Common Hard Drive Failures

Do you own a computer? If you do, have you ever experienced a crash of your system’s hard drive? I am sure that it is a terrifying and frustrating experience. This is because if the data of the computer cannot be read due to hardware problem then the computer is of no use to us. Sometimes the operating system might be in working condition, but still the data wont be accessible or it might be even damaged. If you have a backup of the data then only you can be safe thinking about restoring your information from a new drive. Another way to get back your data is to make your pocket very light by paying heavy amounts.

Before understanding how a hard drive fails to function, it is important for us to know what exactly a hard drive unit is and its functions. A hard drive is a huge device having magnetic storing media that is encased on some rigid platters. It will allow the drive for storing huge data, which can be written and accessed in no time. It is also a must to know about the different components and functions to have a better picture about the problem when your hard drive fails to work. There are different types of hard drive failures and among them the most common one is head crash. In this head crash type of hard drive failure; the drive head easily manages to damage the system by just touching the platter.

Once this type of damage occurs, it is tough for your drive to get recovered again. There is another type of hard drive failure, which sprouts due to several imperfections present on magnetic media. If the disk sector cant hold properly any magnetic alignment, then the data becomes inaccessible. For this type of failures, lower level of formatting can be done in those small sectors and these regions wont be used to store any data later and thus this might bring some positive results but it’s a very lengthy process and all the data present in these minor sectors is lost. Even the mobile systems used were prone to the platters that got shattered for the sole reason that they were made up of glass and this glass was easily susceptible to shocks hence new materials are being used to overcome this problem.

Hence before you purchase a hard drive, it is necessary that you check out for MTBF rating. This rating will tell you about your hard drive’s life span and will help you to approximate the quality of the product. There are several other things that have come up these days like increase in the size of hard drive to store more information and increase in number of platters that can be helpful in preventing total damage of your hard drives. In spite of all these the major failure of the hard drive depends on the amount of usage of your system ad the way you are handling it. Hence perfection in handling your system will be fruitful for you and will save your system from being damaged.
