+// DETAILED DESCRIPTION OF ARGUMENTS
+// fd: is the file descriptor provided by open()
+// disknum is the disk number (0 to 15) in the RAID array
+// command: defines the different operations.
+// select: additional input data if needed (which log, which type of
+// self-test).
+// data: location to write output data, if needed (512 bytes).
+// Note: not all commands use all arguments.
+// RETURN VALUES
+// -1 if the command failed
+// 0 if the command succeeded,
+// STATUS_CHECK routine:
+// -1 if the command failed
+// 0 if the command succeeded and disk SMART status is "OK"
