Article > Hard Disk Failure and Data Recovery

Hard disks fail. And they fail due to many reasons. But, every failure leads to one common result - loss of data!

Hard Disk Failure

  •  A computer user may suddenly discover that the computer is not able to recognise the spinning of the hard disk.
  • At other times, the computer recognises the hard disk spin but the system hangs repeatedly. Such failure of the hard disk is due to the failure of the software code that is embedded in the physical hard drive hardware.
  • Computers might also develop software problems. When the computer is powered on, there is a sudden surge of power that affects the controller board. This electronic damage is indicated when the hard disk does not spin.
  • Internal components of the hard disk might fail. Hard drive then makes a ticking noise.
  • A fall, fire and water too have a damaging effect on the hard drive.
  • When an invalid entry is made on the File Allocation Table (FAT) the user is denied access to the data. This is a logical error. There is no physical damage to the disk. The only problem is that the information on FAT is wrong. Data lost due to logical failure can be recovered. The success rate of data recovery in such cases is high but expensive in terms of time consumed.

 
Data Recovery

Data can be lost due to any of the problems mentioned above. Recovering data that cannot be normally accessed is termed ‘data recovery.’

Data Recovery is a possibility subject to the nature and extent of damage. Normally, majority of the data lost can be retrieved.  Even if there is a major hard disk crash, only a small portion of the disk is damaged by the read/ write head.

How is Data Recovered?

Individuals can recover lost data by installing data recovery software package. The step-by-step procedure given by the company has to be carefully followed:

  • Nothing should be written on the drive from which data has to be recovered. The new data might get entered on the inaccessible old one, as it is no longer protected by OS.
  • Next, a recovery computer must be set up. The problem drive should be attached to this computer as a slave drive.
  • The software recovery program must be installed on the recovery computer. This helps the retrieval of lost files.
  • The retrieved lost data should be copied onto the main drive of the recovery computer.
  • Retrieved files should never be copied on the problem drive.  Data gets lost beyond retrieval if it is done so.
