Hard disk is a permanent storage device for storing electronic data on a magnetic surface. Hard disk was invented by Reynold Johnson which was capable of storing five million characters. Now-a-days hard disk capacity has increased tremendously with storage capacity of 1 Terabytes. As storage capacity has increased so chances of losing such a huge amount of data form the hard disk.
Hard disk failure can when there is a break down of the hard drive (termed as physical failure of the hard disk) and data stored on the disk cannot be accessed. There are various kind of failure which our hard disk suffer the most common is "Head Crash". Head of the drive is an important component which is used to read and write the information from the hard disk. Head just moves over platter only at a distance of micrometer. Any sort of collision results in severe data loss. If we try to do the recovery by our own can result in further damage of the data.
There are numerous factors which causes hard disk failure. The 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. Hard disk failure is increasing higher, as to increase the speed or read/write operation we are rotating the hard drive with great speed. If any thing goes wrong with the normal operation of hard disk causes severe damage.
There are several techniques used by data recovery experts to recover the data from the failed hard disk. It is done by moving the hard disk to working system. Hard disk is open to replace the parts like head of the drive, arm and chips and sometimes change of platter is also done to make it working such that data recovery can be done on failed hard disk. Hard disk recovery requires clean and dust free environment such as Class 100 Clean Room
Apart from the physical failure of the drive, if our hard disk has suffered a logical crash then in this case data recovery software is helpful. Logical crash can be termed as inability to access the data from hard drive or data lost due to accidental format, viruses or software malfunction or even sabotage.
In case of recovery of data from severely damaged hard disk you should consult data Recovery Company for saving your important data which is trapped inside the failed hard disk.

RAID Data Recovery | Hard Drive Recovery
Data recovery from RAID systems and Hard Disks: Recovery of data from a RAID configuration can be a lot trickier than recovery from stand alone hard disks. RAID 0 and RAID 1 used together (RAID 0 + 1) and RAID 5 offer the best levels of protection. Of course with the simplest form of fault tolerance i.e. RAID 1 the second hard disk mirrors what's on the first one and should one of the hard disks go faulty the other one will seamlessly take over. In RAID 0 of course there is double the chance of losing your data. You need only one of the hard disks to go faulty and you won't be able to boot into your operating system.
However, there may be occasions when you need a specialist data recovery service. Instances are when the power to your hard disk has failed and you are unable to get it to spin. Unless you have an exact copy of that hard disk and are willing to roll your sleeves up and swap power units/motors on the drives and willing to take the chance of not mucking it up you would probably want to get a specialist in. Specialists will also often be able to recover data from
* file servers
* storage area networks
* application servers
* all manner of RAID, from RAID 0 to RAID 10
* web servers
* network attached storage
But data recovery doesn't of course only become necessary when there is a hardware fault. You could have deleted data, erased a file, or cleaned out your old emails. It's surprising what can actually be recovered from your hard disk or RAID array.
When choosing a RAID Data Recovery firm do choose one that offers a money back guarantee or, even better, a guarantee that you will not be charged if they aren't able to recover your data. Some data recovery companies also offer a free trial software that you can download and use to test your RAID array to see if there is any possibility of recovering data.

