This has been happening to several players of the Breaking Point Mod, Deathly rage has advised us to log this here as it is an issue with Arma 3

When the crash happens, i get a windows message: "Arma 3.exe - The drive is not ready for use;its door may be open please check drive A:"

After this i get the red desync chain and the "No message received for yx seconds" message. The A: drive listed as a floppy drive in my machine, but i don't have one built in it.

Seems to be happening at 15-20 minutes intervals each time, my friends in the game are stating they see a "client time out" message and I also see a red chain then the "no connection error Message".

The only way I can close Arma 3 is via task manager and ending the arma3.exe

I have checked the Arma 3 game files through steam twice and no issues and I have verified the Breaking Point pbo's and no issues all files are green.

System Specs:
6Gb ram
Nvidia GTX 670
