Linux Storage Made Easy: Drives, Firmware, & Partitions Explained
In today's lesson of our Linux series, we are diving into the fundamentals of Linux Storage.
Understanding how your operating system interacts with storage hardware is a critical skill for any Linux user or admin. In this video, we break down physical drives, system firmware, partitioning schemes, and essential command-line tools to help you inspect and manage your disks.
🔑 What You’ll Learn in This Video:
Storage Hardware Basics: Physical 2.5" SATA hard drives, data vs. power connectors, and how drives interface with the motherboard.
Firmware Fundamentals: The difference between Legacy BIOS and modern UEFI firmware.
Partition Schemes Compared:
MBR (Master Boot Record / DOS): 32-bit, max 4 primary partitions (up to 15 total), and 2 TiB max partition size.
GPT (GUID Partition Table): 64-bit, up to 128 partitions, 8 billion TiB max partition size, backup partition tables, and native UUID support.
Linux CLI Hands-On:
How to check if your system booted using UEFI or Legacy BIOS.
How to list block devices and customize output columns using lsblk.
How to inspect disk partition tables and labels using fdisk.
Why MBR partitions show pseudo-UUIDs in Linux.
