When an offline chkdsk repair is required, users will be notified via the Action Center. In Windows 8, chkdsk scans are automatically scheduled to be performed during a maintenance window, i.e. If the errors are verified to be genuine, an online scan of the volume catalogs the issues so that they can be fixed at a later point without scanning the entire volume offline. When the file system driver detects corruption, it verifies whether the corruption is genuine using the new Spot Verifier service. Windows 8 and Server 2012 introduce a new capability that allows the file system to verify whether an issue is caused by a transient memory error or whether there is genuine file corruption on the disk. The number of issues that can be fixed online has increased in Windows 8 and Server 2012 and is further improved in Windows 8.1 and Server 2012 R2. In the majority of cases, NTFS is able to self heal when a corrupt file is detected, while keeping the volume online. Help! How do I fix disk errors in Windows 8 and Windows Server 2012?Ī new NTFS health model in Windows 8 and Windows Server 2012 monitors drives for corruption, repairs many issues while volumes remain online, and offers fast offline repairs with spotfix.
