The Anatomy of Hard Drive Failures

With many technological changes in the storage industry, you can see a number of choices available at your disposal. Even older drives have come across with their new high-capacity variants with improved specifications. New hard drives are more reliable than their traditional versions. However, the risk of failure still lingers if proper care is not taken timely, i.e. routine maintenance and virus scanning. Due to these risks, there are various types of hard drives failures that may be strike you at the worst time.

Logical Failures of Hard Drives 

Logical failures mean some kind of corruption has occurred to the file system of the drive. The underlying file system becomes so severely damaged that you cannot access data stored on the drive. The File Allocation Table (FAT) or Master File Table (MFT) is used to locate information on your hard drive. When the drive becomes fragmented, different pieces of information get scattered all over it making the FAT or MFT seriously entangled. Some virus programs may also target FAT, causing a range of logical errors and posing a threat to your vital data. These types of hard drive failures can be dealt with using professional data recovery software. These software use non-destructive and streamlined approach to recover all your seemingly lost information in any event of logical drive corruption.

Physical Damage to Hard Drive 

If your drive experienced a shock that has caused some damage to its internal parts, then there is a good chance it may stop working after some time. If the drive emits a clicking sound on being powered up, you can fix this by replacing its bottom board that runs the motors. However, the new board should be identical to the one being replaced. After swapping the boards, you may want to back all your important data to an external storage device to avoid any situation of permanent data loss. If the read/write heads of your drive have established contact with the surface of the platter, there is a high risk of data damage. Further, head crashes cause a lot of dust to accumulate over the platter surface. In such instances, data recovery can be done by opening the case of your drive and examining the drive for all existing problems. This job is safely carried out by professional data recovery service providers. These companies open your troubled storage media in a clean room environment and use proprietary tool to recover your valuable information.

All it takes is a bit of diligent effort on your part to perform precise recovery of lost information in any instance of physical or logical hard drive failure. By following the above recommendations, you can rest assured that your data is safe even if the disaster strikes at the worst time.

Hard Drive Failures and Data Recovery

A good deal of truth lies in the fact that hard drives fail almost intermittently. Besides pondering over the cause and the elements that lead to the disaster, one should formulate a plan to action to work around the problem quickly. Hard drive failures are classified into two broad categories: logical failures and physical failures. Logical failures are an outcome of human errors or malware attack. Such type failures are an easy bet for anyone having a do-it-yourself recovery tool on hand. On the contrary, physical failures require significant amount of effort, time, and investment.

Physical Failures and Their Types 

Physical failures eventuate when some mechanism inside of the hard drive fails. Given the number of rotations per minute the platter of the drive has to undergo, there is a fair chance that something may go awry leading to failure. Some primary types of physical failures encountered with hard drives are listed below:

Logical Board Failures 

These failures include broken power or data connectors, spindle driver chip failure, and head block pre-amplification failure. A majority of these failures require the logic board to be replaced.

Mechanical Failures 

This correlates with the failure of moving parts inside of your drive. Some typical mechanical failures include head crashes and spindle motor failure.

Firmware Corruption 

This happens when the firmware built into your hard drive has become outdated. You need to update this firmware to resolve the issue.

Most of the time, physical failures are easily visible and they can be sensed observing various symptoms. A physically damaged drive is not recognized by Windows Disk Management, Device Manager, or system BIOS. You may occasionally notice a clicking sound emitted by the drive when accessed. In other cases, your hard drive may tend to lock up quite frequently after specific intervals of time. This most likely happens when you are anticipating a failure in near future.

Overcoming Data Loss in Event of Physical Failures 

When a physical failure occurs, you need to follow preventive measures to make sure your data is still safe on the affected media. The success of any sort of recovery attempt rests on the initial course of action you take after facing the disaster. You need to ensure that the damaged drive is no more used for reading, writing, or copying data. This keeps you from overwriting your original files placed on the hard drive.
