Address to deserve the Hard Disk. These store the data on one or more magnetic plates enclosed in a metal container in which air is highly filtered. The data are read and written on the plates from rotating magnetic heads operating on both sides of the dishes, flying only a few nanometers above the surface. Everything is controlled by un'elettronica control. It goes without saying that a hard drive is the most complex, and also the one with larger storage capacity, 1500Gb reached for support. 

The physical damage and loss of data on a hard disk may appear to be borne by its various components and then: 

1. Problems of command to electronics, including CPU, driver of the motor, the logic of reading the data, preamplification of the signals coming from the heads, the movement of the actuator arm for reading. 

2. Problems in this firmware nell'elettronica command and / or the disc itself 

3. Problems in the read heads and / or reading in the arm 

4. Problems in the engine rotation flat 

5. Problems in flat magnetic decay or alteration (scratches, lines) of the same 

To make the data recovery is necessary to put the hard drive in a position to work even momentarily. This can be achieved by the repair or replacement of some components (electronics, engine, heads), and re-correct the firmware disc that "matches" the electronic card to the disc. The opening of the container of the dishes must be done in a controlled environment (clean room) to prevent dust particles or other contaminants from damaging the magnetic surface. The handling of the plates must also ensure that the orientation angle between plates and between the engine and the same number of dishes including a few micrometers, or risk permanent loss of data, which are stored sequentially on the various dishes. Were also developed some techniques, such as Blindtrackcopy, and through the use of atomic force microscope to allow the reading of the plates without using the original electronics and mechanics. 

It follows that the recovery of data can be made only by competent persons or companies that possess a specialized electronic equipment, mechanical high-precision, hardware and software for reprogramming the firmware and the piloting of the discs in "factory mode" an environment that allows the processing inside the discs without contamination by external agents. 

Memory cards in various formats, storage media in embedded USB, USB keys....

These media have their main feature was the absence of moving parts. The data are recorded in digital non-volatile memory (flash memory). Problems are so widespread nell'elettronica storage or control. In these cases, if the memory chip is still intact the data can be extracted from it and reconstructed using special software algorithms. 

Optical storage media (CD, DVD, magneto-optical discs) 

These media are read by a laser beam that receives the data [binary] (1 / 0) depending on the refraction or refraction of the beam. It follows that the cleaning of the reading of the medium itself is crucial. The total breakdown of the support often involves the impossibility of recovery, to the difficulty of aligning the data traces. Breakage may allow partial recovery. Deep scratches may be removed by mechanical polishing, but depends on the layer of plastic on the bottom of the disc, the higher the original discs, not in the burned. 

Magnetic media (hard disk, floppy disk, ZIP, DAT, etc.) 

These devices store data on a magnetic substrate, in linear or rotary motion. It follows that it is important to the media by magnetic fields and maintain the cleanliness of the media and readers. This is particularly true in the floppy, ZIP, DAT and cassette in general. In these media the magnetic medium is not in a sealed container and in the long run the dust particles can penetrate altering and impairing the magnetic characteristics. These media are also very sensitive to storage conditions, and high temperature, direct exposure to sunlight, magnetic fields (screens, mobile phones and the like) may modify the support and prevent the correct reading of data. In these cases, in addition to the cleaning media and player, the user can do little else. Specialized firms can do readings with different systems, using appropriate reading devices designed to make reading deeper or higher, by calculating the average, up to the reading by atomic force microscope (see Blindtrackcopy) 

In case of physical damage is rare that a software solution. The physical damage usually occurs with blocks of reading, not full access to the support, abnormal noises, burning of components. Usually, the action for recovery are not in reach of the. Recovery is possible in specialized firms with specific equipment and laboratories equipped with protected environments (clean room). 

Depending on the type of support the case and therefore the type of intervention is different.

In many cases the damage that leads to the loss of data is of type logical. It's that is linked to the storage system, or errors of others, and does not involve a physical defect of the media. It continues to operate normally, it can be reused, but the data are no longer reachable. 

