAPI_FORMAT2_DATA_MEDIA_STATE_WRITE_PROTECTED` Value: 0x2000 Media or drive is write-protected.
`IMAPI_FORMAT2_DATA_MEDIA_STATE_FINALIZED` Value: 0x4000 Media cannot be written to (finalized).
`IMAPI_FORMAT2_DATA_MEDIA_STATE_UNSUPPORTED_MEDIA` Value: 0x8000 Media is not supported by this interface.

Remarks

This enumeration should be treated as a bitmask. Nearly all of the values set one bit set to one and the other bits to zero. Three exceptions to this rule were added: unknown, unsupported media mask, and informational mask. For example, to test for unsupported media, check the value against IMAPI_FORMAT2_DATA_MEDIA_STATE_UNSUPPORTED_MASK.

Requirements

Requirement	Value
Minimum supported client	Windows Vista, Windows XP with SP2 [desktop apps only]
