Hard drive of the computer system is the most essential part which is used to store data. At present hard drive can store more than 100 of Gigabytes of data and it will increase to Terabytes. Data storing has become relatively very easy as compared to olden day. At the beginning of the computer system there was no mechanism of saving but it changes with time and technology. At that time hard drive requires large space and store a very little amount of data.



Now the size of the hard drive has relatively reduced to 0.85 inch, store about 8 GB of data and weight only 2 grams. Although larger capacity of hard drive has been announced this is going to store more than 1 Tera Byte of data. As the capacity of hard drive is growing so are the chances of data loss and at the same time recovering data from such drive is a challenge.

Data loss from hard drive can occur either because of logical failure or due to physical failure. Recovering the data from such failure is termed as ‘Data Recovery". Logical failure can occur due to formatting of the hard drive, or due to software malfunction, viruses, file/directory deletion, file-system corruption and in some cases electro static discharge. Data recovery from logical failures can be done by using data recovery software. In some cases data on the hard drive becomes inaccessible and whenever we try to access that partition of hard drive an error message flash “Drive is not formatted. Do you want to format the drive?" Stellar Phoenix Windows Data Recovery Software provides recovering from all such type of cases.

Another type of failure is physical failure. There are basically two types of physical failure, mechanical and electronic. Mechanical failure occur mainly due to spindle motor and head crash, Due to excessive heat from bearing, Spindle motor failure occur. The increased heats resulting from the bearing failure expands the drive shaft and therefore seizes the spindle motor. This causes the drive becomes inoperative. Most of the time we get a warning that something bad is about to happen. We hear a loud whining, a grinding before hard drive dies. Another physical failure occurs due to electronic failure. At the bottom of the hard drive there is an electronic circuit board. This is basically the brain of the hard drive which provides interface to the computer and hard drive. Due to the short circuit or power surge some circuit get damaged and results in the physical failure which can revert by replacing the circuit.

We make sure that we always back up our data so that we avoid the miss happening of data loss. In any case if the data loss has occurred then there is plenty of data recovery & disk recovery software available online which will helps us to retrieve our data.
