Microsoft has redesigned chkdskutility – the tool for detecting and fixing disk corruption.
Microsoft introduced a file system called ReFS, which does not require an offline chkdsk to repair corruptions – as it follows a different model for resiliency and hence does not need to run the traditional chkdsk utility. The disk is periodically checked for file system errors, bad sectors, lost clusters, etc., during Automatic Maintenance and you now no longer need to really go and run it. In fact, Windows 8 now even exposes the state of the file system and disk via the Action Center or under the Drive properties in File Explorer. If potential errors are found, you will be informed about it.
