Water-Damaged HDD Data Recovery: A Case Study
Hard disk drives (HDDs) and solid-state drives (SSDs) are essential for securely storing sensitive business information and personal data. These devices allow users to keep vital files such as photos, videos, and documents without hassle. However, both HDDs and SSDs are not impervious to failure and can succumb to various issues.
Due to their moving parts, hard disk drives are more vulnerable to physical damage compared to SSDs. Common problems include wear and tear of the spindle motor from prolonged use and potential head crashes that can damage the magnetic heads and platter surfaces.
In the event of an HDD failure, replacing damaged components is often necessary to recover data. This process involves using specialized hardware to read the contents of the magnetic platters and decrypting the data into accessible files.
Recovery of a Water-Damaged HDD
Recently, a water-damaged external hard drive was brought to our lab for recovery. The client had attempted to power on the device themselves, which resulted in bent magnetic heads and damage to the parking area.
After contacting our dedicated customer service team, the client entrusted their device to our skilled engineers. Upon arrival, our data recovery team conducted a thorough diagnostic evaluation of the hard drive.
At Prime Data Recovery Services, we operate in an ISO-certified Class 10 Cleanroom, ensuring that media storage with sensitive components is diagnosed in a controlled environment. This facility minimizes the presence of dust, microorganisms, aerosol particles, and chemical vapors while maintaining optimal humidity, pressure, and temperature levels.
Our data recovery specialists discovered moisture in the controller area of the client’s HDD, which had caused the microcontroller and other service circuit boards to fail.
Addressing Hard Disk Drive Controller Issues
Controller problems in hard drives are relatively common and can stem from power failures, overheating, moisture exposure, or occur without an obvious cause. In this case, moisture ingress had caused significant damage.
To recover the data, our engineer first replaced the magnetic heads and the parking rack. With a large inventory of hard drive components on hand, we avoided delays associated with sourcing replacement parts. The replacement of the block of magnetic heads (BMH) was successful, and fortunately, the BMH did not come into contact with the platter surface. If it had, the potential for complete data recovery would have been severely compromised, as data on scratched platters can be irretrievable.
Following the successful head replacement, our next step was to address the controller issues. Misdiagnosis can occur, especially when a drive does not spin properly; it can be mistaken for a sticky head or jammed motor. However, with our engineer’s extensive technical skills and experience, we were able to recover all the data and transfer the files to a new hard drive.
The client was able to verify the successful recovery through a remote file verification session, and we promptly returned their data.

What to Do if Your Hard Drive is Damaged
If you suspect your hard drive is failing, check its SMART (Self-Monitoring, Analysis, and Reporting Technology) status. SMART can diagnose hard drives and often predicts when a drive may fail. However, it’s essential to remember that SMART diagnostics are not always foolproof.
In some cases, a hard drive may be reported as healthy even when it is not functioning properly, or it may fail without any prior warning from SMART. If you identify any issues with your drive, it’s crucial to back up your data immediately to prevent loss.
If the SMART diagnosis does not indicate any problems but the hard drive fails, the first step is to stop using the drive. Continuing to operate the device can overwrite lost files, making recovery extremely difficult.
Avoid using free online recovery tools, as they can further damage your data or file system, potentially leading to irreversible data loss. The safest course of action is to contact a reputable data recovery company with the necessary certifications and laboratory capabilities.
