[ ]Configure sector sizes appropriate for various workloads [ ]configure GUID partition table (GPT) disks [ ]determine when to use NTFS and ReFS file systems

  1. When you first add a new hard disk the first step is to mark it as online.
  2. Next, initialize the disk.
  3. Select Partition style
  4. Create a volume on the disk
  • right-click in the unallocated space of the disk and then click Create Simple Volume

Comparison of MBR and GPT Disks Also note other partition options may be present

  • System Reserverd Partition
  • Boot Configuration Store
  • BitLocker Drive Encryption
  • Windows RE

++MBR++ (Master Boot Record)

  • 2 TB max
  • Information about the disk are stored in the first disk sector
  • Up to 4 Primary Partitions (workaround 3 primary, 4th extended then add logical drives)
  • Been around since 1983 PC DOS 2.0, pre windows, & provides compatibility. X86 & X64 Based computers.
  • Creates a boot sector at the begeining that points to the locations of the partitions & provides a boot loader for the operating system. Single POF if boot sector becomes corrupt.

++GPT++ (Guid) Partition Table -- globally unique identifier

  • part of the UEFI Unified Extensible Firmaware Interface developed in the 1990s to replace BIOS.

  • Been around since 1990s, 2003 SP1 and later Partitioning information spread throught the disk along w/a CRC.

  • Supports Volumes up to 18 Exabytes --128 partitions on each disk --supports disks that go up to almost 1 Zettabyte (ZB) -- which is about 1 billion TB!

Tools to modify disks -- Disk Management -- Diskpart.exe -- Resize-Partition command (PowerShell)