Different causes, often related to the type of support. In those typically removable data loss can be caused by removal or disconnection of the media before they were actually written the data. This is particularly common in digital devices connected via USB. In these cases the data is not recoverable because they have never received in support. Same goes for burning CD or DVD interrupted. It's possible to restore data in case of cancellation by mistake. It's fundamental act correctly and quickly, because the operating system reuses the space very quickly made available again. Even in case of malfunction of the operating system recovery is likely. Modify the support, install recovery software on the disk where the data is lost is not recommended for a high risk of overwriting the leases containing the lost data. The recovery operations are conducted by trained staff to do so or by specialized firms. It's possible to use specific software to recover data, as long as you follow the instructions and warnings above. 

It is now established practice of making regular copies of back-up of their data in order to minimize the consequences of a possible crash or data loss of the system. Sometimes, however, Murphy's law strikes, and following an accident on the original system is discovered that the copies back-up is you can not read! 

Sometimes however there and the need of having to again access to historical archives now available only on media back-up and discovered at that point that the weather or other causes damaged them, making them unreadable. 

In our laboratories we are able to reconstruct the media physically damaged, make a continuous reading of data and a reconstruction of the archives. 

We also service transposition of data from old tape back-up running, you do not have more than one unit of the original reading, on new media. 

This is a partial list of media types most commonly treated by us:

Diagnosis free and without obligation 

If the data on your media are inaccessible or illegible, we carry out on your support in our first laboratory diagnostic service and free estimate without obligation. At this stage, send a list of files that can be recovered with a description as to their status (intact or if they are corrupt or unreadable). This will help to follow up the work itself already knowing the possible results. If instead it is impossible to recover data that is lost, nothing will be due for this first phase of analysis and diagnosis, because even in this case we think it is fair that our clients pay only if they obtained results. 

A RAID system is a particular configuration in which several hard-disks are concatenated with each other, allowing a user to "see" as one or more logical volumes. You can configure the RAID system in several ways, including creating forms of redundancy of data. 

RAID stands for Redundant Array of Inexpensive Disk, an architecture used to implement systems of hard disks of high capacity with superior safety: significant feature of a RAID system is that a single fault to a hard disk does not l 'shutdown, which can then continue to operate. 

RAID systems are usually equipped with a set of management tools that allow you to reconfigure the system or restore the functionality in case of malfunction. In the case in the previous configuration is no longer accessible, there are important data for you, you must be especially careful when using these management tools, as an improper use may cause an irreparable loss of previous data and must be performed by experienced staff.

A RAID system is often presented in a configuration that requires its reconstruction on a machine in our lab just to make the first phase of diagnosis and so the diagnosis for some types of RAID disks can have a cost, as opposed to us for all the individual disks and other media (free diagnosis). Also depending on the configuration may be necessary to send not only the discs but the broken chain of discs, rather that the controller of the disks or even the whole station. 

The pen-drives or USB keys are removable storage media, accessible via a USB port of your computer. Contain a component of solid-state memory managed by a small electronic schedina: we can reconstruct the component fails to access the original data or resolve all bugs related to the operation of the logic. 

The CD-Roms and DVDs are optical media that have no internal mechanical parts, electronic components. At first glance could seem that if the support is not more readable there is no longer anything to be done. Indeed, if these media are physically damaged there is just nothing more to give. However, there are numerous cases in which our tools are able to recover all or most of the data originally present and which were no longer accessible. In the case of floppy disks, the primary cause of the impossibility of access and reading, and was due to a mechanical problem of the casing. We can reconstruct the original media support a new functional, so you can regain access to data.

