In this blog post, I’ll talk about the new NTFS health model for Windows 8 and our redesigned tool for disk corruption detection and fixing, the chkdsk utility.

We’ve all experienced the frustration that can be caused by an unexpected chkdsk that pops up while restarting a computer at home or a server at the office. Beyond the surprise, there’s the interruption while waiting for the process to complete and Windows to be available. With Windows 8, we provide quick resolution to these problems when they arise, putting the user in control and making systems more available and more scalable.

One of our key design goals for Windows 8 was to increase availability and reduce the overall down-time of systems; this feature, along with other storage features such as Storage Spaces (http://blogs.msdn.com/b/b8/archive/2012/01/05/virtualizing-storage-for-scale-resiliency-and-efficiency.aspx) and the new ReFS (http://blogs.msdn.com/b/b8/archive/2012/01/16/building-the-next-generation-file-system-for-windows-refs.aspx) file system, helps reduce the complexity of fixing corruptions and increases the overall availability of the entire system.
