100: // DETAILED DESCRIPTION OF ARGUMENTS
101: // fd: is the file descriptor provided by open()
102: // disknum is the disk number (0 to 127) in the RAID array
103: // command: defines the different operations.
104: // select: additional input data if needed (which log, which type of
105: // self-test).
106: // data: location to write output data, if needed (512 bytes).
107: // Note: not all commands use all arguments.
108: // RETURN VALUES
109: // -1 if the command failed
110: // 0 if the command succeeded,
111: // STATUS_CHECK routine:
112: // -1 if the command failed
113: // 0 if the command succeeded and disk SMART status is "OK"
