Our dependence on digital devices and data for information, both at the personal and the professional levels has increased manifolds. Our cherished moments are all stored on our devices. Businesses today rely heavily on the information contained in the data that provide them an edge over their competitors. It, therefore, becomes obvious that the devices hold a significant position in our lives. It is our responsibility to secure the data stored as once the device fails; one may be under a lot of trouble and anxiety.
Types of data losses
Since it all depends on the devices one stores data in, one has to rely on how the device is functioning. It is inevitable that the digital device you are using fails at some point of time or the other. The reasons for failure may be many, but the types of device failures, which lead to data loss, have basically been characterized into two types: Logical failures and physical failures. Data loss due to logical failures is the most commonly encountered. Data loss in these cases occurs due to the hard drive or any other drive not being able to access data that is present. This may either be due to a power surge or a virus attack or accidental deletion. Physical failures comprise failure of your storage devices due to electronic or mechanical failure due to physical damage.
Can the data be salvaged?
Once your device fails, the first thing, which comes to mind, is the scary feeling of losing your data. But it may not always be the case. There are chances that the data may be retrieved, but it is not an easy and totally reliable task. It will depend largely on the type of device failure and the extent of it. If the device has failed owing to a logical failure, chances are your data may be salvaged. In the case of physical failure, professional agencies come to the rescue but there is no surety as to whether the data may be salvaged or not.
Why is salvaging the data difficult?
Once your device has failed, the process of data retrieval starts. The first thing is to identify the mode of failure. Once you have done so, make sure you don’t go about saving any new data to avoid data overwriting. In the case of logical data recovery, one may go about attempting to salvage data through a number of freeware available but it is not always that easy. You may be able to retrieve only a part of your data or none of it. The final resort would be seeking the help of professional data retrievers, which is again expensive and may take a number of days depending on the volume of data and extent of damage.
In the case of physical failures, the process is even more complex. In the case of hard drives or tapes or other devices, one shouldn’t go about fixing the hardware problems oneself unless one is really sure. The data retrieval on tapes, for example, is performed in a dust-free environment, maintaining which is again not easy. The damage may be large leading to a lot of difficulties as well. Professional agencies do come to the fore with their expertise, but sometimes the damage may render the device inaccessible, and even they can’t help.
So stay smart in backing-up data, as you are while creating them.
