Windows 2012 and the new VHDX format are stated to have full support for native 4k sector drives.
However if I create a VHDX file on hyper-v 2012 with native 4k (logical + physical sector sizes set to 4k), a windows 2012 Standard guest OS will not install, it gives the error:
Windows cannot be installed to this disk.
This computer's hardware may not support booting to this disk.
Ensure that the disk controller is enabled in the computer's BIOS menu.
however if I set it to a 512e VHDX where the logical sector size is 512k but the physical is 4k then it works fine.
... is the issue that the IDE controller in hyper-v 2012 doesn't support 4k sector drives?
I have read there is a negative performance impact when using 512e so I was hoping to take full advantage of Windows 2012 and native 4k sector drives.
thanks
