Ok so about a month ago my hard drive began to fail. It was not completely gone but it wouldn’t boot either. So that is what my next series of posts is going to be about.
The series is going to be as follows.
1. What Causes Hard Drive Failure
2. How to prevent data loss
3. What to do when your disk fails
4. The conclusion.
So lets get started…
WHAT CAUSES A HARD DRIVE TO FAIL
Just like a car your hard drive will eventually fail. Moving parts break down over time. The time it takes for it to fail is different for every drive. I have a drive in my computer right now that has been working for over 5 years while the old drive I just pulled out lasted just over a year.
The internals of a drive are very sensitive the drive heads [what reads the data] float a micron above the platters [the disks that hold the data] and when a drive is put through a lot of vibration the heads can become offset causing a hard drive to fail.
Heat is also a problem that can cause a hard drive’s life span to be shortened. It is important to make sure your computer is in a cool room and there is enough air flow inside the case of your computer.
Static is a major computer killer. This one mostly only applies to people working on computers. It is extremely important to make sure you don’t transfer static to your hard drive. When ever installing components into a computer make sure to wear a static wrist band. If you don’t have one make sure to touch the side of your computer.
Power Surges are also a point of failure. To help prevent this make sure that your computer is ALWAYS connected to a name brand surge protector. [not the cheap ones you can get at the dollar store]. Most surge protectors come with some sort of insurance. For example if my computer failed while plugged into its surge protector and its because of a power surge I have upto $100,000.00 of coverage on it.
In my case my drive had a head / platter issue. When it would try and read I could hear a clicking sound from the heads trying to read.
In part 2 I am going to talk about Data Recovery Hospital and how to prevent data loss mostly by way of proper backups and disk clones.
