Data Recovery: About it and the four phase cycle of recovery

Data recovery is a process of retrieving or getting back the data that has been removed due to various reasons. Like the ones mentioned above, in a day-to-day life. This could be from corrupted media, drives, or files.

Now, like any other process known, data recovery too is a very logical and methodical process. This essentially has four phases of steps to retrieve the data:

  1. Phase one: Fix the Hard Disk Drive: This phase, as the term itself indicates, is about repairing the hard disk drive of the system or the network. As well known a fact it is that the hard disk can come as a major savior to data prevention, even when a network function fails. Thus, concentrating on the hard disk drive would be but the foundation stone lay to ensure that the lost data can be retrieved. Repairing it means readying it for its optimal and smooth use, without any interruptions and glitches. For example, if the PCB is defective, it is to be made sure that it be either replaced or fixed properly, or the functioning of the heads has to be rechecked and so on.
  2. Phase two: Imaging the drive to a new disk image file/drive: Ensure that the drive that has currently gone dysfunctional be imaged to a fresh drive or even to a new disk image file. As mentioned, that the hard disk is the parent component to the chances of reading the data back. So, in this case, the data should be transferred to a fresh drive to ensure that it can be rescued and reproduced unharmed and unchanged. The faulty drive will be a long term threat to the data to be stored in the future. Create an image of the drive. This would ensure that the data is saved as a second copy on another fresh drive or device. This would most certainly work in getting the lost data back, without any harm or infected changes.
  3. Phase three: Recovery of partitions, Files, MBR and MFT logically: Now that the drive is already metamorphosed to a new look- into an all-new drive, one can begin the formal process of data recovery full on. Using this “photocopy” version of the failed drive, it is possible to now fix the partition table, the MFT, and the MBT. This is important as this would facilitate the retrieval of the data by reading the file system’s data structure.
  4. Phase four: Repair Retrieved Damaged files: As much of a utopia one would hope for- to retrieve the data impeccably untouched, there are quite a many chances of some part of it being damaged or corrupted. Say a part of a file written in a particular part of the drive is corrupted. This is very common to see as the disk drive goes for a toss. Now, the data has to be made readable from its current failing condition. For curing the files of this situation, a world of software is available. So, you are almost there!
