Mechanical failure is a result of hardware components & parts malfunction or breakdown. They can happen to fixed disk drives, flash cards, pen drives, CD/DVD drives and other types of internal and external memory cards. You need dependable systems based on advanced technology and tools for fixing the issues and recovery of data. Online software tools could be helpful in data recovery for the basic levels of component failure. You need to download and run them for fixing issues and restoring data. Most of the Open source software can help in extracting various types of files (documents, images, videos, SMS, email etc.) from PC, laptop, smart phones and tablets.
When it comes to deep rooted mechanical problems like spindle breakdown, platter and cylinder damages you need the help of professional technicians. This is because successful data recovery in these cases can be accomplished only after the mechanical parts and components have been serviced or replaced. We have established an infrastructure of qualified technicians with relevant experience for solving your disk drive problems and reliable data extraction.
Data recovery from Dead Drives
A drive is said to be physically “dead” when primary functionality like actuator movement, cylinder rotation, read/ write operations and booting are affected. In such cases it may not be possible to solve these problems with the help of software application alone. When you take your data storage unit to a technician, he will initially perform a diagnosis to determine the nature of failure. Once the diagnosis for mechanical failure is confirmed, the next step will be to identify the failed parts/ components.
USB drive Scanning and refurbishing
It is a card based hardware device which can be installed into Desktop PC. It is designed specifically for data recovery from USB drives. The system bypasses OS and BIOS in the drive to gain complete control over the process of drive imaging. This is considered to be an important feature as the drive is literally inaccessible by all the other known means.
Sector mapping: – Mapping of data sectors in the failed drive is one of the prominent features of any USB drive scanner. The system starts scanning sectors located in multiple layers and stores the visual image. Then it is split into sectioning based on functional and bad sectors. The process starts from the MBR (Master Boot record) and extends into the complete file systems. This is considered as a critical process as it can determine the “recoverable levels” of data from the drive.
Device resetting: – An effective USB drive scanner must be able to map the resetting status of the drive efficiently. As you know, the status of a functional drive and failed drive differs in many aspects of head assembly, alignment of I/O ports, PCB card design, voltage and power input. The USB scanner has a built in database which is used to compare the current drive status with the standard values. When variations are detected in these parameters, it becomes easy for the technician to determine the probable causes of drive failure.
Password unlock: – You might have used the password utility for locking your drive which needs to be broken in order to gain access. The scanner uses a Smart-Ware utility for removing the password stored at the device root level.
Error Interpretation: – USB drive errors could be accidental data deletion, factory setting, missing blocks of data in the Flash card, corrupt flash ROM, rooting issues etc. Android and smart phone devices normally suffer from these types of errors. The scanner attempts to diagnose multiple types of errors during its operation in order to zero-in on the most probable types. Once the errors are detected and interpreted they get stored within the scanner. This helps in fixing the errors accurately while the auto recovery tools start working.
Platform support: – The scanner/repairer tool needs to be capable of supporting multiple hardware, firmware and OS platforms. This will be required when the technician tries to transfer data from a failed android device onto another backup device which may not be compatible with the source platform.
Information security: – The tool should be able to preserve personal information stored in the storage drive without compromising on its security. For example you may have stored details related to your banking and ATM transactions, account and password information in your smart phone storage device. They need to be transferred in “as it is” format without leaking out any hidden data in the process.
Drive refurbishing: – Drive refurbishing could be done with the help of connected hardware tool. The technician finds a donor board and drive for restoring the data from the failed device. Before that he needs to fix errors in the PCB, read write head and other functional components. When the problem is with the firmware he uses the UDMA compatible tool for fixing the firmware issues. This requires a dedicated firmware library for the precise drive type which can restore corrupt firmware functions.
The next stage involves fixing or replacing of electronic components in the drive PCB which have been pointed out by the scanning device. Once these basic procedures are complete, the technician is able to access the root sectors of failed drive. At this stage he will be able to use the data recovery tool for imaging the drive onto an empty secondary storage device. This process will be able to create a mirror image of the source disk without leaving out even a bit of data.
Logical corrections: – Now the technician can leave out the corrupt drive and focus on correcting the logical errors in the data stored in secondary device. Boot sector and file systems are corrected. Meta data links are restored and deleted files are recovered. Now you can use the secondary drive by getting it connected into your portable device like the mobile, smart phone and tablet. This sort of procedure adopted by a qualified technician is said to be provide complete restoration measures for all types of USB devices.
