MDL Command
The management area consists of the first three bytes. If the value written to
this area as the total number of overwrite operations is 100,000 (0186A0)
times or more, an end code warning of 76 will be returned.
The number of overwrite operations is written in hexadecimal code in the
management area. Data can be read from the management area using the
Read command. If the management area data is already 100,000 times or
more, the data in the management area will not be updated and only a warn-
ing will be returned as a response. If the updated number of overwrite opera-
tions is set to 00, the number will not be updated and only the number of
overwrite operations can be checked.
