1. Hard drives are anything but hard.
2. This is a complex task.
3. One false move can never be corrected.
Many of us know at least one person who tried recovering data from computers crashed. In most cases this "do it yourself" decision follows a quote (perceived) cost from a specialist data recovery services.
The "useful" for a range of suggestions Fix-it-yourself program to hit the hard drive, put it in a freezer, shaking the hard drive, open the hard drive and dust and so on. In a vast majority of cases where users tried to retrieve lost data themselves, it has only created problems that even an expert could not fix and the irreversible loss of data!
Let us refer to a number of reason - a hard drive is tricky tricky tricky! In attempting a hard drive recovery, many people open it and then look at all components. This will almost always result in permanent data loss. The hard drive is full of disk trays, pins, actuator arm, and other delicate components. The disc tray is the most sensitive part of the hard drive and so light that even a single particle of dust could harm him. Therefore recovery specialists data actually work in clean rooms and sterile that can put theater of a hospital to shame! The trays containing the data is made from glass, ceramics, light aluminum alloy. They are then coated with a magnetizable layer. The disk platters are picky about what comes in contact with them and will react negatively to dust, fingerprints and other debris.
These trays are moved by the pin that moves according to the rate determined by a motor. The valuable data held in the folds of the plates is accessible by the arm of the actuator. When the hard drive functions normally, all these elements come together in perfect harmony. So when an untrained hand immersed in the balanced mechanism, it can set in motion all sorts of disturbances that could lead to an irretrievable loss of data.
Take for instance one of the aspects of today's technology hard drive - precision engineering. The degree of precision is reflected by the fact that the assembly of the head of a hard drive is so finely tuned that any contact or transaction they need specialized tools. The other aspect of electronics is as delicate and complex. Hard drives are finely tuned to complement the storage media and data signals they emit.
Enter two reason - it is in fact rocket science. Data recovery, whether recovery disk physical damage or logical, is a complicated process that requires knowledge, tools and environment to make it successful. Many times, people will run the disk repair utility to repair the problem. Bad idea indeed! The software is extremely complex. They are employed in complex steps and write to disk can cause a crash of the original data. Select a wrong option and you can say goodbye to your data! Disk repair utilities basically create a new album after washing away old information that was either completely removed or buried deep under the new data.
The ordinary man does not know that data recovery is not as easy as reformatting the defective media or the media. When you select the option to reformat the disk, it also allows the master boot record to be overwritten. A system reboot after you select to do a reformat and reinstallation of the operating system is another humungous error.
Data recovery work is done in clean rooms (class 100, for example, clean rooms) by trained laboratory technicians using special tools and advanced technologies. Only this combination allows the disk to be scanned thoroughly and firmly.
Here's how to set a typical data recovery is like - a room enclosed with external ventilation so that even the air in the clean room is not contaminated by air from other parts of the building. There is also a forum for particles that acts as an additional barrier to stop dust from entering the room. Guys Data Recovery held in high gear protective gloves, coveralls (with no fluff), masks, etc.. Before entering the clean room, they are blasted with a jet of air to remove dust and contaminants, and even then only, they begin the complex work of data recovery. Clean rooms are laboratories that have temperature and humidity controlled.
