Hard drives are the most common storage media in desktops, laptops, and servers. Technologies for the production of hard drives are constantly evolving, the density of disks is rising, and the speed is increasing. Hard drives are constantly improving in their level of durability and reliability, but the mechanics and electronics are still susceptible to failures.
Electronics malfunction is damage to the hard disk board. As a result of this collapse, the drive stops spinning the engine and is not detected in the system.
Usually, damage to the disk controller is either electrical or mechanical. In the case of a severe electrical breakdown, the switch of the magnetic head unit may fail, which will require replacement not only of the control board but also of the magnetic head unit itself.
To recover data from a drive with a damaged electronics board, specialists need to find a drive of a similar model, then remove a working controller and put it on the damaged HDD. After that, they copy sector-by-sector the entire disk to a new drive.
PITS Global Data Recovery Services’ engineers perform highly qualified HDD data recovery. They safely replace the circuit board and access all the crucial files.
Samsung Internal HDD Data Failure
Recently, our company received a Samsung drive data recovery request from a local photo agency. They were saving all the shootings on the Samsung 500GB hard disk.
During heavy loads, the media storage stopped showing up, and they lost access to their data. Their technicians tried to read the hard drive on a PC via SATA connectors, but the device was not showing up.
After researching for a data recovery company, the client decided to entrust his device to PITS Global Data Recovery Services. During the consultation, they decided to go with an expedited evaluation, as the problem needed to be solved as soon as possible.
Our data recovery team received the device and immediately started the evaluation. The device was not detected in the operating system, so the engineer had to unsolder it in our ISO Certified Class 10 Cleanroom.
The expert used control and measuring equipment such as voltmeters, ohmmeters, and combined instruments. If necessary, an oscilloscope and a frequency counter are used.
To diagnose a repairable hard drive electronics board, in most cases, a voltmeter and an ohmmeter were sufficient. The evaluation showed that the hard disk drive heated, and the PCB burnt out because of overloads.
We informed the customer about the evaluation results and data recovery estimate. After receiving his approval, our dedicated engineers begin to restore lost files.
Samsung Hard Drive PCB Recovery
As PCB failed, the device could no longer function, making the files inaccessible and corrupted. In this malfunction, our data recovery engineers replaced the damaged PCB with a new one from the same model HDD.
When choosing a printed circuit board, Samsung media storage, the number engraved on the printed circuit board must match.
First, the data recovery expert removed the circuit boards from both hard drives. Then he replaced the damaged printed circuit board with a new one.
After the replacement, the drive’s spindle motor spun, but the disk was not detected, so the technician needed to transfer the ROM chip from the damaged board to the new one. The ROM chip is integrated into the main controller chip if there is no compatible one on the PCB. In this case, we would need to solder the main chip.
Our engineer successfully transferred the ROM chip as well and started extracting the data, but the data could not be accessed. Replacing the PCB ended up with a corrupted file system.
Samsung HDD File System Recovery
The client’s hard drive was formatted using an NTFS file system. NTFS supports storing metadata. To improve performance, reliability, and disk space efficiency, NTFS uses specialized data structures to store information about files.
Our engineers restored the file system, using our decrypting keys for corrupted files and file systems.
As soon as the recovery process was completed, we scheduled a remote file verification for the client. He approved the results, and we shipped his recovered data and media storage back.
PITS Global Data Recovery Services offers highly confidential and fast solutions for data storage devices. Our highly experienced data retrieval experts can safely extract data from various types of malfunctions. They securely fix corrupted all lost files and recover data from media storage.
