Best Hard Disk Recovery Tool

It is quite a frustrating moment when you put all their efforts for some project on your computer and then it is all lost.

It is quite unfortunate that after all the hard work, the data that was saved is all lost. One of the factors that lead to loss of data is when your hard drive crash.

However, hard disk recovery tool can come to your aid. Nowadays, most data recovery software are designed to be user-friendly and simple to operate, therefore most users should not have much problems with it.

When it comes to files that have been deleted by mistake or even deliberately they can still be retrieved. You just need to know the procedures to do it.

They are many ways to find free hard drive recovery tools online. Most download directories such as download.com offers hundreds of free data recovery tools. However, some are demo versions and usually requires you to pay a upgrade fee for all functionalities.

However, I find that most paid data recovery tools are better than free ones and the cost is quite affordable, usually under $50.

Most data recovery software have common functions such as retrieving files after a partitioning error or from RAW hard drives, an accidental format, files that have been emptied from the recycle bin, it can even recover photos music videos and emails and can also from cameras USB and so on and so forth.

However do note that, for physical HDD failure such as read/write disk head failure, hard disk platter scratched or crashed, it will require the help of a professional data recovery professional.

In most cases, recovery of the data is not guaranteed and the cost can be quite expensive. Typically, it can run into thousands of dollars.

Therefore, the logical thing to do is to backup your vital data regularly. It can save you money and problems in the long run.

Hard Disk Data Recovery

Data recovery involves salvaging of damaged, failed, corrupted and in any other case unavailable data from a storage media. In hard drive data recovery, the goal is normally to retrieve deleted or corrupted data by either the use of software program or advanced forensic techniques. Hard disks data losses could be brought on by a wide variety of things. It might be that there was a hard disk head crash, damaged logical structures in the file method or malware. For physical harm, technical expertise may well be required to be able to retrieve lost data. On the other hand, exactly where the file method has been damaged, the end user could be able to retrieve the data using specific techniques.

Hard disk data recovery might be done by use of disk imaging. This involves reconstructing the usable data from the already existing sectors. Tools for example HDClone and others are used to either communicating using the hard drive directly thus bypassing the operating process and also the BIOS, by reading even the bad sectors usually skipped by the operating process, by use of several read commands and disabling specific features for instance SMART to minimize imaging time and further drive degradation.

Hard disk data recovery brought on by logical harm could be performed using different programs. Since this sort of dilemma is brought on by power outages exactly where files tend to remain totally unwritten, these inconsistencies might be corrected using application. Sometimes though, the drive may well not be getting sufficient power. An additional possibility is that the firmware may possibly have become unstable. In all on the above scenarios, you don’t require the expertise of a rocket scientist to resolve the dilemma. All you’ve to do is know the correct software program to use and how to go about making it work. It’s even feasible to recover accidental deletion of data. Trust me some powerful application are out there that may do exactly that.

Would it be rather nice instead to prevent harm from the first place than need to go trying to find hard disk data recovery specialists or strategies on the net to recover the report you worked on last month or those vacation pictures you took last year? It’s simpler done than said. Program maintenance tools that come using the operating program may be used to maintain consistencies and protect against bugs inside file method prior to something major occurs. Make regular restore points and backup your data frequently. You never know when your hard disk may just decide it has had adequate of you and refuse to respond to your requests.

Hard Disk Failure and Data Recovery

Hard Disk: An Introduction

Hard disk is a non-volatile data storage device that stores electronic data on a magnetic surface layered onto hard disk platters. Word

“Hard” is use to differentiate it from a soft, or floppy disk. Hard disks hold more data and can store from 10 to more than 100 gigabytes, whereas most floppies have a maximum storage capacity of 1.4 megabytes. Normally term hard disk is much familiar with computers only but it is widely used as network attached storage for large volume storage. Furthermore, appliance of hard disk drives spread out to video recorders, audio players, digital organizers, digital cameras, and even in latest cellular telephones.

