You install your boot volume on volume C on your Windows 2000 Server computer. You mirror volume C on dynamic Disk 1. Two years later, during routine server maintenance, you open Disk Management and find that the status of volume C is Failed Redundancy. The status of Disk 1 is Missing. You attempt to reactivate Disk 1, but the status of volume C does not return to Healthy. What should you do next?

A

Replace Disk 1 and restart the computer. The mirror will automatically regenerate

B

Remove the mirror on Disk 1, replace the disk, and then add back the mirror to the new Disk 1

C

Replace Disk 1 and copy all data from volume C to a new NTFS primary partition on the new Disk 1. Restart the computer

D

Rescan the disks, remove the mirror, and delete the data on Disk 1. Then re-create the mirror

E

None of above
