Types of Hard Drive Failure
We will be discussing data recovery in this article we will mainly focus on issues about hard drive failures as these types of failures are most common. There are two primary forms of failure in a hard drive, physical and logical. Logical failures are often a result of file-system corruption.
This can occur due to a virus infection, accidentally deletion of important system files or registry files, and in some cases electro-static discharge may cause the failure. In most cases where a logical failure has occurred, the hard drive is still recognized by the system BIOS, but it will not boot as usual. In most cases, your data should still be intact on the drive, though it may appear to be inaccessible.
If the BIOS do not detect the presence of the hard disk, then chances are that physical failure has occurred. Physical failures may happen due to wide variety of causes. There are two sub-categories for physical hard disk failures, electronic and mechanical. Mechanical failures usually happen with spindle motor failure. Spindle motor failure can result from over heat due to a bearing failure. The excessive heat resulting from the bearing failure will expand the drive shaft and eventually seize the spindle motor. Instantly your drive will become inoperative.
Occasionally, you will get an early warning that something bad is about to happen. You may hear a loud beep, a grinding noise, and even high-pitched screeches like laser gun sound. If anything like this starts to occur, data must be backed up immediately.
Another physical problem is that sometimes head gets an electronic failure. If you look at a hard drive you will notice a circuit board right on the bottom.
This circuit board is basically the brains of the drive, and it is where the Computer interfaces to the hard disk. An electrical failure can occur unexpectedly. Even new hard drives are not totally immune to having sudden electrical failures. Often it's just a faulty component, sometimes its improper installation. It's important to also keep your system clean and well ventilated all the time, since excessive heat can damage the electrical components on the hard drive. If you have a system that is placed in a somewhat contained area, you may add an additional 80mm fan to cool the internal components of the system, especially the hard drive. No other component of a computer works as much as the hard disk, and therefore it is extremely important not to over-look it when cooling issues arise.
when you have a hard drive failure do not handle it yourself, immediately call the professional Data recovery company, that is the only and the best option.
