A logical failure in a hard drive refers to issues with the software or logical components of the drive, causing an inability to access data properly.

Common examples of logical failures include:

1. Accidental data deletion
2. Incorrect formatting
3. Lost partitions
4. File corruption
5. Improper operations
6. Virus infections

If your electronic storage device experiences a logical failure, it is advisable to immediately stop using it and seek professional data recovery services as soon as possible.

A physical failure refers to issues or damage in the hardware components of a device, resulting in the hardware's inability to function properly or read data.

Common examples of physical failures include:

1. Hard drive not spinning or unable to start up
2. Unusual noises coming from the device
3. Head crash or damage
4. Damaged circuit board
5. Surface damage to the disk platters
6. Malfunctioning fan

Compared to logical failures, physical failures typically require hardware repair or replacement. This necessitates specialized hardware repair techniques and equipment, thus seeking professional services is essential.

If your electronic storage device experiences a physical failure, it is advisable to immediately stop using it and seek professional hardware repair or data recovery services to ensure the safety of your data.

The success rate of data recovery depends on several factors. These include the severity of the failure, the complexity of the hardware and software involved, the type of electronic storage device, the type of operating system and file system, and the expertise and equipment used for data recovery. As a result, the success rate of data recovery can vary in different situations.

In some cases, the success rate of data recovery can reach 100%, such as in simple issues like accidental file deletion or damaged partition tables. However, for more complex situations, such as hard drive failures, damaged read/write heads, physical damage, etc., the success rate of data recovery might be lower, and in some cases, data may be unrecoverable.

Furthermore, during the data recovery process, if users continue to operate the storage device, such as restarting the computer, formatting the drive, or installing software, this could further damage the drive and render data irrecoverable. Therefore, seeking professional data recovery services promptly is crucial.

In general, leaving a faulty hard drive unattended will not make the failure worse. However, if the hard drive is exposed to a humid and dusty environment after the failure, it may further damage the drive. In such cases, there could be multiple reasons for the drive's deterioration.

If you need to recover crucial data lost from the hard drive, it is recommended to seek professional data recovery services. Professional data recovery companies have the expertise and equipment to handle the hard drive properly and recover its data to the maximum extent possible. Additionally, they can provide guidance and advice on how to handle the faulty hard drive appropriately.

Although data recovery technology is continuously evolving and improving, waiting for the faulty device to be rescued until the technology matures will not make data recovery any easier or more successful.

In fact, the longer the faulty device remains untreated, the more challenging data recovery may become. The level of damage could worsen, and the data stored on the device may further deteriorate or become lost.

Furthermore, in the case of physical failures, leaving the device untreated for an extended period may result in missing or damaged components, reducing the chances of successful recovery.

RCS Cybersecurity Center provides free diagnostic services. If your electronic storage device experiences a failure, it is recommended to send it to RCS Cybersecurity Center for diagnosis. (Please note that there is a diagnostic fee of 1,000 NTD for second-level recovery, and we apologize for any inconvenience.)

In most cases, it is not possible to specify recovering only certain files or file types to reduce the cost. When a hard drive or electronic storage device fails, all files may be affected and become inaccessible. Therefore, engineers need to perform a comprehensive scan and repair of the entire hard drive or electronic storage device.
