Thumbs up Redesigning chkdsk and the new NTFS health model (MSDN Blogs > Building Windows 8)


We’ve written about tons of improvements in the OS kernel, networking, and file system. While for most client PCs, the tried and true chkdsk utility is one we rarely use anymore except in very rare circumstances, we are using Window 8 as an opportunity to improve this utility. We wanted to focus on rethinking how the utility works to increase availability and reduce downtime due to chkdsk operations. In looking at the real world usage of chkdsk, we note that corruptions are exceedingly rare though running chkdsk is not.

While we’ve worked hard to reduce the manual invocation of disk tools (like defrag) we know many prefer to run them manually “just in case” and so we worked to improve the overall throughput of chkdsk, since running it reduces availability of the machine. With disk capacities becoming extremely large and multi-disk systems more common, we wanted to improve the utility. Kiran Bangalore, a program manager on our core system team, authored this post.
