Hard Disk Failure And Its Possible Causes

As we all know hard disk is used to store data. It is non volatile storage device that can store huge of data. Now a days a normal hard disk can store approx 1 tera bytes of data. But have you ever even imagined that if it can store this much amount of huge data. If it get failed due to any reason, how big loss it will be?

Hard disk failure occur mainly when hard drive malfunctions and the data stored in the hard drive become inaccessible. There are various reasons because of which hard disk fails to work. Among them Head Crash is most common. Head is one of the most important part of Hard disk and it is used to perform read/write operation. As head moves over platter at distance of just few micrometer any sort of collission can create severe problem. Sometimes people try to do recovery by there own but they don't know that by doing this they are reducing the possibility of data recovery .

There are several factors which become reason of hard disk failure . The most common are power surges, voltage fluctuations, electronic malfunction, physical shock, corrosion, exposure to high magnetic waves, sharp impact, high temperature exposure etc. To increase the capacity of hard disk to read/write data it is important to rotate head with more speed .But if head fails to cope up with high speed then severe damage can happen which result in to data loss.

But thanks to advance technologies data recovery services are available that can recover our data with full confidentiality .Various Techniques are used by hard drive recover experts to recover data. Most importantly all recovery process is carried out in Class 100 Clean Room. Class 100 clean room has its own importance in data recovery process .As whole data recovery process is very crucial it is carried out in controlled environment of clean room. Otherwise data get damaged.

Stellar Information Systems Ltd. is a data recovery company which is offering laptop hard drive recovery services from decades . With its skilled technicians,class 100 clean room ,advanced recovery tools it is providing best data recovery services to its customer. To explore more visit http://www.stellarinfo.co.in/ 

Hard Disk Failure Is Not The End

Hard disk is a very complex hardware piece ,combination of circuit board , platter ,media head assembler and spindle motor. But when things not work accordingly then hard disk failure occur. And it is very important to find out what the actual problem is before attempting hard drive recovery.

Major Components in hard disk:

The Platters: Platters are actual disk which has magnetic coating in it. It is made of aluminum alloy and it is the actual part where data get stored.

The Spindle Motor: The other most important component upon which platter is mounted is spindle motor .Spindle motor rotates platter at constant Revolution Per Minute ranging from 3,600 to 7200 RPM .

The Read/Write Heads: Read/Write head read and write data to the platters .It is most crucial component present in the hard drive. When platter spin it creates pressure which lifts the head and the gap between head and platter is so minute that even a small dust particle can do severe damage.

The Head Actuators: All the heads available in the hard drive are attached to actuator. It is only the actuator which moves the head over the platter .

If above mentioned any device does not work properly then it can become one of the reason for hard disk failure. We can classify hard disk failure into two types:

Logical failure: This type of problem comes into existence when file system has some issues. Like when hard drive is properly working but because of some reasons files are not accessible. It can be due to deletion of files accidentally or intentionally or because of virus attack.

Physical failure: This type of problem arises when hard drive does not spin properly ,unable to read and creates noise. Spinning disk available in the hard disk sometimes creates problem because of which hard disk does not able to spin properly. During this condition user will hear harsh noise instead of normal noise. A user should listen hard disk properly to recognize the problem .Any abnormal noise means that there is some problem in hard disk and it requires hard disk recovery service to get back in normal working state.

This type of cases require hard disk recovery services.Hard drive recovery is carried out in class 100 clean room in which temperature is maintained and the environment is kept free from dust. Class 100 clean room is important because during the transplantation of head. Experts take new hard disk of same parameter and then transplant the new head and align it properly. Here alignment means maintaining the gap of .5 microns between head and platter for read and write .

Stellar Information Systems Limited is the data recovery company which is providing its best in data recovery services in various places. And gained in numerous satisfied customers with its specialized technicians , Class 100 Clean Room and advanced Recovery tools.You can avail Stellar's cost-effective, reliable and safe services from 12 locations in India : Ahmedabad, Bangalore, Chandigarh, Chennai, Delhi, Gurgaon, Hyderabad, Kolkata, Mumbai, Noida, Pune and Vashi.

Need of Data Recovery Services

As now a days Computers, laptops and storage devices are like part of our day to day activity. From morning to evening we are surrounded with these electronics devices. Sometimes while working very weird type of situation arises which makes us helpless , when we lost our whole data and no backup in our hand at that time of situation we regret why didn’t we maintained backup. But by regretting we can not bring back our data. At time we should not loose our temper and behave calmly. First of all we should analyze the reason of data loss. It can be due to many reasons mainly divided in two major categories-

1. Logical Failure : Logical failure includes accidental deletion of files, virus attack, formatting, sabotage, system error and so on.
   

2. Physical Failure : Physical failure mainly includes natural disaster like flood, fire, earth quake etc.

To identify the cause of the data loss is most important because by identifying you can calculate how serious the case is. Sometimes people try to recover their data by themselves but they don’t know by doing this they are reducing the possibility of data recovery.

Data recovery companies are available that are sufficient in recovering your precious data. They will firstly inspect the corrupted device and then take appropriate step. Data is recovered with the help of exclusive tools and software’s by data recovery specialist in protected environment of Class 100 Clean room.

Stellar data recovery is one of the trusted data recovery companies that is delivering its services to its customers from last 17 years. It can recover data from RAID servers, NAS, SAN, hard disk drives and other storage devices.
