D. sudo fdisk /dev /disk0

usage: fdisk [-ieu] [-f mbrboot] [-c cyl -h head -s sect] [-S size] [-r] [-a style] disk

-i: initialize disk with new MBR

-u: update MBR code, preserve partition table

-e: edit MBRs on disk interactively

-f: specify non-standard MBR template

-chs: specify disk geometry

-S: specify disk size

-r: read partition specs from stdin (implies -i)

-a: auto-partition with the given style

-d: dump partition table

-y: don't ask any questions

-t: test if disk is partitioned

`disk' is of the form /dev/rdisk0.

auto-partition styles:

boothfs 8Mb boot plus HFS+ root partition (default)

hfs Entire disk as one HFS+ partition

dos Entire disk as one DOS partition

raid Entire disk as one 0xAC partition

I hope I did this right. If anything is wrong, feel free to ask for me to change it.

3. The 5 Tb drive is connected via usb. I believe it is 3.0. And yes, I do have a 1 Tb Fusion disk, just for confirmation.

I'm sorry, but I think you misunderstood. I didn't want to install windows to my external hard drive, I was going to use it for the Flash drive part. I don't have flash drives lying around, so I was trying to use the hard drive I got recently to download Windows on my Mac.

Or did you mean I can't use the hard drive for that purpose.

Sorry if I didn't give enough info.

Okay then, I see how it works. Thank you for clearing things up.
