Partitions, Volumes, and File Systems 0:00-0:22 Most long term storage in computer is done on a hard disk. In this lesson, we'll look at how to prepare a new hard disk drive so that you can organize and save data to it.

When we add a new hard disk to a computer, the computer cannot use that hard disk for saving datauntil it's prepared, so that the operating system knows how to identify and save files to the hard disk drive. Partitions 0:23-0:52 The first step in preparing the hard disk drive is to create a partition on the hard disk. A partition is a logical division of the hard disk drive. A portion of the hard disk is carved out and prepared to save data. You can create a partition that takes up the entire hard disk or, you can create multiple partitions on a single hard disk. For instance, I can divide this hard disk into two partitions. Any space not assigned to a partition is labelled as unallocated space. When you purchase a new hard drive, the entire hard drive is generally unallocated. Volumes 0:53-1:47 Before you can use a partition for saving data, you need to create a volume. A volume is a single storage space within a computer. A volume can cover that entire partition or we can create a volume that spans multiple partitions. This is useful if I've defined a partition to use this much of the hard drive with some unallocated space. I could add space to that volume by creating a new partition and assigning that partition to the volume. I could also take another hard drive and create a partition on that second hard drive and assign that space to the volume as well. Because partitions and volumes are logical structures, I can create a storage space that uses multiple chunks on a single drive or multiple chunks on several drives. When we define a volume, the operating system assigns a drive letter to the volume. For instance, the volume could be assigned to the c drive or the d label. This helps us keep track of different volumesthat have been assigned on the operating system. Formatting 1:48-2:33 The last step you need to preform is formatting. Formatting prepares the disk area with the rules and the specifications for how data is saved. The file system identifies how files are located on a drive, and identifies any additional features that are available for storing and managing your files. Windows supports two different formats for hard disks. Either the FAT32 file system or NTFS file system. In most cases Microsoft recommends that you choose NTFS for the system of your hard drives. NTFS has some advantages over the FAT32 file system, for instance, it supports larger disk sizes, larger file sizes, disk compression, encryption, disk quotas, and folder and file permissions. In some cases there is a performance benefit from using NTFS over FAT32.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
