Hard Disk Failures, Data Recovery, and Subsequent Solutions!

In a world that is driven by data, we know how much data is worth and how much losing essential data can cost anyone, from individuals to organizations. Well, information is sensitive and very powerful if used rightly, inviting a lot of threats from various sources.

Data recovery comes in very handy and helps to solve inaccessible, lost, and corrupted data. It is nothing but the process of restoring lost data. Data that has been lost, deleted accidentally, made inaccessible or damaged can be restored to a desktop, laptop, server, or an external storage source. Generally, when data is deleted, it still remains in the physical storage. The data recovery software is logical technique and hardware tools are used to recover this data from the physical storage of the system.

The Hard disk is a key device for storing data. Very often, data loss happens due to the failure of a hard drive.

Let us take a look at the types of failures that a hard disk may encounter and what their symptoms are:

  • Electrical Failures:

The PCB is a crucial component that acts kind of like a middleman, controlling, coordinating, and communicating the acts of reading and writing data between the system and the hard disk. If the PCB somehow gets damaged due to power spikes or power surges, there’s no other way to access the data, and it will be lost. This is a common failure scenario.

The lost data can be recovered easily as well as using data recovery services. Some of the symptoms that your hard disk might encounter a failure could be because of PCB inside the hard disk. If you might have heard any clicking noise issue in your hard disk then it would be issue of PCB failure. Basic symptoms of electronic failure and hard disk are knocking issue, no power PCB hit up and it could be because of power down after a certain time period.

 

  • Mechanical Failure:

Mechanical failures do not occur very often unless there has been an impact and wear and tear on the hard disk. In that case, several types of mechanical faults such as spindle motor gets stuck in the hard disk, head damage and the head is stuck on the platter. When such faults occur, a very low sound from the hard disk occur, that we have to very carefully listen to identify the mechanical fault. Some of the symptoms of mechanical failure include grinding and clicking sounds, completely quiet in case of motor freeze and unusual noises as the disk is powered up.

 

  • Logical failure:

Logical failures refer to any other kind of failure that is non-physical. It can be the easiest or the hardest recovery job depending on the causes behind the logical failure. A few cases of logical failure include accidental formatting, software bugs, accidental deletion, virus infection, malware, file corruption, bad sectors and file system corruption, and a lot more.

 

  • Firmware failure:

Firmware is a software used for low-level disk testing and other functions that are responsible for the proper functioning of the hard disk. It is generally only accessible to the manufacturers of hard drives and hard disk repair and data recovery companies like Data Empires.

 

Without the proper code due to firmware failure, there can be no communication between the hard disk and the system. If somehow the area of the platter containing the firmware code gets corrupted, the drive will fail even though all electrical and mechanical components are working just fine. Some symptoms are that the system does not recognize the drive, recognized wrongly, detection in bios but no detection in disk management, system hanging, hard disk initialization issue and it freezes during booting up.

 

  • Bad Platter Area:

Over time the platter surface may suffer due to wear and tear, or there could be manufacturing defects or the head may crash, or it could be tracking errors as well. In that case, inaccessible data blocks or sectors can be seen during writing and reading.

Data is lost, and the amount of data that can be recovered depending on the situation. Some of the symptoms of a bad platter area include sluggish performance, constant cyclic redundancy (CRC), inability to access files and folders that are visible.

 

  • Complex Failure Model:

Usually, hard disks don’t fail in a single mode of attempt. A combination of various failure modes commonly causes failures. It is essential to understand the modes of failure and then carry on with the repair and data recovery process.

So, these are the common types of hard disk failures that can lead to the loss of valuable data. For all kinds of Hard disk data recovery services, no matter what the breakdown is, you can get in touch with at Data Empires and avail the best-in-class data recovery and repair services.
