The logical malfunction is damage to an arbitrary number of sectors on the hard drive to the point where their reading by the heads in the normal mode of the hard disk becomes impossible. Another scenario is when the surface of the device degrades to a state where reading sectors is possible, but it is extremely slow. It does not fully allow the drive to work with the operating system and user data.
Seagate Hard Drive Data Loss Reasons:
- Physical Wear and Tear of The Drive Caused by Long 24/7 Operation
- Various Mechanical Damages on The Drive
- Drive Overheating due to Operation without Cooling
- Low-quality Power supply, Unstable Mains Voltage, No UPS
- Incorrect Extraction of The Hard Drive from a Running Computer
PITS Global Data Recovery Services provides data recovery solutions for various hard drive failures. Our experts work only using cutting-edge data recovery tools in an ISO Certified Class 10 Cleanroom.
Seagate Barracuda HDD Data Recovery
The data recovery team received an internal Seagate Barracuda 3000GB Hard Drive. According to the client, all the data suddenly disappeared. The disk was not dropped. The customer safely packed the device and sent it for an evaluation.
Our engineer received the drive and immediately started the technical inspection. The primary evaluation showed the absence of extraneous sounds when power was applied. The SMART scan indicated a large number of reading errors. The external drive was used in a laptop running on Windows.
Considering that Seagate Barracuda drives do not write diagnostic messages to the terminal, the drive was connected via the SATA interface to our system. In the status registers, there was a signal of readiness at any appeal, including reading the passport. There were no extraneous sounds found.
In order to access the service area of the drive, the disk was switched to the technological mode, which allows it to work with a specialized utility. In this mode, access to service information was blocked, and the disk was rebooted.
A drive that has become ready in an emergency due to the impossibility of reading the service area at false addresses allows loading the microcode overlays. They are necessary for working with service information modules in RAM. After reading and analyzing the service area, the diagnosis was clarified: defects in the service area.
Seagate Barracuda HDD Service Area Recovery
The engineer started recovering the data by assembling the modules necessary to begin analyzing unique critical modules, that is, to ensure the ability to export user data to a healthy drive. The next step was the selection of a compatible donor drive model to perform the hot-swap procedure.
In case of any damage to the service area of a hard drive, our technicians perform sector-by-sector cloning of user data to a working drive. Only such an approach can guarantee complete and safe data recovery.
There are no standard and template solutions in data recovery in case of service information damage. Every recovery strategy is customized for the specific device.
When a compatible donor HDD was found, our engineer started recording in the service area of the donor modules from the failed drive required for translation. After the initialization of start information in the RAM of the drive with subsequent start on the HDA of the faulty disk, he started to extract crucial data.
Seagate Barracuda HDD File Structure Recovery
Two main methods exist for copying data from disks damaged by error sectors. In simple cases, when the MFT file table is not damaged and can be subtracted, a virtual map of sectors occupied by user data on the disk is built.
In the client’s case, only sectors containing information were copied, and empty sectors were not copied. It speeded up the copying process and reduced the likelihood of increased drive failures during sector-by-sector image creation.
In cases where the MFT file table is damaged, the location of files and folders on the disk is unknown. We have to make a full sector-by-sector copy of the entire disk. After its completion, our technicians restore the logical structure of the file system on the disk where the sector-by-sector copy was made.
All the data was recovered and shipped back to the customer upon receiving his confirmation. Our data recovery expert deleted the recovered files from our servers.
