13.8.3. How to Update the User Volume Note
The data update operation for MIC is accomplished by overwriting the current data with new data, and this means
that you have to rewrite the entire User Volume Note even if you want to change only a part of it. Always check
whether the UVN exists by interrogating the drive about the size of the UVN: you will get 0 byte size if there is no
UVN.
SDX-450V reports an error condition (illegal parameter list length) if the User Volume Note Data Size is ZERO.
