I have an older MacBook Air (Mid 2011) now running High Sierra. I am backing up documents, pics, and videos to an external HD that is formatted in exFAT. I use my MBA and a Lenovo system interchangibly and need files accessible on both, hence exFAT. I noticed size and size on disk in Lenovo to be tremendously different (400 GB takes up 800 GB space for example).
In trying to figure out what was happening, I came across an unusual file system block size on my MacBook, at least as far as I am reading it.
I followed the steps shown on this page What are the sector sizes on Mac OS X?.

Apparently the 4096 expected file size is 4194304 instead while the Device Block Size and Allocation Block Size are both 4096.
Could you tell me if I'm reading it correctly, that 4194304 is extremely large? If so, how do I fix it?
Thanks in advance.
