System Administration, Week 2: Physical Disk Structure
We'll take a quick look at what a hard disk drive actually looks like. This helps us understand addressing schemes such as CHS and LBA, what physical aspects affect hard disk performance, as well as partitioning requirements. While a lot of this is tied to old magentic-spinning-platters drives, it explains a lot of assumptions partitions and file systems make even if using SSDs.
System Administration, Week 2: Partitions
In this video, we talk about how to divide a single disk -- physical or virtual -- and how the partitions relate to the physical structure of the disk. We show examples partitioning disks on NetBSD, OmniOS, and Linux using the disklabel, fdisk, and format tools.
