Guide On How To Restore Data From HDs and Flash Drives All necessary data is generally stored on the hard disc drive. It is protected neither from third-party software influence nor from the operational system nor from a hardware failure nor from a virus attack. Be it physical damage or formatting of your disc containing your information – your valuable data is irretrievably lost. While the loss of photos, music and films is not so terrible, the loss of important reports and documents is highly critical. Nevertheless, even after full formatting there is a chance of restoring even a bit of information. You shouldn’t do it on your own; you’d better trust your medium to competent professionals.
Data Recovery From Files Even today in the era of Internet technologies, the data recovery problem remains highly acute. Necessary files might be deleted for many reasons. For example, it may be a result of physical impact on the HD or a virus attack. Is your HD no more visible in “My Computer”? The hard drive is displayed as not formatted? Here are some possible reasons. You have removed your flash drive incorrectly or you have switched off your computer improperly. Moreover, this error is possibly a result of the software failure. Have you deleted your data by mistake? Have you formatted your disc without backing up your information? Do you think all your files are irretrievably gone and data recovery is impossible? In most cases you have a chance of restoring your information. After being deleted files remain on the HDD for the time being, but the user can’t see them. This means that files have changed their location on the HDD unless they have been overwritten. Data can be restored by defining location of needed information on the hard disc. Overwriting makes recovery impossible because of high-density data recording. Data recovery is not as easy as it may seem at first sight. More and more frequently a user tends to restore lost data on his own. It often becomes a problem even for a professional. You shouldn’t try to restore data by yourself as a certain set of utilities and programs is used during the process of data recovery.
Stages of Data Recovery At the very beginning you should perform device diagnostics (troubleshooting) to identify failures. Failures are divided into three types: physical, logical and electromechanical failures. Physical failures are failures that occur as a result of external mechanical impact on the HDD. The hard drive thus breaks down partly or completely. There might be different symptoms. The HDD is not recognized by the BIOS or the OS. The device is recognized, but it makes strange knocking or clicking noise when reading. Logical problems. The disc is physically in a good order. Initial processes of switching-on, recognition by the BIOS, etc. occur normally. A logical failure can be caused by a virus, hardware or computer problems on the whole. If the official firmware is damaged, the disc is generally not recognized by the BIOS or recognized incorrectly. To access the information the HDD enables the firmware first and then grants access to data. In case of physical damage replacement of HDD parts with those of another device is performed if possible. After that a read operation follows. As a result neither “patient” nor a “donor” can be used anymore.
Logical failure identification is generally based on getting a byte-by-byte medium image and then extracting specific files from it. If you have received an image, you can get your data using any program capable of working with medium image files. Data is received using a hardware-software system. If electromechanical damage occurs, you can replace bad components (a board, a boot ROM, a restrictor, a motor, etc.) To restore data from an information medium that functions normally is a trivial task. Possibilities offered by a hardware-software complex are usually enough to restore data. Trust your data recovery to competent experts if the lost information is of great importance to you! But what should you do if the medium is out of order? There are ways of data recovery from it. Physical or electromechanical damage requires repairing. Only after that it is possible to state whether data can be recovered or not.
Data Recovery From Flash Drives Our organization is professionally engaged in data recovery from flash drives. We are glad to offer you services of data recovery from different types of flash memory: USB Flash, Mini, MMC, RS MMC, CF, xD Card, SD, Smart Media, Trans Flash, Memory Stick.
Types of Flash Drive Failure I. Logical failure is an extremely common type of a fault. The main peculiarity of flash drive logical failure is that the medium is recognized by the OS, but it cannot be opened. The necessity of recovery of files deleted by mistake from a flash drive occurs due to incorrect software work or the age of the medium. Data can be easily saved, but canâ€™t be read using standard tools. Then data recovery is performed using a special complex. II. Physical damage 1. Damaged USB connector. If this kind of damage occurs, data recovery doesnâ€™t take much time. In this case the data recovery procedure consists in soldering a connector to its original place. It will take only a few hours to restore your data. 2. Mechanical damage In this case a full data recovery from a flash drive is required. Medium demounting is performed as a result. 3. Electrical damage The main reason for data recovery from a flash drive is a problem with USB adapter power supply. This kind of damage interferes with the work of the disc controller, but flash memory remains functional. Thus, data recovery is possible. Flash memory is removed, and data recovery is performed by reading information form chips. By its nature data recovery from memory cards is just a little different from data recovery from HDDs. Data restoring in home conditions usually leads to full data loss. Therefore, address to professionals if you want to obtain guaranteed results.
