Join Mike Meyers for an in-depth discussion in this video Dynamic disks, part of CompTIA A+ Exam Prep (220-902) Part 2: Putting Pieces Together.
- For the first few decades of the PC world,…the only real partition table we had to use…was old MBR.…Now MBR has a lot of limitations,…and the four partition limit is just, like,…one of the very least of those problems.…So around the year 2000,…Microsoft unveiled a new kind of partitioning.…Now I gotta be careful with this…because it's not really a new partition table…that replaces MBR,…MBR's still there,…but Microsoft creates its own partition table,…but not on the partition table,…but really his own little Operating System-level partition.…
This is known as Dynamic Disks.…Dynamic disks predate GPT,…but they came after MBR.…We still use dynamic disks on even the most modern systems,…so let me give you a quick run down,…and show you just a little bit…about how dynamic disks work.…What I've got here is a whole bunch of drives…on this particular system.…What I want you to see is over here on the left.…Do you see that word "basic?"…When you see the word basic in Disk Management in Windows,…that means that this drive is not dynamic.…
In Part 2, Mike Meyers helps you understand all the pieces that comprise the modern computer: RAM, power supplies, hard drives, and peripherals. Though 220-902 focuses on operating systems and software, a solid foundation in hardware will help you understand how all the pieces fit together. In Chapter 5, Mike shows how to build a basic PC, and install a fresh copy of Windows.
