A. In Windows 2000, if you replace one part of a RAID 5 set as a result of faulty hardware, the volume won’t lose any data because of the stored parity information. However, you must replace the broken disk to re-enable the RAID 5 set’s fault-tolerant ability.

After you replace the bad disk, complete the following steps:

  1. From the Start menu, select Programs, Administrative Tools, then the Computer Management Microsoft Management Console (MMC) snap-in.
  2. Expand the Storage branch, and select Disk Management.
  3. Win2K still shows the removed disk as Missing.
  4. Right click an element of the RAID 5 volume, and select Repair Volume… from the context menu.
  5. From the list, select a disk to use as the bad disk’s replacement and click OK.

  6. Win2K will show the set as regenerating.

Your RAID 5 set is now fault tolerant again, but you need to remove the RAID5 partition from the missing disk.

If you had other partitions on the disk that you removed, you can right click the partitions and select Delete Volume… to remove them. You should now right click the Missing text and select Remove Disk from the context menu.

If you ever reuse the original disk, Win2K displays the disk as Foreign. To read this disk, see 'Q. How do I import a foreign volume in Windows 2000?'
