The Truth about Data Recovery

June 6th, 2011

The Truth about Data RecoveryComputers can, without a doubt, be complicated beasts; one minute they are doing exactly what you want them to do, and the next they are suddenly going off and doing their own thing.  And before you know it, your computer crashes, leaving you with missing files, an increased heart rate and a bad temper.  But before you’re ready to throw your computer out the window in anger, let’s take a few deep breathes and talk about what actually happens when a file accidentally deleted and explore possible ways of getting that information back again.

For starters, when you unintentionally delete a file and begin to have a panic attack once the file has disappeared, you can rest assured that your file is not lost forever (phew!). The file will not be immediately visible in the directory or folder that you (or the computer) thought you stored it in. Instead, the file gets re-named so that the path it was using can be overwritten and can then be found in a hidden index file. The good news is, it can be completely recovered from this file if needed. In fact, all data continues to be stored on your computer until it is completely overwritten. And just to clear something up, by overwritten, I do not mean different information. It takes a random mix of binary code (0 and 1) to completely obliterate a data or file’s information. This is why hard drives should be absolutely and completely destroyed to an unrecognizable pulp or at least be overwritten by using a program that exists to overwrite data. Do not just recycle your computer or sell it to someone else without getting rid of your data properly first, or you could come to regret it later. This is especially important if you have sensitive information or media on the computer!

So now that we have established that data recovery is possible, how is it done? Well, there are a number of cleverly devised free and paid versions of data recovery programs available, depending on what your data recovering needs are. For example, you may have just accidentally deleted a file. Recovering this is relatively simple when compared to trying to recover data from a damaged or corrupted file. Not only can you retrieve the data but you can also use the software to recover other types of deleted information such as emails or email attachments.

Some paid data recovery programs have a “no recovery – no fee” guarantee.  This may seem like a pretty high guarantee to offer, but if self-recovery or the free programs aren’t giving you the results you need, the paid programs might be better route to take.  Furthermore, the free programs may have a smaller range of capabilities; how/why your data was lost in to begin with will likely determine how it can be recovered. No matter how you lost your data and how hopeless you think the situation may be in returning that data to your computer, fear not. There are data recovery experts available to help you no matter how severe your data loss may (seem to) be!
