- Hard Disk Recovery
- 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.
- Recover Digital Storage Media
- 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)
- Physical Damage - restore data
- 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.
- Logical Damage
- 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.
- Data Recovery Systems
- The recovery data (or data recovery), in computer science, is to recover data from storage media when they are damaged, corrupted or inaccessible. In the field of criminal investigation, the recovery is to recover material previously transited and / or deleted, on computers of people under investigation. The storage media that may be subject to recovery are virtually all storage media, although the most common are in order: hard disk, USB removable media (USB key), memory cards, floppy, CD, DVD, tape, magneto-optical media. The damage of the media can be either physical or logical type (in software), and can cause sudden stops or unavailability of the system and / or data.
- Tips on restoring data
- More than 30% of cases it is estimated that recovery of data is impossible because of human and not to damage hardware. Kroll Ontrack leader in providing solutions for backup and data recovery services has drawn up a list of those that are the most common errors that users make when there is a problem of loss of data on the hard disk of their computers, as well as give some tips on what to do and what not to do when faced with a similar case. - Conduct in hazardous situations damaged hard disk are certainly to be avoided. The do-it-yourself, without an adequate knowledge of the hardware and the necessary technical skills, can lead to total compromise of the device, making impossible any future attempt to retrieve data - Clean the disc. In most cases, the user proceeds to format the disc after restoring data from backups made previously. Once you clean the disc proceeds like a script for a new installation of software such as operating system and various applications. Although the transaction does not appear to be the most complex, but often one realizes too late that their backup is not updated or worse does not work. In this case there are solutions that allow you to recover data. The Board, however, is always to check the operation of the backup and its status update before proceeding to the formatting. - Substitution of components: It often happens that in case of malfunction of the hard disk you try, improvising technical, to replace the failed drive by purchasing a similar, without considering that the components of a hd containing information of its membership drive the technical specifications of its new component, and especially that opening up the disc in unfit environments can cause irreversible loss of data. - Block of the disc, or if you find that the drive and the heads are firm, for example because there is no noise due to the normal rotation of the flat disk, the most common mistake is to remove the disc and or try to shake him of taps, hoping to break the deadlock. Nothing more wrong! because it threatens to severely damage the disk at the physical level. In these cases is often that the head that graze the surface magnetic rovinino the surface of the plate that contains the data making it impossible to scratch and all future reading. - Infiltrations liquids such as the overthrow of a glass. The same remedies are used, such as groped to dry the disc with a hair dryer, with the danger of only worsen the situation. The appropriate behavior in these cases is to keep the drive moist, thus preventing the impurities will be established on the plates inside the drive and contact the assistance of a professional provider of data recovery. - Using improperly system utilities for recovering data. It is a strong temptation for the user who faces the risk of losing valuable corporate data, to use them. Classic examples are CHKDSK, Mac Disk Utility or fsck. The problem is that if the drive is physically damaged the use of these programs has resulted in further damage to the hard disk, making it harder to recover data. Conclusions: In most cases, do not improvise technical do-it-yourself but contact an expert who knows how to resolve the situation and prevent loss of information. In over 80% of cases, you can retrieve the full content of the medium, even in cases apparently insoluble, but you do know!
- Retrieving data from tapes, drive back-up
- 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: Type Model Capacity DLT Tapes 2000-4000 GB 10/20 - 15/30 GB - 20/40 GB Tapes DLT 7000 35/70 GB Tapes DLT 8000 40/80 Gb - VS80 - DLT1 LT01 tapes DLT 100/200 GB DLT tape 110/220 GB SDLT1 4 mm DAT DDS1 - 2 - 3 2 / 4 Gb - 4 / 8 GB - 12/24 GB 4mm DAT DDS4 20/40 GB DAT 8mm Exabyte 5 GB - 5 / 10 Gb - 7 / 14 Gb Elianto 820 DAT 8mm Mammoth 1 / 2 20/40 Gb - Gb 60/150 DAT 8mm AIT-1 35/70 GB DAT 8mm AIT-2 50/100 GB TR4 TR5 Travan 4 / 8 GB IDE / SCSI - 10/20 Gb NS20 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.
- Recovering data from RAID systems, AS 400 and other systems
- 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.
- Retrieving data from pen-drives, CD-Rom, DVD, floppy disk
- 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. 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). 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. How to manage the recovery of your data medium: Please call our Customer Service for any questions or request. We tried to make our website user-friendly and comprehensive consultation, but often we know that many questions or concerns to handle better with a direct conversation. Our operators will assist you to manage your situation as best as possible.
- Retrieving data from cards cameras
- 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). 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.
