Study Notes
Computer Essentials - Partitions
- Partitioning is dividing a physical hard drive into smaller units called partitions.
- Every hard drive needs at least one partition.
- Multiple partitions improve performance (HDD only), simplify backups, and allow for multiple OS installations.
- The partitioning process is identical for all disk types (HDD, SSD, hybrid).
Drive Types and Partitioning
- The disk drive partitioning process remains consistent across various disk types (HDD, SSD and hybrid drives).
- The generic term "disk drive" or "drive" encompasses mechanical hard drives, solid-state drives (SSDs), and hybrid drives.
Preparing a Disk Drive for Use
- Step 0 - The disk drive needs to be ready for partitioning.
- Step 1 - Create an empty partition on the disk.
- Step 2 - Format the partition to establish a file system. This lets the operating system store files and folders on that partition.
Partition Methods
- MBR (Master Boot Record): located at the first physical sector of the hard drive holding the executable code that boots the active partition and a partition table identifying each partition.
- MBR supports up to four bootable partitions.
- Each MBR partition has its own drive letter, boot sector (OS boot information), root directory (the first folder), and FAT (File Allocation Table—listing files and their attributes).
- GPT (GUID Partition Table): uses GUIDs (Global Unique Identifiers) for each partition.
- GPT can support up to 128 partitions of varying sizes (with a maximum practically achievable limit of 9,000,000 Terabytes).
- GPT organizes partitions using logical block addresses (LBAs) instead of sectors, which is essential for non-HDDs.
Partition Methods - MBR (Details)
- Primary Partition: Essential when installing an OS; it's a regular partition that can boot.
- MBR supports 4 primary partitions, with only one being active (starting the system).
- Extended Partition: Replaces a primary partition when sub-partitions (logical partitions) are to be created.
- Logical Partitions: Can't be active but can store data and can be housed within an extended partition.
Partition Methods - MBR (Examples)
- Example 1: One drive, Four Primary partitions.
- Example 2: One drive, Two Primary partitions, one Extended partition with six Logical partitions, then an additional Primary partition.
Drive Letters
- Every disk volume is assigned a drive letter for identification (e.g., C:).
- Hard drives usually start with drive letter "C:".
- Drive letters are assigned in a specific order: first to primary partitions, then logical partitions, and then other connected storage devices (e.g., CD-ROM, DVDs, and external drives like flash drives).
- Drive letters A: and B: are designated for floppy disk drives.
Formatting Partitions
- After partitioning, the drive must be formatted.
- Formatting creates three essential disk structures: partition boot sector, two copies of the File Allocation Table (FAT), and a blank root directory.
Types of Formatting (Why Format the Partition?)
- Low-level (full format): Performs a surface scan to validate the physical disk, locate bad sectors, and create a reliable disk.
- High-level (quick format): Clears the file allocation table (FAT), but doesn't check for disk errors.
Dynamic Storage/Disks
- Dynamic storage: Works only with Windows.
- Defines disk space as volumes (similar to partitions) with no volume limitations.
- Volumes can span across several drives.
- RAID support (e.g., mirroring, striping).
- Simple Volumes are an alternative to primary partitions in Windows.
Partition Software – OS Included Software
- OS-included Disk Management (Windows) with a graphical user interface.
- FDISK/DISKPART (older Windows versions and Linux).
Partition Software – 3rd-Party Software
- 3rd party software can often allow resizing, splitting partitions, converting file systems, and moving partitions without erasing existing data.
- Examples include EaseUS Partition Master, Paragon Partition Manager, and GNOME Partition Editor/GParted.
Summary
- Hard drives require partitioning before use.
- Partitioning methods include MBR and GPT.
- Primary partitions are for OS installations.
- Logical partitions store data.
- A high-level format creates a file system.
Conclusion
- The lesson covered partitioning methods, examples, drive letter assignments, formatting techniques, and related software tools.
