Your Hard Drive Is Dying, Here Are Several Reasons Why!

How depressed do you think you would be if all of your pictures, music, movies, documents and more just disappeared into thin-air one day, NEVER to be recovered?
If you’ve never asked yourself what you would do in such a scenario, chances are you are unprepared to experience your hard drive dying! The first thing you should know if you don’t already, is exactly what a hard drive is. It’s a hardware unit that is built with disks called “platters.”
Platters are stacked on top of each other, and have heads that are below and above each hard drive platter. When these platters spin, the heads of the drive move “in and out”, toward the center of the platter, then towards the edge; in order to access the actual surface of each platter. To summarize, a hard drive is made of moving parts that contain electromagnetic energy and circuitry.
In other words, a hard drive is constantly creating friction that will eventually destroy it. Yes, EVERY hard disk will fail at some point, the main concern is WHEN?
Here Are The Top 5 Warning Signs Of Your Hard Drive Dying:
Grinding noises, rubbing sound, scrubbing and clicking sounds
A good way to tell if your hard drive is dying, is noises coming from the computer that resemble rubbing (check to ensure the rubbing isn’t a computer fan or ROM drive). Noise is a symptom of a mechanical issue in a drive which will eventually lead to data loss. Clicking sounds are warnings of a mechanical issue with a drive, and may
drives fail prior to the clicking sounds beginning, or simultaneously.
Another indication of a hard drive dying is grinding, since the arm containing the head of the drive, literally touches the platter at that point. This creates extra Friction and substantially harms the “read” surface of the drive containing the data.
Please don’t forget that hard drives can create sounds that one may mistake for grinding, but normal hard drive operation does not make a grinding, or scrubbing or clicking sound. I highly recommend that you learn how your “healthy” hard drive sounds, so you can recognize any strange sounds and get help immediately!
Your files vanish “into thin air” for no reason
Another big sign of your hard drive dying, is your files disappear without you deleted them! A failing hard disk usually will have “read and write” errors, which are definite causes of data that disappears or becomes corrupted.
It is important to remember that malware (Trojans, viruses etc) can cause corrupt or deleted files, BUT you should always check for virus infections (when data is deleted), with good software BEFORE you begin to suspect your hard drive dying.
Your hard drive is not being detected by your PC
Here is another sign of your hard drive dying; when your computer can’t detect your drive at all. Let’s imagine to power on your PC, then the logo screen (POST) appears immediately after turning on the computer and reads “Hard Disk Failure”, or a related error.
In that situation, your hard drive could have loosened or isn’t fully connected, or it could have the wrong “jumper” setting or configuration settings (in BIOS), OR the drive could have totally died and is no longer being detected for that reason.
Here’s another scenario; your PC powers on and loads perfectly well. All of a sudden, you see a black screen that has a blinking cursor. You try everything that you know, to get your computer to boot. You try to do a “system recovery” to restore your PC back to the factory defaults but the computer won’t start the process.

Computer Hardware Guide: The Best System for You

There are many different types of computer systems currently available, so how do you choose which one is right for you? The answer to this lies in what you intend to use your computer for and how many tasks you need to do at the same time. Here is a rough guide to the type of computer system you need to accomplish common tasks:
Netbook Computer
- Ideal for word-processing and internet browsing whilst on the move
- Not so ideal for gaming applications as these typically require more processing power, although if you only wish to play Solitaire or some of the other games built into Microsoft Windows, these should work just fine.
Laptop Computer
- Ideal for business users who need to manage multiple tasks at once, i.e. sending emails, writing presentations and writing reports for example.
- Not so ideal for gaming applications or for running applications requiring a high amount of processing power, i.e. a large amount of data analysis at the same time.
Desktop Computer
- Ideal for processor intensive applications such as online gaming and data analysis, as well as anything else that is not suitable usage for netbooks or laptops.
- Not so ideal for someone who needs to access data on the move or who doesn’t have much space to store a computer.
There are, of course, larger types of computer hardware systems that are intended for use by large businesses and organisations, such as mainframe computers. Read the rest of this entry »
