How To Do Data Recovery After Hard Drive Failure


Data is the most important part of any business and if that data is lost for some reason, it is hard to recover. That is why organizations emphasize more importance on hard drive recovery mechanisms.

Data is protected inside computers within a hard disk. A hard disk drive (HDD), also known as a hard drive, is a device used for storing and retrieving digital information, mainly computer (raw) data. Comprising of one or usually two (hard) rapidly rotating disks, also known as platters, with them are attached the magnetic heads, arranged in a manner to write data on the surface.

Over the time, the hard disks have reduced in size and price, though they significantly increased in capacity and speeds. Starting off from just a few hundred MBs (megabyte) of storage, the hard disk of today can store up to 1TB (terabyte) on a single platter, and companies such as WD (Western Digital), Seagate, Samsung, Toshiba and many more have already introduced 2TB hard disks in the market.


Step 1

There are various reason why a hard might fail to work, head crash (when the head makes contact with the rotating platter due to a shock or any other reason. This will cause partial or complete loss of data depending upon the amount of damage done to the platters. Bad Sectors; where some magnetic sectors may become faulty without affecting the rest of the drive. Circuit Failure; where the components of the electronic circuitry may fail causing the device to be inoperable.


Step 2

Hard drive data recovery could sometimes be partial or complete, if the platter’s magnetic coating is not completely destroyed. Companies that are specialized in carrying out data recovery, at significant cost, open the hard disks in a clean room, using required equipment to read the data from the platters that the user usually feels is lost. If there is an electronic glitch, then the electronics board can be replaced, though some older versioned hard drives are incompatible with other circuit boards.


Step 3

Often it so happens, that the hard disk drive can be saved for the times it needs in order to transfer the data to another source. Usually when the drive dies, technicians try to start it once more. As soon as it starts, they try and back-up as much data as they can, because then it would never start again and your hard drive recovery will become almost impossible.


Step 4

Other more crude ways of saving hard drive data were to put the hard disk in the freezer after wrapping it in a water-proof wrapping, to cool it off, or trying to make it work by tapping or rotating the body of the hard disk. This method of hard drive recovery is a bit unorthodox but it can work.

Step 5

You can hire professionals also, they might cost you a little for hard drive recovery process but will ensure you give you peace of mind as well.


Data recovery from hard drives can also be achieved by the help of hard disk data recovery software available in the market. So that the users can themselves be able to retrieve data that has been lost. A hard drive recovery service is usually very costly but by using these software programs that range from $50 to $150, a lot of money can be saved.


But it is highly recommended that if the data on your dead hard drive is very important, it is best if you seek professional help that guarantees 85 to 90% success rate.
