Data recovery techniques are deployed in situations where data on your hard drive becomes corrupt or inaccessible. There is not just one way to recover data that has been lost due to formatting, malicious programs or accidental deletions. If you are planning to repair the physical damages by yourself, know that you will forfeit all guarantees of the manufacturer. Logical damages are caused by corrupt programs or Operating System failure. Physical damage related data loss cases are fewer in number. It is wise to seek help from a reputed data recovery company to repair physical damage.
Power outage, device failure, and computer crash are the most common reasons for data loss on your computer. Most common method of data recovery is to check for the consistency of the drive’s physical specification and its logical structure. A mismatch is a sure-shot way to lose data temporarily or even permanently. Consistency checking finds out the illogical and inconsistent directory links and lists them for correction. In most cases, corrections are done automatically.
When data on your computer is deleted by pressing a few keys, it becomes inaccessible once you remove it from Recycle Bin. Until you copy new data to your hard drive, deleted items are still intact. Data carving is the technique used to recover data with no information about their location on the hard disk. You simply remove the pointers to the item when you delete it. An expert can find the location, size, and contents of this item. This technique is very promising, but it requires sufficient time and energy from the expert.
Data recovery becomes a tough task when you to work on a running system. A minimal operating system can be used in such cases. Such an operating system is capable of running specific repair packages. Create an exact copy of all data on your hard drive using imaging tools and separate it from the system.
