As you will find out I like to keep my blog pretty simple and easy to understand. In my last blog I wrote about how important it is to back-up your data. In this blog I want to describe symptoms of when a hard drive may be going bad.
There are primarily two forms of hard drive failure, logical and physical. Logical failures are usually a result of file-system corruption. This can occur due to a virus, accidental deletion of key files or registry components, and in some cases even electro-static discharge. In most cases of logical failures, the drive is still recognized by the system BIOS, but will not boot. In most cases, your data should still be intact on the drive even though it may appear to be inaccessible.
If the system BIOS does not detect the presence of the hard drive, then chances are a physical failure has occurred. Physical failures can be the result of a failed spindle motor. Spindle motor failure can result in excessive heat to a bearing failure. Excessive heat will result in expanding the drive shaft and therefore seize the spindle motor and the hard drive will become inoperative.
Another physical issue that sometimes happens is an electronic failure. A hard drive is connected to a circuit board on the bottom of your computer. The board is basically the brains of the drive, and it is where the computer interfaces to the hard drive. An electrical failure can occur unexpectedly at any time. Even brand new hard drives are not totally immune to having electrical failures.
Symptoms of an unhealthy hard drive are:
The thing to remember is if you ever hear a loud whining, a grinding noise, or even high-pitched screeches; BACK UP YOUR DATA IMMEDIATELY, because your hard drive may be going bad.
Remember a hard drive is mechanical just like a car. It will break down at some point. It's NOT IF my hard drive will break down , it is WHEN will my hard drive break down.
