Hard disk drives (HDDs) feature a designated area called the parking zone, designed for the safe landing and taking off of magnetic heads. Each HDD is built to handle a specific number of head parkings, monitored by two sensors through S.M.A.R.T. technology. When power is turned off, the HDD employs an automatic parking mechanism that uses the kinetic energy from the spinning magnetic disks. This process utilizes the spindle motor as a generator, which helps move the magnetic heads to the parking position.
Despite their robust design, HDDs are still vulnerable to data loss. Issues can arise from the magnetic heads crashing onto the platters or being damaged during abrupt movements.
PITS Global Data Recovery Services specializes in advanced data recovery solutions for hard drives that experience any failure scenario. Our experts can temporarily restore functionality to the drive and safely extract all data.
Seagate External Hard Drive Data Recovery
Recently, we received a data recovery request for a Seagate External Hard Disk One Touch USB 3.2 Gen 1. The client had accidentally dropped the drive while transferring files, leading to clicking sounds and rendering the drive undetectable by the operating system. After searching for a reliable data recovery company, the client entrusted his important files to our team.
Upon receiving the drive, our data recovery specialists began the diagnostic process immediately. The first step involved unsealing the drive and inspecting its internal components, conducted exclusively in our ISO Certified Class 10 Cleanroom. This controlled environment minimizes particle ingress and protects sensitive components from dust contamination.
Evaluation Findings
Our evaluation revealed that the magnetic heads had been pulled away from the platters when the power was off, damaging the parking zone without allowing the heads to make contact with the disk surfaces. After completing the technical inspection, we informed the client of the recovery success chances and estimated turnaround time. Once we received his approval, we proceeded with the recovery process.
Seagate One Touch HDD Parking Zone Recovery
Our engineer initiated data recovery by selecting an appropriate donor drive. This stage is one of the most complex in the recovery process, but our extensive inventory of spare drives facilitated a successful match.
Replacing the magnetic head assembly requires meticulous attention. Our technicians, equipped with deep knowledge and experience, used specialized MHA pullers to remove the heads without causing contact with other devices or surfaces. Given that any mishandling could lead to irreversible damage, our specialists exercised utmost care during this critical phase.
Seagate External HDD Bad Sectors Recovery
During recovery, the client’s drive exhibited errors due to incorrect checksum estimations when reading information from certain sectors. These sectors were flagged as unstable by the firmware and subsequently marked as bad.
To prevent further disk failures, our engineer employed various methods to modify the defect processing algorithms. This involved disabling and reassigning the RAM disk and modifying trace information modules. The distinct structures of the translator and defect tables, along with variations in hard disk software, necessitated a tailored approach for each situation.
After successfully recovering the files, they were copied onto a new hard disk drive. The client reviewed the recovered data and approved our work. We promptly returned his data, successfully closing the case.
Conclusion
At PITS Global Data Recovery Services, we are committed to providing effective solutions for hard drive failures, including those affecting Seagate external drives. Our skilled technicians use advanced techniques to recover valuable data, ensuring that our clients can access their files when they need them most. If you experience data loss, don’t hesitate to contact us for professional assistance.
