Data recovery from external drives with SSD format can be performed with the help of simple and sophisticated hardware tools. These tools have the accuracy levels to restore the original functionality of disk drive and recover data from it. They can be purchased from online stores by searching for the appropriate type and purpose. It is easy for you to work with simple versions of the apparatus while complex devices need to be operated by professional hardware experts. Tools for read-write head replacement, head unstuck, spindle motor unstuck, spindle replacement, motor repair, platter exchange, PCB repair, disk imaging and SAS imaging are some of them. Of course there are many other tools too, which can be used for extraction of data from bad sectors, alignment of actuator components and firmware repair are some of them. The reasons for depending on professional data recovery experts for restoring drives and salving data are many.
Reliable hardware restoration: – When the hardware components of the external drive fail, they need to be scanned accurately to determine the exact nature and extent of failure. This process requires a combination of high end analog and digital tools which are available with professionals. We have developed a system consisting of latest hardware testing and fixing tools from Seagate, Maxtor, DeepSpar, Samsung and other enterprise level companies. Supportive infrastructure consists of donor devices for drives, boards and micro level components at the board and chip level hardware. We make it a point to utilize OEM software applications that offer complete compatibility for all the external drives with SATA, PATA, IDE, SAS, SD and other formats. They ensure complete restoration of hardware components in a reliable manner.
Accurate drive scan: – First stage of hardware failure repair starts with scanning of complete disk drive for mechanical, electrical and electronic breakdown. During this process, the technician will analyze the symptoms of failure by subjecting the device to Non destructive testing procedures. He may use USB based devices for this purpose which can test the external drive for drive spinning rate, head parking angle, disk controller motion, noise during read-write operations, platter alignment and damages etc. Further tests can be conducted by dismounting the hard drive from the casing and placing it within “housing compartments” of scanning devices. Scanning with hardware equipment also takes care of detecting most of the logical failures in the external drives.
Logical error correction: – When the drive is affected by virus & malware, file system corruption, partition and file deletion, OS collapse and other errors, the technician will immediately switch over to utilization of OEM software tools like MacAfee antivirus, Norton disk doctor, AVG and other enterprise applications for correcting these logical bugs. In most of the cases the external drive will be ready for usage after reinstallation of OS without affecting the file system and MBR. Unintentionally deleted files and folders can be recovered from these software applications.
Hardware component restoration: – The following section of hardware restoration considers each type of probable component breakdown and explains the overall procedure adopted by the hardware expert.
Actuator Read-write head replacement: – Head replacement tools work on the principle of non-contact method for replacing the read-write head. For this purpose the technician uses the tool to elevate the head from the platter to a height of 40 microns or above. Then he transfers the head from the donor drive onto the failed drive. Every head replacement tool is designed for a particular brand of external drive. Compatibility is the key factor in case of head replacement since the mechanism of every external drive is unique, for example Seagate, Maxtor, Samsung and Western Digital brands have their own head replacement tools.
Spindle motor repair: – One of the most prominent symptoms of spindle motor problem is the non responsive nature of External drive during read/write operations. Sometimes your OS may display error messages for non existence of medium, read-write error, accessibility error and so on. An illustration for this can be given when you try to save an office document into the external drive or try to copy it. If you check the specific folder you won’t be able to find that file, in spite of the OS showing “copy complete” message. In some cases you may not be able to open a document from the drive by double clicking on the file. The system displays an error message for the non existence of file.
In such cases the hardware technician will attach the spindle motor tool to the motor. The tool itself is based on a circular disk platform that can be rotated in 360-degrees. It is rotated until the stuck motor is freed on its axis. Now he can attach the drive to the desktop computer and recover data from the drive.
Spindle replacement: – In this process, the damaged spindle is replaced without disturbing read-write head, platters and spacers (These are the metallic or plastic separators placed between to platters of external drive for preventing two platters coming into contact with each other during rotation). The tool gently shifts the actuator and magnetic component holding it from the path of spindle. Then the technician will hold the platters in their place with the help of platter locking facility. Now the spindle is taken out from its position and replaced with a new one. Now the head is placed back into its original position and the drive is ready for data recovery.
Data recovery methods: – Once the disk is brought back into working condition, the other logical issues can be fixed with the help of OEM software applications that come with many of the hardware scanning tools. Many of them may not be so user friendly unlike their open source components, but the hardware expert will know the exact methods of utilizing them for data recovery. Some of the software tools from Seagate and Maxtor integrate the use of hardware tools for easing out data recovery process using disk imaging methods and data extraction from donor drives.
