Join Mike Meyers for an in-depth discussion in this video Hard drives, part of CompTIA A+ (220-901) Cert Prep: 2 Core Hardware.
- This is a hard drive.…Well, actually, this is a very old ATA…80-gigabyte hard drive, and the reason I'm using…an old hard drive is because this is the outside…of the drive, and this is the inside.…In this episode, Hard Drives, we're going to be…talking about this wonderful technology that's been around…for decades and has been the primary form of mass storage…for PCs for, well, pretty much since the beginning.…Now before we get too far into this, I want to get…some terms down, in particular, the term hard drive.…
A hard drive, or as CompTIA calls it, a magnetic drive;…or as I still call it, a spindle drive,…is this type of technology where we have…some form of rotational media.…In this case, it's these beautiful platters…and these platters actually store the data…with a little bit of magnetism;…and then we have that little voice coil, read/write head…going back and forth, which is both reading and writing data…on the fly.…Now if we take a look at the other side of this hard drive,…what you're gonna see is a bunch of electronics,…
The CompTIA A+ 220-901 exam is comprised of six key parts. The second, core hardware, is covered by this course. Instructor Mike Meyers explains the essential components and functions of motherboards, power supplies, and hard drives. He also shows you how to work with chipsets, troubleshoot electrical issues, implement RAID, and how to determine which hard drive technology to use depending on the circumstance.
Note: The six courses designed for the CompTIA A+ (220-901) exam preparation include core processing, core hardware, peripherals and building a PC, displays and printers, networking, and laptops and mobile devices.
- Working with motherboards, chipsets, and expansions
- Choosing a power supply
- Evaluating hard drive technologies
- Implementing RAID
- Troubleshooting issues
