Tài liệu How To Build Your Own Computer phần 6

In order to use your hard drive, it must be partitioned and formatted. If you
are building a system and putting a previously used hard drive into it, you may
not need to perform this step. But, on any new hard drive or one you are just
trying to start over with, you will need to do this.
Partitioning a hard drive means that you are creating the boot sector
(necessary to boot the machine) as well as dividing the hard drive into actual
drive volumes (C,D,E, etc). This action is done using the FDISK command.
FDISK should be included on your system disk and when you use it, it will
actually be run off of the floppy drive. If, for some reason, your system disk
does not have FDISK.EXE on it, get one that does.
