Managing and Troubleshooting Hard Disks

Disk status is also listed for disks and volumes. The settings you will find are listed below:

  • Healthy (volumes) and Online (disk) require no action. If the disk is dynamic and marked Missing or Offline, right click and choose Reactivate Disk.
  • Failed: Incomplete Volume requires that additional disks in set (such as volume or stripe set) must be added.
  • Foreign. If you see this, it means that you have added a disk from another system to the machine. You must right click and choose Import Foreign Disk in order to make the disk accessible. (only exists for dynamic disks)
  • Failed Redundancy means that a volume in a Mirrored or RAID 5 volume has failed and needs to be replaced.

If you do replace a disk, choose the Rescan Disks option to have the system register the disk.

Another thing that has changed from NT 4 is how drive letters and paths are managed. First off, the system will not change drive letters when you create new volumes, and will even edit the Boot.ini file for you (thank goodness). You are no longer constrained by local drive letters either. Windows 2000 supports mounting local drives to an empty folder instead of a letter, similar to Unix. Only local mounts are supported. Drive letters can be changed to mount points and vice versa using Disk Management. One last not e about the Disk Management program is that it also supports the remote management of disks, by focusing the tool on other machines instead of the local system. Only Administrators or Server operators can use this functionality, and it still cannot be used to remotely delete a volume/partition containing boot or system files, or the active page file.
