How Expensive is Data Recovery?

The recovery of any form of storage device depends on the following:
The value of information held in the disk drive. Confidential information, information concerning clients in a banking system or data holding information of patients in a hospital can be very important. On loosing such information, normally the first thing you would do is to try and recover the data. Loosing banking data can cause a lot of panic and even speculation of fraud. During such moments the most important thing is how to get back the data in the shortest time possible.
Such disk drives would require an emergency data recovery process. Emergency data recovery process is where an expert is assigned to your drive to use all possible methods known and recover the data in the shortest time possible. This may take half the time of a normal data recovery process. Owing to the fact that the recovery process would take less time and more technical concentration the cost of the recovery process would be slightly higher than the normal price.
The extents of the disk damage:
Disk drives suffer different forms of damages, it may be damaged from dropping where the magnetic platter may suffer cracks or the heads may dislocate in such away that this causes a clicking sound when reading the plates of the drive. Damage may be caused by a power surge that may blow all the chips on the printed circuit board of the disk.
The form of repair will differ as the more the damage on the disk drive the more costly it will be to recover the data.
Time required in recovering the data:
The recovery process is charged by mega bytes, data recovery companies have different charging rates depending on the methods and software they use to reconstruct data. A company may be charging 80 $ per mega byte recovered.
As more recovery companies emerge, data recovery companies in India and Africa offer cheap data recovery rates owing to the fact that the industry offers cheap labour