Harddisk recovery
If you have been using a computer for sometime, inevitably there will become a time when something terrible happens to your PC, usually when you least expect it, but also when you could most do without it! You know the times I'm talking about, you've just finished that 5000 page document in word, and remembered that you have forgotten to 'Save' since about word 2500. No problem, you go to save the document but just before you make the command, BANG, a wierd flash on the screen and then the computer resets itself! But then it won't boot up! Along with panic, bad language and the frantic pressing of that on/off switch, you come to the slow realization that your hard disk may be fried!
If you haven't yet experienced this then I am happy for you, but I also feel slightly sorry for you in as far as you have still got that sudden feeling of desperation and misery to come!
However, take heart, if this unfortunate event does happen to find it's way into your life, all is not lost. This is when you need to find out about hard disk recovery.
Hard Disk Recovery
The most important thing you must remember when you have lost your precious information is NOT to write anything more to the damaged hard disk. This is absolutely paramount. The reason for this is that whenever you delete a file to your recycling bin and even if you empty it, it is not actually deleted from your hard drive. What actaually happens is that the operating system just marks it as having been 'deleted'. Then when a new file is written to the hard disk, the operating system happily overwrites the files marked 'deleted'.
Now you can see why many people have got into trouble for downloading things they shouldn't have, and then erased them to the recycle bin. Later the prohibited material has then been found on their hard disk as it has not yet been overwritten by any new files. Be warned!
OK, back to hard disk recovery. Obviously once your important files have been overwritten by new files you're in big trouble, so just to reiterate, do not write any new files to the affected hard disk.
Very often with a fried hard disk you will not even be able to boot into the operating system, so the next stage of hard disk recovery, would be to remove the disk and transfer it to another computer, preferably with the same operating system or newer, as that which was on the damaged disk. This has a number of advantages in as far as firstly you cannot accidentally write any more to the disk, and also there will be a good possibility of being able to recover files by using the operating system from the host computer.
Although there are many variables and different reasons for data loss, there are also many different methods for hard disk recovery. Sometimes it is quite feasable to use hard disk recovery software on the damaged system but this obviously depends whether it is bootable or not.
All said and done invariably the hard disk recovery process will involve using another operating system to access the files on the damaged disk. If another computer with a compatible operating system is not available, another solution would be to install a new hard disk on to the original machine and put another operating system on to this. It is quite feasable then with a combination of the file manager and windows explorer that the files from the damaged disk can be recovered.
Unfortunately life is rarely so simple, and you may well find that the problem is even more serious than first thought! What next I can hear you scream? Well this is when you will need that hard disk recovery software. Now there is plenty of software out there and some of it quite expensive. You can't really blame the developers as they know they will have desperate customers who will pay top dollar to get 'all those photos' back! However there are still a few freebies out there and one that s well worth trying is <a href="http://www.pcinspector.de/file_recovery/uk/welcome.htm">PC Inspector File Recovery</a>. Now it's not perfect by any means which can be said about all the hard disk recovery software out there, but it's a great starting point. Of course the 'free' price tag should make it that much more appealing!
To use it, you need to install it on the host machine or the new hard drive with a seperate working copy of Windows. You must never install it onto the damaged hard disk. Once it has been installed, let the application run and follow all the steps which are easily followed in the included tutorial guide.
Hopefully this hard disk recovery software will do the job but if not that is when you may have to make that horrible decision of whether to buy more expensive software or take the plunge and pay a specialist service to doit for you. If you decide on the latter, you will have a very good possibility of getting your data back but very often at a very high price.
As for me, I would try and exhaust all the free and cheap possibilities first. That said, if you have no idea of the back or the front of the computer then maybe you could end up doing more damage by 'dabbling' than paying someone to sort it out in the first place!

The Ins And Outs Of Data recovery
Your computer has crashed (again), taking all of your important files with it (again), and you've (finally) gotten smart and started looking into computer data recovery services and options. From NTFS disk recovery to software programs that you can buy to ones that are already installed on your computer and services that specialize in that sort of thing, there are many options for you to protect those vital files, or at least get them back should the horrible but very possible occur.
Most new computers these days come with a recovery program already installed or come with a recovery CD in the package. This is found in a backup feature that is performed either automatically or manually through Windows. The detail with this option is that you're assuming that your computer hasn't been completely destroyed through one incident or another. If it has been, then your information has gone with it, backed up or otherwise, if the backup is stored on the hard drive itself. Fortunately, most of these backup programs also come with an option to burn those backed-up files to a CD or other device, so they're safe from the ravages of whatever might kill your computer's hard drive.
You can use a CD for data recovery in another sense that you can manually take all of your important files and burn them onto a CD. This is nice and easy, but you can't always be sure that you've gotten all of the important stuff. Yes, you may have all of your documents and other important files, but what about things that you may not be aware of? For example, some people may not know of the existence or importance of drivers. If your computer crashes, all of your devices (modem, printer, mouse, and so on) are usually still all right. However, drivers are what ran them. If you had to wipe out your computer and reinstall your operating system from a separate disk, odds are that it won't have the right drivers for the brand or type of devices you have attached to your computer. It's important, for ease of getting your computer back to running order, to back up these drivers as well. Many of the software programs will make sure these, as well as other hidden yet vital files, are protected as well.
Then there are the services. Towing and recovery, hard disk recovery, they all basically do the same thing. In most cases they can't fix your computer if it's been fried by a fatal error or killer virus. However, they have nice equipment and tricks of the trade that they can use in the recovery of your login information, business files, that senior thesis you've been working on for the past year and a half, even frivolous things. They can generally, through lots of work, recover anything you want from your computer and transfer it to another (functional) storage device. This can be very costly, up to hundreds of dollars, but if the files lost were important enough, this might be an option that you would consider.
