Managing Disks
Troubleshoot with Disk Management
You can use the Disk Management utility to troubleshoot disk errors through a set of status codes; however, if a disk will not initialize, no status code is displayed. Disks will not initialize if there is no valid disk signature.
The problem with disk errors is that you don't know when a disk fails or which disk failed. Disk Management can help you with this. When disks have problems or errors, status codes get assigned. Knowing what these codes mean will help you determine what the problem is but, more importantly, what steps you need to take to fix the problem.
