Hard drives can experience many different kinds of problems. The majority of issues fall into three basic categories: logical failures, mechanical failures and firmware failures. If you want to recover your data after a fault, you must understand what kind of failure you’ve experienced so that you can apply the correct solution.
42% Is Caused ByLogical Failure
Understanding Hard Drive Logical Failures
Hard drives store files using a number of different schemes that help them optimize space usage, deal with data errors and solve other common problems. When your computer encounters a drive whose storage doesn’t fit the expected patterns, it usually won’t recognize it as a readable device because it doesn’t understand what it contains.
How Do I Know If My Hard Drive Is Experiencing a Logical Failure?
Different things can induce logical failures. For instance, a hard drive’s Master Boot Record, or MBR, may have been corrupted so that the computer can’t retrieve boot instructions. Similarly, viruses or malware can also cause operating system, or OS, errors by preventing the retrieval of necessary files. In some cases, incorrectly shutting down, deleting, reformatting or partitioning files may cause corruption.
Each of these problems has different symptoms. With MBR and OS file errors, your computer may not boot at all if the primary drive is faulty, or it may present errors. In other cases, it will start up, but it might be slow, or you’ll discover that data on a secondary drive mysteriously goes missing. In any case, you’re likely to require a recovery or retrieval service such as a deep scan to rebuild missing information.
40% Mechanical Failure
Understanding Hard Drive Mechanical Failures
Your Hard Drive Failure are complex devices that include numerous components. If any of these important parts become damaged due to shock or control errors, they may lose the ability to do their jobs. To correct mechanical problems, most users have to send their drives off to clean-room facilities so that retrieval experts can open them, temporarily replace their parts and transfer the data they contain to fresh, functional drives.
How Do I Know If My Hard Drive Is Experiencing a Mechanical Failure?
Common symptoms of mechanical disk failures include:
7% Firmware Failure
Understanding Hard Drive Firmware Failures
Firmware failures are similar to logical failures. Your computer will recognize the drive as a drive, but due to problems with its firmware, or the software that controls the device, it won’t be able to access the data. Only around 15 percent of data retrieval jobs necessitate firmware recovery, as it’s the least common failure mode
How Do I Know If My Hard Drive Is Experiencing a Firmware Failure?
Firmware tells a hard drive how to start up and function normally. It lets the control circuit know when to turn on the motor, move the read-write heads to access or write data and perform other critical tasks. As a result, the symptoms of a failure may vary widely and produce a range of behaviors that are difficult to diagnose.
Where Is the Firmware Located?
Hard drives store firmware in different places. Part I is stored on the printed circuit board, or PCB, behind the drive, while Part II is written on the drive’s platters in specialized service tracks. Since firmware is data instead of a physical component, it’s not something you can simply see and replace. Recovery specialists often have to reconstruct devices using parts from similar drives, which requires proper clean room facilities and experience.
11% Deleted Failure
You will know if the error your hard drive is experiencing is from a deleted data problem because most likely it’s something you did knowingly, or by mistake. Even errors such as deleted data can be reversed by capable data recovery experts, like the ones at TTR Data Recovery.
If your hard drive isn’t experiencing the symptoms of logical or mechanical failure, and your data seems to be missing, don’t act without giving our experts a call first.