Reynold Johnson invented first hard disk in 1955 for IBM 305 computer with 24 inch platters and total capacity of five million characters, and in 1956 – first commercial hard disk was launched with 5 megabyte capacity, the IBM 350 RAMAC disk drive. Within time frame of 50 years and rapid progress in technical enhancement, we have now reached to latest 2006 – First 750 GB hard drive from (Seagate) and First 200 GB 2.5″ Hard Drive utilizing Perpendicular recording (Toshiba).

Hard disk consists four basic components:

The Platters: Platters are the actual disks inside the drive that store the magnetized data. Conventional platters are made of a light aluminum alloy and coated with magnetize-able material but latest technology uses glass or ceramic platters as they are thinner and also heat resisting. Most drives have at least two platters and the larger the storage capacity of the drive, the more platters there are.

The Spindle Motor: Hard disk drive consists of a spindle on which the platters spin at a constant RPM. Moving along and between the platters on a common arm are read-write heads. The platters in a drive are divided by disk spacers and are clamped to a revolving spindle that turns all the platters in a uniform motion. The spindle motor is built right into the spindle and rotates the platters at a constant set rate ranging from 3,600 to 7,200 RPM.

The Read/Write Heads: Read/write heads read and write

data to the platters, and each head is fixed to a single actuator shaft so that

all the heads move in harmony. Typically, only one of the heads is active at a

time either reading or writing data, if not in use, the heads are inactive, but when 

it is in motion the spinning of the platters generate air pressure that lifts the heads off the platters. The space between the platter and the head is so minute that even one dust particle or a fingerprint could disable the spin. When the platters cease spinning the heads come to rest, at a preset position on the heads, called the landing zone.

The Head Actuator: All the heads are attached to a single head actuator arm, which moves the heads around the platters. The

actuator arm moves the heads on an arc across the platters as they spin, allowing each head to access almost the entire surface of the platter. Contemporary hard drives use a voice coil actuator, which controls the movement of a coil toward or away from a permanent magnet based on the amount of current flowing through it.

Fundamental structures of all hard disk are same, and are composed of the same physical features, but their performance depends on the quality of their inner components.

Hard Disk Failure:

Hard Disk Failure occurs when a hard disk drive malfunctions and the accumulate data cannot be accessed. It may happen in the course of normal operation due to an internal or external factor. Disk failure varies and the most common is “Head Crash” where the internal read and write head of a device touches a platter or magnetic storage surface often grinding away the magnetic surface. Head hover just micrometers from the platters plane which makes such collision a common one. This sort of crash usually invites severe data loss and unprofessional data recovery attempts results further damage to the remaining data. Hard drive also includes other controller electronics i.e., semiconductors, valves or electronic circuits, and major components such as Platters, Spindle Motor and Head Actuator. Failure on any of these devices may cause a hard disk failure.

Factors that causes disk failure are numerous, yet most common are power surges, voltage fluctuations, electronic malfunction, physical shock, wear and tear, corrosion, exposure to high magnetic waves, sharp impact, high temperature exposure etc.

The phenomena of hard disk failure is raising higher, as to increase the read and write speed, today we have latest hard disk rotating amazingly faster and this immense revolving speed generates massive centrifugal force, a single adverse cause in the course of normal operation can cause severe hard disk failure.

Hard Disk Data Recovery:

Hard disk data recovery is the process of recovering the trapped data from the damage hard disk device, when it can not be accessed in normal circumstance. Several

techniques are used for retrieving data from damaged disk and techniques vary accordingly. It can be done by moving disk drive to a working CPU, or may have to open the disk drive and replace parts such as read/write heads, arms and chips, and sometime the platters have to be removed and placed into another drive. Physical damage can not be repaired by the general users, as it requires clean and dust free lab environment;

in addition, proper technical expertise. Under microscopic observation, with proper tool and techniques, the damage drive is put on to

test for data salvaging.
