EasyStore hard drives are prone to various common data loss problems. One of the most frequent failures is the collapse of the block of magnetic heads (BMH), which can lead to significant data loss.
A notable challenge with EasyStore drives is the poor compatibility of donor spare parts, resulting in a lower success rate for replacements. Thus, recovering data from these drives after a BMH failure requires an experienced data recovery expert who can carefully select a matching donor. This process is critical to the success of the recovery.
To maximize the chances of a successful recovery, a specialist must have both substantial experience and access to an extensive database of spare parts. Additionally, advanced data recovery tools in a well-equipped laboratory are crucial for carrying out these complex tasks.
Magnetic Head Failures in EasyStore HDDs
When the magnetic heads fail, it is often accompanied by a clicking sound, signaling that the drive is not functioning correctly. In such cases, the hard drive is typically not detected by the system, making direct data recovery the only viable solution. This process must be performed in a certified cleanroom, as even the smallest dust particles entering the sealed HDD case can lead to permanent data loss.
Specialized tools are used by experts to safely examine the surface of the magnetic platters and assess the condition of the head block. If any damage is found, the BMH is replaced with a compatible donor unit. Afterward, data is read sector-by-sector, and transferred to a new working medium.
Case Study: EasyStore HDD Magnetic Head Crash
Recently, a customer brought an EasyStore external hard drive to us for data recovery. The failure occurred after the customer accidentally disconnected the drive while editing photos from a recent shoot. During the disconnection, the magnetic heads were writing data onto the platters. The sudden power loss caused the heads to crash into the surface, leading to circular scratches on the platters and damaging the magnetic coating.
In this case, our experts replaced the faulty block of magnetic heads with a matching donor part. Afterward, the platters were cleaned using an ultrasonic cleaner, and data from the undamaged portions of the drive was successfully recovered.
However, it’s important to note that irreversible data loss can occur when parts of the platters are physically damaged. This was the case here, as the data on the scratched sections was lost permanently.
Why You Shouldn’t Attempt DIY Magnetic Head Replacements
It’s crucial not to attempt replacing the magnetic heads yourself, even if you have a similar working drive and the necessary tools. Improper handling or replacement of the magnetic head unit can reduce the chances of successful data recovery and potentially cause further damage.
Professional Data Recovery at PITS Global Data Recovery Services
At PITS Global Data Recovery Services, we have the specialized tools and expertise required to recover data from hard drives with failed magnetic heads. In our lab, experienced specialists use an ultrasonic cleaner to wash and prepare the heads for safe replacement, minimizing the risk of dust contamination.
In the case of this EasyStore drive, we successfully replaced the magnetic heads and recovered the requested data. The scratched areas of the platters, however, resulted in some irretrievable data loss.
