There is a lot of dependence on data in this technology savvy world. Both our personal memories and professional data are recorded and stored digitally. Even companies rely largely on how effectively data is utilized and how well the information is derived out of it. But certain complications do arise when the storage device suffers some problems, and all your data is at risk.One needs to be careful regarding how well your data has been secured so that the information isn’t lost along with the data.

How can data be lost?

The data stored on your hard drive may get lost due to a number of reasons: you may delete the data accidentally, the system may crash or the drive may get corrupted leading to loss of data. There can basically be two types of failure due to which data is lost:

  1. Logical failure
  2. Physical failure

Most of the data that is lost is due to logical failure rather than physical failure. Logical failures are mainly caused due to the user errors or due to virus attacks as a result of which the drives turn corrupt. Some of the logical failures may also be due to the bad sectors which develop in the hard drives.


Physical failures mainly deal with the physical and electronic failure of the drive. Physical damage to the drive or excessive wear may lead to physical failure. Recovery of data in case of physical failures is generally the most expensive.

Types of data recovery

Since the hard drive failure can be attributable mainly to two factors, physical and logical, the types of data recovery are also characterized into logical data recovery and physical data recovery. The case of logical data recovery arises when data has been lost, accidentally or the drive was mistakenly formatted or the operating system turned corrupt. Physical data recovery would involve rebuilding the drive physically which involves a lot of costs and expertise and is generally not performed by people on their own.

Who can perform logical data recovery?

Logical data recovery generally deals with rebuilding files and folders infected either by virus attacks or by user inflicted errors: accidental deletion or formatting. Also, logical data recovery doesn’t need the expertise and care required for physical data recovery. Therefore, anyone can initiate data recovery methods. There are various options available while retrieving logical data. Once the data has been deleted accidentally, it doesn’t get lost forever. It can be retrieved. To start the retrieval process, one must ensure that no new data is saved onto the hard disk to avoid chances of the deleted data getting over-written. Once this has been ensured, we can avail various data retrieving software packages. There are a series of simple steps which when followed lead to salvaging of data. If the data is important and of strategic importance, it is always advisable to seek help of professional retrieving agencies who have the expertise in data salvaging.
