Data recovery

Technology has brought so many advantages to our lives. So many things have been computerized and digitized. One shortcoming of computerized gadgets and machines can be vandalism or break down and lose vital data. The solution is here with us. Technology now offers us data recovery options that are fast and reliable in recovering lost data. Most of the data recovery companies now have the best tools and software for this job hence time saving. These companies are   not only good at this job but also cost effective. This new data recovery methods have been made to help forensics in recovering data and other related problems. The tools used in these companies are specifically made to tackle the exact problem as it is.

We’ve all dealt with data loss, whether it was from a hard drive failure, data corruption or accidentally deleting a file. If you’ve ever experienced a major loss of data, you’ve probably wondered about data recovery. Data loss can take many forms — accidental deletion, hard drive failure, software bugs, data corruption, hacking, even a simple power failure can cause you to lose data. And, of course, there are more extreme cases, like when a hard drive is recovered from a plane crash; amazingly, some data recovery specialists can retrieve data from storage media that’s been almost completely destroyed.

If a piece of data used to be on your hard drive, solid-state drive, USB stick, RAID, or other storage media, you might be able to hire someone (or purchase some software) to perform data recovery. Data recovery is, simply, the salvaging and repair of data that has been lost. Of course, data recovery won’t always be possible; sometimes a system can be too corrupted or damaged to get much of the data back. However, data-recovery technology has become extremely advanced; for example, Kroll Ontrack, an Australian data recovery company, was able to recover 99% of the data from a hard drive that was on the Challenger space craft when it disintegrated upon re-entry.

Data recovery solutions has been customized to be relevant and helpful in tackling the needs of various business ventures, security systems, government and disciplinary forces, learning institutions and other entities. Today companies have been experiencing insecurities like outsiders hacking or viruses in their software.

Remember the days when chkdsk and Norton Disk Doctor were the only things you could count on when recovering a broken file system? Things have changed. Today, you have a choice of hundreds of different tools offering to recover your hard drive, fix broken partitions and repair the file system. And of course, there are tools to salvage your data. With so many different tools around, which one will you choose? In order to make an informed decision, you have to know a little about what’s inside. Many data recovery technologies today were not available two years before. In addition, some of those technologies are implemented in most products, while others are strictly proprietary and come in select tools only.

The first and most important technology that revolutionized the data recovery marked was signature-search. Implemented in one way or another in most pro-grade data recovery tools, the technology ensures that you can get your data back even if the entire file system is wiped off completely from the hard drive, flash stick or memory card you are about to recover. Before this technology was invented, so-called ‘undelete’ tools were available to let computer users recover deleted files by undoing the delete operation. Quite simply, these tools unmarked the ‘deleted’ attribute in the file system, giving the user access to the original file as if it was never deleted in the first place. Sounds too simple to be true? In fact, this approach worked quite well for single, freshly deleted files. Needless to say, if you had more than one deleted file, or deleted them a few hours ago, or the filesystem was corrupted, these undelete tools would mess up your hard drive instead of restoring your data.
