7 Main Causes for Hard Drive Corruption

It is not a rare phenomenon that people failed to enter the system when starting computer. The reasons responsible for that disaster are multifarious. Even a slight impact on hard disk platter or a wrong operation could lead to a corrupted internal hard disk.

Here, we summarized 7 popular causes for a corrupted hard drive. Please get to know them one by one.

Reason 1 – Physical Damage


Physical damage, also known as hardware failure, includes the following types:
  • Overheating;
  • Read/write head crash;
  • Cracked or poor-contact data line;
  • Scratch on magnetic platters;
  • Short circuit in the control circuit board, etc.

The data lost due to those kinds of reasons can hardly be recovered. You have no choice but to turn to professionals for data recovery from physically damaged HDD.

Reason 2 – Hard Drive Aging

Every hard disk is built with a certain service life. The usual argument is that the theoretical life of a mechanical hard disk is probably more than 30,000 hours. If the hard disk is working continuously (for example, in Web server), then you can kiss goodbye to your industrious hard disk after about 3 years.

Note: please don't worry too much; the service life of hard disk used by ordinary computer users could last for about 6 to 10 years.


Reason 3 – File System Damage


File system is used by operating system to define the method for organizing files on storage device. To be specific, it is like a gateway to access data saved on hard disk partitions. If the file system on internal hard disk is unfortunately damaged somehow, the disk may become inaccessible and the computer may fail to start.

Reason 4 – Virus Attack

If a computer is attacked by virus, the necessary boot files stored in internal hard disk may be destroyed or deleted, leading to boot failure. Meanwhile, the useful data or the whole partition may also be deleted by the virus.

Reason 5 – Boot Sector Corruption

Boot sector is the first sector of hard disk; it is used to load processor control and then transfer it to the operating system. Once boot sector is damaged, users will not be able to enter the computer and access any data saved in internal hard disk.

Reason 6 – Software Conflict


All kinds of programs we installed on our computer currently may not able to be fully compatible with each other, so software conflicts happen now and then to lead to unexpected computer shutdown and cause internal hard drive corruption.

Reason 7 – Human Error


Since not all users are professional in computer using and file managing (the fact is more than half of the users are not a good hard disk manager and they're not experienced), they tend to make some mistakes when computer is running, resulting in hard disk crash.

Be aware of those causes and try to stay away from them!

How to Choose a Good Hard Drive


In this part, we'll walk you through some common purchasing skills here. The following aspects could decide the overall performance of a hard disk and customer satisfaction:
  • Price;
  • Interface;
  • Capacity;
  • Speed;
  • Stability;
  • Cache;
  • After-sale service.

Skill 1 – Compare the Price


Whenever we want to buy a thing, quality and price comes first into our consideration. No matter how good the stuff is in quality, if the price is too high to afford, most of us will give up the idea of bring it home.

On the contrary, given that the quality of a thing is not so satisfactory, but as long as it has an appealing price, some people would buy it even if they don't need it currently.

Skill 2 – Pay Attention to Price

We think it's not so necessary to talk much about capacity so much since "the bigger the better" is always true in terms of this aspect. By the way, with the fast development of technology, the capacity of hard disk has been increased a lot when there's no big change in price (see picture).

Skill 3 – Look at the Interface


In terms of the hard disk interface, the most widely used one is SATA (Serial ATA put forward by Intel). The famous IDE hard disk is out of date. As for another hard disk interface specification – SCSI, though it owns many advantages which IDE can't be compared to, it is seldom used among ordinary users due to its expensive price (which is decided by the high production cost).

Look at this page to know difference between SATA & IDE.

Skill 4 – Get to Know Cache

There's also not much to talk about when it comes to hard disk cache. Why? That is simply because most of the hard drives are built with a 2GB cache; only some advanced hard drives adopt a 4MB cache.

Data recovery from corrupted internal hard disk 14

In fact, large cache is a good feature for hard disk since it can improve disk performance significantly, but it has one shortcoming – the price is relatively high. Yet, you can choose an appropriate cache by following your own financial situation.

Skill 5 – Check the Speed

It is easy to understand that a 7200 rpm hard disk is better than a 5400 rpm hard disk in performance. Just because of this, two hard disks with the same capacity could have difference price. Under the condition that the price difference can be accepted, we suggest users to choose a hard drive with fast rotational speed.

Skill 6 – Take Stability into Consideration

Unquestionably, strong stability is the thing everyone wants to pursue. The stability determines how long your hard disk's service life is in a way and it reflects whether it was a right choice to buy your hard disk at your price. Therefore, it's safer to avoid the outdated or the newest hard disk.

Skill 7 – Don't Forget about After-sales Service

This is an aspect that nearly all people will take into consideration before they buy a product, especially when this product is very expensive. As you know, hard disk is always working at a fast speed as long as your computer is running.

Data recovery from corrupted internal hard disk 15

But it turns out that hard disk is actually very fragile and could be broken at any moment. No one would like to see his important data saved on hard disk gone, so after-sales service and quality assurance are two vital factors that would change users mind when they're selecting hard disk.

In order to avoid the troublesome and annoying data recovery from corrupted internal hard disk, users should hurry to roll up their sleeves to pick out a hard disk with high cost performance.
