Unfortunately, most home users, and many business users, do not back up their systems. Moreover, many small businesses have older back-up procedures that are often ineffective for recovering files.
Of course, you can run down to your neighborhood electronics store and purchase a replacement drive for your computer, but what about your data on the failed hard drive? How important was it? Did you save it or back it up?
What to do:
If you need to recover data on the hard drive, the first thing to do is avoid trying to reboot or doing anything that involves the drive. Doing so can actually do more damage to your data.
The only irreversible data loss is caused by overwriting bits, physical damage to the drive platters or destruction of the magnetization of the platters, which seldom happens in the real world. In the majority of cases, the malfunction is caused by a damaged circuit board, failure of a mechanical component and crash of internal software system track or firmware.
In the case of actual hard drive failure, only a data recovery professional can get your data back. And the fact that you cannot access your data through your operating system does not necessarily mean that your data is lost.
As a "rule of thumb," if you hear a clicking sound emitting from your hard drive, or if the computer's S.M.A.R.T. function indicates an error during the boot process, something is wrong. You should immediately stop using the hard drive in order to avoid causing further damage and, potentially, rendering the information on the hard drive unrecoverable.
After receiving your failed hard drive, a data recovery specialist's first step will be to try and save an image of the damaged drive onto another drive. This image drive, not the actual damaged drive, is where the data recovery specialist will try to recover the lost data.
The next step in the imaging process is to determine if the hard-drive failure was an actual malfunction, a system corruption or a system track issue.
System corruption and system track issues are normally fixed by using a specialist's data recovery software. System corruption or system track recoveries do not require processing in a clean room environment.
Unfortunately, damage to a drive's circuit board or failure of the head drives is not uncommon. In each of these failures, a data recovery specialist should work on the system only in a clean room environment. There, the specialist can substitute parts such as drive electronics, internal components, read/write arms, writing/reading heads, spindle motors or spindle bearings from a donor drive in order to gain access to the data on the failed hard drive. In most cases, the data recovery specialist is able to retrieve and return the lost data.

Data loss is a tragedy that every computer user has to suffer from at least once a couple of years. This issue is frightening and disgusting. In this article, we are going to take a look at 5 common causes of data loss and the precautions that you should take.
1. Deletion of files by mistake
Today, most people lose their important data due to their own mistakes. For instance, they delete their important files by mistake and they have no backups of the files. Without an iota of doubt, we delete many files every day on our computers.
Precaution: it's better if you create a backup of your important files. This way you can recover the files quickly in case you delete them by mistake.
2. Viruses Attacks
Virus and malware attacks is another common problems these days. And most viruses tend to corrupt our important files. As long as you are connected to the web, you can't avoid the risk.
Precaution: if you want to prevent the data loss by malware and viruses, make sure you invest in a powerful antivirus to protect your computer against virus and malware attacks. The antivirus app will give you a warning each time a suspicious activity is going to happen on your computer due to a virus.
3. Mechanical Issues
The failure of a hard drive is an annoying issue. Of all the hard drive issues, the mechanical issue is the most common. Typically, the issue is associated with the spindle or the head of the drive. If this happens, you have no choice but to repair the damaged components. However, don't make the mistake of doing it yourself.
Precaution: instead of opening up the drive yourself, we suggest that you take proper care. For instance, you should never drop the drive or hit it hard against a solid object. This can help you prevent a lot of mechanical issues associated with your computer hard drive.
4. Sudden Power Outages
You may be familiar with the term "power failure" in the world of computers. You may have experienced power outages. In case of a power failure, you may lose some important data, especially if the light goes out while you are trying to modify or compose a file. Without any doubt, the file may get corrupted.
Precaution: if you want to prevent the data loss against a power outage, you may want to make use of a surge protector. You can also use a battery or some other type of Uninterrupted Power Supply.
5. Water Damage
Apart from the factors given above, your hard drive may also get damaged if exposed to water. For instance, if you spill some liquid on your computer by mistake, your hard drive may get damaged. In another scenario, you may end up dropping your computer into water.
Precaution: if you want to prevent water damage, we suggest that you try to reform yourself first. This means that you should correct your bad habits. Try to keep your computer away from water.
So, these are a few common causes of computer data loss and the precautions that you may want to take.
