Hello,
I'm running Win 8, upgraded from Win 7, and I first noticed that I could not run LocalDB when I tried to create my first LightSwitch app in VS 2012. The error reported there is that it cannot start, but later I found in the error logs the following output:
2012-09-04 12:28:02.43 spid4s Cannot use file 'C:\Users\UserName\AppData\Local\Microsoft\Microsoft
SQL Server Local DB\Instances\v11.0\master.mdf' because it was originally formatted with sector size 4096 and is now on a volume with sector size 3072. Move the file to a volume with a sector size that is the same as or smaller than the original sector size.
Go to the complete details ...
