Working on my A plus and I need assistance with the following practice ques. please. Thank you much

A user has installed two new drives in one of the computers in the computer lab and has been unable to format disk 1 from the command prompt. The lab requires that disk1 be a dynamic disk configured with two partitions. The first partition must be 256 000MB in size and mapped to drive F. The second partition must be 512 000 MB in size and mapped to drive G. The new partitions must be formatted to ensure that users' files can be secured from other users and that disk must be configured for future redundancy.
Instructions: Conduct the necessary steps within disk manager to accomplish these tasks.