The development of new digital technologies has led to the widespread diffusion of new generations of digital cameras that store images in different types of removable drives, each with distinct characteristics and performance, 

These are some of the most widely used digital formats, which Ondata International currently operates to recover the data: 

- Memory Card 

- Compact Flash 

- Micro Drive 

- Memory Stick, MS, MS Duo 

- Smart Media 

- Secure Digital, SD, Mini SD 

- Flash Memory 

With these digital cameras is no longer the danger of exposing the film irretrievably lost the photos taken, but the new digital photos can be deleted accidentally. If this happens, it is said that digital photos are made lost: Wave International can recover, with the same quality of image with which they were made. In order to do this it is necessary that have not been overwritten new photos over the past, or have been made attempts to recover data from memory card with invasive methods that have caused the total loss of such data. 

Diagnosis free and without obligation 

We perform on your support in our first laboratory diagnostic service and free estimate without obligation. At this stage, send a list of files that can be recovered with a description as to their status (intact or if they are corrupt or unreadable).

If instead it is impossible to recover data that is lost, nothing will be due for this first phase of analysis and diagnosis, because even in this case we think it is fair that our clients pay only if they obtained results. 

If your data were lost because they have been deleted and removed from the basket or the disk has been formatted, you can still retrieve them by using appropriate instruments. When given to a computer the command "delete", in fact, the operation is carried out is to not make such data more accessible to the system by making that space available for additional records (this is because for a computer to physically delete the data is a demanding and tedious). However, if these spaces made available by the cancellation are written to new information, the information above are sunk at this point, because they are physically overwritten by new ones. 

If the media is fully functional, are available on the market several commercial software tools that allow in many cases to solve the problems of recovering data lost due to cancellations and formatting. 

This solution is the easiest, because it allows you to recover your data directly to home, at reasonable costs: if these efforts do not give the expected results, we recommend you send your support to make a recovery in our laboratories, which instruments are equipped with much more powerful and complex than those intended for commercial use. 

Even in these cases is subject to our terms of service:

Our operators will assist you to manage your situation as best as possible. 

Request a Form Processing 

To retrieve your data, or even for a first analysis in advance, we need to get your disc in the laboratory, and that any disk that is clearly identified arrivals. For this we must ask our Form Processing that in addition to sum up all our modes of operation and instructions on how to proceed, contains one part to be filled with your data and returns a unique number processing: the code with which you registered your and what do they mark your support in its operating procedures. This form should be required for each production. 

In the case of data erased or lost due to incorrect formatting, virus attacks or similar problems, it is important to point out in Form Processing files and folders that must be recovered.

The hard disk, or hard disks are special electro-mechanical equipment for proper operation that need to have its interior completely isolated from: why are sealed with a special process that creates a vacuum inside them. To retrieve the data is often necessary to open the disc to access the mechanical components or plates of the disc itself. An analysis of the disk in the lab allows the detection of the fault immediately, and the definition of the solution to be pursued for the recovery of data. In the case of mechanical problems which should open the disk, this operation must be conducted in a clean room, a sterile and protected environment in which it is necessary to avoid irreparable damage to the status of the disks themselves. 

Diagnosis free and without obligation 

For all the different types of hard-disk, we perform in our laboratories a first diagnostic service and free estimate without obligation. We do this because the costs of a data recovery service depend to a large extent of damage suffered, and consequently the type of processing that is required. It is therefore difficult to define a cost for data recovery service in the laboratory without viewing the medium in question. Because we feel that right before you commit to each other both parties know what we will. 

Exclusive "no data - no pay" 

For all our services, in case of non-recovery of data will not be charged any cost. Why do people do this to retrieve customer data, but there seems also right that customers should not pay anything if our service has not produced the desired results. 

Our laboratories are equipped with all the technologies needed for the proper handling of the media in terms of ensuring maximum reliability and security with: our equipment and facilities are the most advanced worldwide. We operate using the most stringent security measures, the laboratories are located in buildings protected by security systems operating 24 hours at 24 with a central alarm system with closed circuit cameras and inputs are controlled by an electronic system that allows' access to authorized personnel only.
