- FMIFS: QueryDeviceInformation(): Use more specific types and improve documentation.
Follow-up to commit 4838d7bd56.
- FORMAT: wmain():
* Zero the correct variable. Addendum to commit c5a9f22d4e.
* No need to zero the whole volumeName array. Follow-up to commit 358fecdcf0.
QueryDeviceInformation returns more reliable volume length and works
with unformatted volumes. It will return volume length only on ROS and Vista+ however,
so also keep the GetFreeDiskSpaceExW as a fallback for XP/2003.
