Hi DG2708o1 (whoa - that's a tough name to remember...),
With an advanced data structure like yours, I would suggest that you use Datalog files instead of simple binary files. Using a Datalog file, you can save multiple 3D arrays in the same file and easily retrieve them without any problems.
I have attached an image of what you will need to change your VI to write to a Datalog file instead of a simple binary file, and on the same image you can see what it takes to read the file. And yes; I tested it and it works like a charm!
Have fun!
