The World of Data Recovery
In our day and age, nothing is more valuable than information. Whether it be your own personal information, or corporate information, there is a need to store and protect all the data that we use in our home and business lives. Thankfully with the advent of computers and other advanced technology, storing all of your information is easy, safe, and generally, quite reliable. We can put our data on CDs, flash drives, hard drives, and back it up so that we will never lose it – at least, that was the plan. The problem with our reliance on technology is that sometimes, despite all of our best efforts, it lets us down. We have all experienced the agony of losing something important, be it photographs or documents. This is frustrating and potentially devastating financially, but thanks to developments in the world of data recovery, you can salvage that information that you thought was lost. This article looks at various ways of retrieving lost data, even when you have lost all hope.
Data recovery techniques
Before you can understand how to retrieve lost data, you need to develop an understanding of how it was lost. The first way in which data can be lost is through physical damage of the data medium – think fires, power surges, scratches and so on. Obviously in cases of total destruction there is nothing that can be done here – but there is a lot of data that can be recovered even in this kind of situation. The second common problem is that the technology we use to transport and store data, like flash drives and external hard drives, does not want to co-operate with our computer system. More often than not the host computer does not recognize the foreign media. And lastly, there is the situation where data is accidentally or inadvertently erases, but it does not get lost forever and can indeed be salvaged.
Now that we understand the problem, let’s take a look at the solution.
There are a number of ways in which data can be salvaged from damaged or corrupted sources. They can be loosely divided into physical component repair, and more complex rescuing of the data through software designed for this process. Whichever option is necessary it is crucial that you always consult an expert because these procedures require expert knowledge.
In cases where there is physical damage to the storage system, a number of methods are used to attempt to salvage that which has been lost. There are some parts that can be replaced (particularly in hard drives) after damage, and while the technology is unlikely to function in the same way, experts can still extract information and then slowly analyse what is left to be saved. Think of it like removing an organ from the body – after the procedure the body may not be the same, but there is enough similarity to work with.
Software retrieval is also very popular. Unlike the above method which involved replacing a part of the machine and extracting what you can, data recovery through software involves programs that are designed specifically to access damaged memory. Every time you save something, it creates a kind of receipt, a carbon copy that is a duplicate of the original. Even when your system has been corrupted, these carbon copies remain, and with the right program, they may be accessible.
Either option involves you travelling to a technician or expert, but the latter process is now possible online, which saves you effort and money. Again, this is possible because of memory function.
