3.52 SYNCHRONIZE CACHE (16) command
The SYNCHRONIZE CACHE (16) command (see table 201) requests that the device server ensure that the specified logical blocks
have their most recent data values recorded in non-volatile cache and/or on the medium. Logical blocks include user data and, if
the medium is formatted with protection information enabled, protection information. Logical blocks may or may not be
removed from volatile cache and non-volatile cache as a result of the synchronize cache operation.
See the SYNCHRONIZE CACHE (10) command (see 3.51) for the definitions of the fields in this command.
