List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 28 Oct 2015 17:06:23 -0000 Can anybody explain why FreeBSD 10.2 has so many bogus disk drives when run using HyperV on Windows 10. I defined two SATA hard drives but I have 19 da devices (da0-da18). Must oft hese devices have 0 heads, 0 sectors, and 0 cylinders. Is the issue with the FreeBSD hv_storvsc(4) driver or with the underlying HyperV?
