When I run, I've got a pop-up message on windows - fio.exe has stopped working ...

NOTE: If I remove zoneskip and zonesize- everything works.

Could you please help me understand what am I doing wrong?

Thank you very much

I saw fio crash yesterday when I ran it on a disk that contained 
volumes. Windows prevented writes to that area of the disk and fio 
crashed - I'm working on fixing it today.

Thank you so much my friend, but I don't have volumes... I am using the whole physical disk. Great when you have a fix I will download and I will test.

It's a divide by zero bug in eta.c:160:

bytes_total /= (td->o.zone_skip / td->o.zone_size);

It seems that td->o.zone_size isn't getting set via the zonesize setting 
in the job file and so the default of the entire size is used.
