Physical Data Recovery

Data recovery process leading to recovery or salvaging of data from physically crashed or damaged hard drive is known as the recovery of physical data. When there is physical damage to the hard drive, need for Physics is data recovery. Physical data recovery is the extraction of raw data from a damaged disc. If a hard drive is not accessible by software as the system BIOS, Windows Disk Management, or other disk utilities that can be considered as truly dead and in need of recovery of physical data.

Physical damage always causes at least some data loss, and in many cases the logical structures of the file system are damaged as well. A wide variety of failures can cause physical damage to storage media. CD-ROMs can have their metallic substrate or dye layer scratched off; hard disks can suffer any of the mechanical failures, such as accidents and no engines, and the tapes can simply break.

Physical data recovery is essential when there is a physical problem with the media or plastic that prevents data from being read normally. This type of recovery may include dealing with issues such as the deterioration of magnetic coatings, cracked or broken reels / cartridge deposits increased tape edges, twisted or folded tape, stretched or broken tape, etc. This type of recovery includes the capture of data from the media that has been wrongly subjected to adverse conditions such as water, mud or other debris. While these physical problems are often difficult to manage the recovery of these types can be made in the high 98 + percent.

The chances of successful data recovery depends on the extent of the damage. Data recovery from a plate that has been heated to Curie temperature (770 degrees Celsius for iron) is not even theoretically possible, since the temperature completely demagnetizes dishes. Physical data recovery from a unit that has not mechanically may not need any logical reconstruction if it can be repaired successfully, although in practice many physical repairs followed by logical reconstruction of some details, if due to loss Final of the damaged surfaces of the disc.

Most physical damage can not be repaired by end users. Some physical recoveries are long and can be expensive. In most cases the recoveries of physical data offer excellent chances of success of data recovery. In addition, end users generally do not have the hardware or technical knowledge needed to make these repairs, therefore, data recovery companies consulted. These firms often use Class 100 clean facilities to protect the media while repairs are being made. Different experts in recovering data provide different rates of recovery.

The physical damage can be caused due to:

* Moisture contact or penetration

* Exposure to extreme temperatures

* Variations in humidity

* Impact force and sustained

* Defective mechanical or electronic

* Spike / increasing the power supply

Degrading * read / write heads

Some of the procedures for recovering physical data are:

* Removing a damaged PCB (printed circuit board) and its replacement with a matching PCB from a healthy boost

* Changing the original damaged read / write head assembly with matching parts of a healthy drive, removing the hard disk platters from the original damaged drive and installing a healthy

* Removing the hard disk platters from the original damaged drive and installing a healthy

Try to solve the problem yourself is more controversial as it may cause physical damage in the process.

The average number of failures in physical recovery time is from 5 to 10 business days. In rare circumstances, not to take more time to recover the data, especially if there is extensive damage to the plates and / or components we asked the hard to find. The recovery time usually depends on three variables:

* What type of fault has occurred?

* What is the extent of the damage?

* Requires special order of the components?

Prices vary widely from service to service. Physical data recovery is a very sophisticated and often expensive, service.
