Thanks Fam
No error on my guest / host
Disk usage in Explorer is exactly what it supposed to be this is where it is strange...

Hi,

My D: drive (74GB) has 2x 32GB files used for a program to store data.

I realized that my product starts doing FIFO (erasing old data to be
able to write fresh data) as soon as the space used is more than
4GB. It is like I got the same limitation than a FAT drive, my
product detects that the disk is full as soon as more than 4GB are
used on the disk.

Any error message in guest/host?  What does Windows Expolorer say about the
disk usage?
