How data is stored on a hard disk

How data is stored on a hard disk

When a file is saved to a computer, the data is stored in the magnetic coating of the hard disk. This magnetic coating on the plates is the “glue” that holds your data. Any damage to this magnetic coating means that there is a loss of data, as each piece of missing coating contains data. Thus, a dish lacking some of that coating has a better chance of a successful data recovery, as opposed to a plate that had massive amounts of that magnetic coating removed or destroyed.

Hard disk trays, or spindles, are rotated by an electric motor. The speed of this rotation is measured in revolutions per minute (RPM) and the higher the hard disk performance … the higher the RPM that increases the reading and writing of data on the plates. Any surface contact with the discs can cause serious damage to the magnetic tape that contains the data. This includes dust, fingerprints, water and, most important of all, hard drive heads. Dish damage is the most serious type of damage to cause hard drive failure.

Heads (Head Crash) When the hard disk is not being used actively, the heads stop until the hard disk needs to read or write data again. It is when this head moves out of the super thin air cushion between the dishes that causes the head to collide and touch the plate of the hard disk.

Firmware Firmware is the program instruction located on the printed circuit board (PCB) chips. Each firmware revision is specific to your hard drive type and each hard drive can go through dozens of firmware revisions to increase the hard drive performance of that particular manufacturer. The older the hard disk, the harder it would be to find a functional firmware for that particular hard disk model.

Printed Circuit Board (PCB) The hard disk PCB is the hard disk electronics that manages and operates the hard disk. If a printed circuit board is damaged, it is often replaced by an identical printed circuit board with the same firmware on the original hard drive. Typically, PCB damage is caused by water or fire, but there are other reasons why the PCB would fail. And often a failed PCB affects other aspects, such as firmware or heads.

How data is stored on a hard disk

Types of Hard Drive Failure

In general, when a disk drive fails, it is due to one of the following causes:

Media failure also known as head fall (as described above), the hard disk heads touched and physically damaged the magnetic coating of the dishes.

Mechanical failure In general, any electronic fault on the hard disk falls into this category. Fire, water, electrical damage to the hard drive would require replacing parts.

PCB Failure as described above, PCB failure falls into the type of mechanical failure and can usually be “switched” by an identical PCB for that specific type of hard drive. Along with the correct firmware for this disk drive, a PCB replacement can be a difficult type of hard drive repair if the hard drive is an older model.

Logical Drive Failure this type of hard drive failure is usually the least damaging to the data. This type of error usually means that the computer’s operating system (or utilities) can see the drive, marked it as unallocated space, but because the computer’s MFT is corrupted or corrupted, the data can not be read. Hard drive failure of this type is not as destructive and the chances of a complete and successful data recovery are high.

Electronics Assemblies – PCB assembly

Product Assembly

Whatever the industry, there is a tendency today to try to find a cost-effective solution to final product assembly by cutting out all of the unnecessary double-handing of goods and component parts.

Having found a suitable sub-contract sheet metal engineering company to make up the parts and housings say it seems a waste to then have the expense of having it all shipped back to you to be put together, finally inspected, labelled and boxed ready for despatch etc.

With some of the more advanced sheet metal engineering companies offering an extensive range of “additional” services inclusive of powder coating and even, in some cases, plastic vacuum forming, it may not be too surprising to also find that there are those who have taken the extra step to offer a full one-stop shop service.

For many years now there have been plenty of companies offering the Printed Circuit Board type final assemblies, but what we are talking about here is the much bigger picture:

  • Mechanical Assemblies
  • Electromechanical Assemblies
  • Electronics Assemblies – PCB assembly / Wiring Looms / Security Systems

Product Assembly

Why ship large bulky items back to have the “innards” located, or all the electronics fitted etc – why not have it fully assembled in the same place where the majority of the components and sub-assemblies have been manufactured?

Of course no company that I know of is going to offer this service purely for the joy of working, and they will make a charge for the service, BUT if it is faster and easier and cost-effective in terms of not shipping bulky parts back, risking transit damage, employing assembly staff (this way you only pay when you are using them) and having to maintain your own QA and despatch / warehousing systems then the Complete Service option may well suit you.

Not everyone is going to be able to offer this level of service of course, but it does indicate a willingness on the part of the supplier to go that extra mile to offer a fully inclusive service – however you must check for yourself that they have the resources, the systems and expertise, the warehousing space to accommodate your goods and the distribution network capable of meeting your customers requirements to your satisfaction.

The Importance of Electronics Manufacturing Companies

The Importance of Electronics Manufacturing Companies

Companies have a great many incentives to invest heavily in product innovation. Electronics is an extremely competitive business, and each product released is subject to intense scrutiny and thorough, detailed and honest reviews, both online and offline. There is a strong incentive to ” get it right” with regard to new products, as they may have the power to make or break a company.

Take for example the Nintendo Wii – before the Wii, Nintendo was on the way down, with dropping sales and an image that was somewhat old hat. No longer. The Nintendo Wii has catapulted the company into the stratosphere, and has done wonders for its image. Nintendo is where it is today because of its investment in innovative new products. Likewise, should a company stir up some hype about a product which turns out to be disappointing, the effect is just as strong but in a negative direction. Remember the NEO GEO pocket? Thought not!

The Importance of Electronics Manufacturing Companies

But aside from this death or glory perspective, there is a large grey area. Companies release many generic products in the electronics line which are not clearly better than their competitors products. In this large grey area, decisions regarding its products are the best often fall to dedicated fans of a certain type of product – for example, Blu Ray players for home theatre enthusiasts. Such enthusiasts will post their ideas online, or in the popular Which? magazine.

To cut a long story short, all good electronics manufacturing companies understand the critical importance of the online reception of their products. When people aren’t sure whether a new product is any good or not, they usually just type it into Google and read the reviews on the first page. For an electronics company, the nature of their press online is extremely important.

Initial step of rapid prototypes for manufacturing

Initial step of rapid prototypes for manufacturing

Rapid prototyping is a software development procedure in which physical objects are constructed robotically by SFF or solid free-form manufacturing. In the process of rapid prototyping, you can quickly build a prototype or performance model and test its functionality, performance and performance. The latest features or ideas can be illustrated well in the prototype and the initial comments of the users can be collected with respect to the product. There are several advantages of rapid prototypes.

Benefits of Rapid Prototyping: The significant advantages of rapid prototyping include reducing the cost and risk of the project. Generally, one or more prototypes are developed in the software development process in a series of incremental and iterative steps. Each prototype that is manufactured is based on the performance of the previous designs and is a corrective process by which the defects or problems of the previous design are corrected. The product is prepared for production when the prototype is refined according to requirements and meets all design objectives, such as manufacturing capacity, strength and functionality.

Rapid Prototyping fields cover automobiles, electronics, bathroom equipment, toys, kitchen utensils, telecommunications equipment and household items. Also ODM and OEM are related to the manufacturing industry. Look closer OEM vs ODM.

Initial step of rapid prototypes for manufacturing



OEM stands for Original Equipment Manufacturer, but this can also be called as Factory Original when it comes to Auto parts, bicycle parts and even Technology parts. This original equipment manufacturer refers to the company / organization that initially manufactured the goods that consumers are buying. We offer prototypes to product manufacturing services whenever you offer us design sketches.


The manufacturer of OEM/ODM wants to complete the defined criteria before obtaining your powder packing machine and vertical packing machine that suits your needs.
