The correct answer is C. Convert both drives to a dynamic disk. Windows Disk Management only exposes mirroring (RAID 1) options for dynamic disks. Basic disks, regardless of file system, do not support software RAID volumes through the GUI.
Question
A user has a computer with a 100GB IDE hard drive formatted as a single FAT32 partition. This drive is only used to store data. The user adds a second 100GB hard drive and wants to mirror the two drives. When the user goes to disk management there is no option to mirror the drives. Which of the following will resolve this issue?
Options
- AConvert the partition to NTFS.
- BChange the partition to be an extended partition.
- CConvert both drives to a dynamic disk.
- DChange the partition to be the active partition.

Why each option
Windows Disk Management only exposes mirroring (RAID 1) options for dynamic disks. Basic disks, regardless of file system, do not support software RAID volumes through the GUI.
Converting FAT32 to NTFS changes the file system but does not change the disk type from basic to dynamic, so the mirror option remains unavailable.
Changing to an extended partition is a partition type change on a basic disk and has no effect on enabling dynamic disk RAID features.
Windows software RAID features such as mirrored volumes are only available on dynamic disks. A basic disk, even with NTFS formatting, does not expose mirror, spanned, or striped volume options in Disk Management. Converting both drives to dynamic disks upgrades the disk type to support these multi-disk volume configurations without reformatting the data partition.
Setting a partition as active marks it as the bootable partition and has no relationship to enabling mirroring in Disk Management.
