Hard disk drive is the basic storage media of computer. It is a non-volatile and random access device for digital data. The basic anatomy of hard drive includes platters, spindle, spindle motor, read/write head, and head actuator. However, hard disk is not only used as storage media but some parts of it are fully dedicated to operating system. Therefore, hard disk can be divided into various logical storage units abbreviated as partitions. These partitions need a method to organize and store data in human readable form called as file system. Some major file systems of Windows operating system are FAT, NTFS, and exFAT.
A hard drive can become corrupt or get damaged at any time without any sign or any warning. That's probably one of the harshest truths about laptops and PCs. Not only is that, the same goes for external hard drives too. So if you think that an external hard drive is the safest place to store a backup, you may want to reconsider. It wouldn't be wrong to say that currently, probably the safest place to store a backup would be the cloud since any mechanical hard drive is subjected to wear and tear over time if not anything else. And thus, all of us should be aware of why it can happen and how to deal with it on our own end before we panic and run to a service center. So go through this write-up thoroughly and keep the pointers in mind for reference if the need arises (God forbid)!
Possible causes of hard drive failure or loss of data can be as follows:-
There could be several reasons behind a failed hard drive. From mishandling to mechanical damage, it could be anything including the following:
To rectify this issue and recover photos from hard drive you need Photo recovery software.
Before proceeding to the ways to recover photos from hard drive, let us also have a look at the kinds of damage or corruption possible to a hard drive.
Kinds of damage to hard drive
Knowing what kind of damage or corruption has struck the hard drive can help you in diagnosing the level of destruction caused. It can also help you in choosing the right way to repair it and salvaging the photos on it.
There are primarily 2 ways in which a hard drive can be corrupt or damaged – Mechanical failure or Logical failure.
If you inadvertently drop your hard drive leading to breakage of its internal parts, that means your hard drive has suffered mechanical damage. Most hard drives that are not SSDs, store and retrieve data by writing and reading from magnetic platters that are stacked vertically. Sudden jerks like dropping the hard drive could break the platters causing what is referred to mechanical damage.
When you connect a hard drive that have broken parts to a laptop or PC, it usually makes a clicking sound as it tries to access the files on it. Such a sound is a clear giveaway of its truly dead state. So if you hear that sound you should accept one good and one bad news. Good – your data is still intact and can very well be recovered. Bad – you'll have to take it to a service center or have experts over to examine it; and such services can cost quite a lot.
If on connecting a failed hard drive to your laptop or PC you don't hear any clicking sound and the drive doesn't boot up too, it might be an indicator of a logical failure. In such a case, the data on the drive is there for sure, but there's some issue that is preventing your hard drive from accessing it or from accessing its system files. If you act quickly and take a few steps, you can very well redeem all data on it intact.
How to recover photo from hard drive that has failed
Here's what you can do if you find that you're internal or external hard drive has suffered logical damage.
To sum it up
A failed hard drive usually has some unmistakable warning signs such as sudden computer freezes or OS crashes followed by the "blue screen of death". If such a thing happens, don't ignore it thinking you'll backup the second time. There might not be a second time. So keep a backup right away to be absolutely sure of your data's safety.
