Anatomy of a Hard Disk Drive

Filed under
Hardware

We disassembled a hard drive to show you the main components you will find on a hard drive.

Hard drives have two kinds of components: internal and external. External components are located on a printed circuit board called logic board while internal components are located in a sealed chamber called HDA or Hard Drive Assembly.

You cannot open a hard drive or you will make your drive unusable. Hard drives are assembled in clean rooms (cleaner than surgery rooms) and then sealed. Any particle of dust inside the HDA can destroy the surface of the discs, because the discs spin at a very high speed (at least 5,400 rpm nowadays). This would not only lead to data loss, but also the physical destruction of the disc surface.

So, there is no serviceable part inside the HDA - at least for the regular technician. Only data recovery companies with clean rooms can open and replace components inside the HDA. On the other hand, the logic board can be replaced by any technician and this is one is a powerful procedure for recovering data from dead drives. We'll post a tutorial on this subject in the future.

Anyway, before exploring the components located both the logic board and inside the HDA, let's take a look on the connectors found on a regular hard drive.

Open Source Software A Core Competency For Effective Tech M&A

Imagine your company just acquired its competitor for $100 million. Now imagine the company’s most important asset – its proprietary software – is subject to third-party license conditions that require the proprietary software to be distributed free of charge or in source code form. Or, imagine these license conditions are discovered late in the diligence process, and the cost to replace the offending third-party software will costs tens of thousands of dollars and take months to remediate. Both scenarios exemplify the acute, distinct and often overlooked risks inherent to the commercial use of open source software. An effective tech M&A attorney must appreciate these risks and be prepared to take the steps necessary to mitigate or eliminate them. Over the past decade, open source software has become a mainstay in the technology community. Since its beginnings, open source software has always been viewed as a way to save money and jumpstart development projects, but it is increasingly being looked to for its quality solutions and operational advantages. Today, only a fraction of technology companies do not use open source software in any way. For most of the rest, it is mission critical. Read more
