Hard Drive Data Recovery: Imagine that you are working on an important project for your business. You and your team can smell the finish line after weeks and weeks of intense work. Then the unthinkable happens. A hard drive malfunction causes you to lose all your work. You hope that you will restore your work with a simple reboot, and you panic when it does not work. This situation happens too often for businesses that rely on computers for work. Fortunately, hard drive data recovery is possible, if you have the necessary tools and IT professionals. Here are four things you need to know about hard drive data recovery, if you ever come across this scenario.
How Does Hard Drive Data Recovery work?
Many people think that the file has disappeared from their computer as soon as they remove it from the garbage can. This is not true. When you click delete in a file, you delete only the identifying tokens that help your computer find the file during the user’s request. This allows your hard drive to use the space that was once used by the source file, although it still technically exists.
There are two ways to recover a deleted file. The first is to use free software to recover data on your hard drive. Although free software can work in some cases, they often have limitations that simply do not work at the enterprise level.
The second option is to try to restore the file manually. The first thing you do is create a new file with the same exact name as the permanently deleted file. Then right-click on this file. In Windows, you will see the possibility of restoring previous versions. Click the latest version and the file must be restored.
What to do when hard drive data recovery does not work
Sometimes the hard drive fails completely and is no longer detected by the software for hard drive data recovery. In this case, you do not have many options, but there is one thing that you should try. Check the cables that physically connect the hard drive to the CPU motherboard.
To do this, first make sure that everything is off and off. Then discharge the static electricity of your body to avoid shock. Open the back of your processor with a screwdriver and check the following connections:
SATA power connector
4-pin Molex power connector
SATA interface cable
After you have checked these connections, close the processor and reboot the computer. If you still can not access your information, the last option is to contact a data recovery specialist.
How to prevent the need to restore data on the hard disk
Most of those who are looking for software to hard drive data recovery are in an emergency situation. They find themselves in a panic and eventually buy software or hire a professional, not performing due diligence.
The best solution to this scenario is to have a data processing policy that will help you avoid it in the first place.
Make sure that all of your most important data is backed up daily. Keep a backup copy on your primary network to ensure its security in the event of a network failure. Do not deviate from the data policy and do not make an example of those employees who do it.
When to destroy data
Sometimes, for one reason or another, you need to destroy the data, not restore it. Many companies participate in electronic recycling programs when they modernize their equipment. It’s great for the environment, but it can be a nightmare when it comes to data security. It is known that identity thieves are targeting hard drives that are casually discarded to find out if there is any personal information for recovery.
The Ministry of Defense reacted to the growth of cyber attacks by adopting protocols that all data cleansing specialists should perform. Two professionals are used to clean your hard drive. The first is a three-pass rewrite. The technician makes the first pass, which changes all the data to the “0” symbols. The second pass changes all data to the characters “1”, and the final pass to all symbols. This process makes the data completely illegible.
More sensitive data passes through a seven-pass rewrite that follows this sequence:
- 0” character
- “1” character
- Random character
- Second random character
- “0” character
- “1” character
- Random character
Remember these four things to ensure the security of your data customers and employees.
