No matter you’re using a desktop or a laptop, there’s an internal hard disk built-in your computer when you bought it. Since different computers’ configuration is different and users’ operations are not all the same, the internal hard disk corrupted sometimes due to poor hardware quality or wrong operations.

Part 1: Is Data Recovery from Corrupted Internal Hard Disk Possible

Sometimes, your hard drive is clicking before the corruption, but in some other cases, the disk just corrupts without giving a sign.

Once your internal hard disk is corrupted, you must be depressed, right? You will be blocked out from the system, losing all entries to files saved in the internal drive. I know countless cases in which people are dying to know the most effective solution to data recovery from corrupted internal hard disk.

Obviously, how to recover data from a corrupted internal hard disk is a task that is more formidable than getting back data from a removable drive. But please stay calm; this isn’t a problem that can’t be fixed. I will provide solutions for both desktop users and laptop users to recover data from the damaged internal hard drive.

First of all, I suggest you try to restart the computer to have a try after encountering internal hard disk crash; that works sometimes. Even if some data are lost due to the corruption, you can recover them easily in this case.

However, in many cases, you may end up in failure, stuck in an infinite loop or in one stage of a startup. In this case, you should follow the tutorial given below to rescue your data.

Note: Please don’t worry too much; you’ve got a great chance to regain all the lost data as long as the accident is not caused by physical damage of hard disk.

Part 2: How to Recover Data from a Corrupted Internal Hard Disk

I suggest you turn to Power Data Recovery Boot Disk to scan & recover data from the internal disk without booting into Windows:

You should make a Boot Disk via using the Snap-in WinPE Bootable Builder provided by some editions of Power Data Recovery (click to see edition comparison to find out). Then, use the boot disk to enter your computer. And finally, you can recover your data.

How to make a Boot Disk?

Step 1: insert the USB disk to another computer (which works well) and run MiniTool Power Data Recovery on it. Then, register it and click on the “Bootable Media” button in the lower left corner.

Click on Bootable Media

Step 2: please click on the “WinPE-based media with MiniTool plug-in”.

Step 3: choose a media destination. Here, I’m taking USB Flash Disk as an example. After clicking on it, you’ll see a prompt, informing you that data on the disk will be destroyed. Click “Yes” to confirm.

What if you choose a wrong USB disk as the destination? Please start free USB data recovery ASAP!

Step 4: wait patiently when the bootable USB disk is building. Then, click on the “Finish” button when this process is completed.

Now, you have a bootable USB disk; you should eject it from the computer safely.

How to boot from this disk?

Step 1: insert the bootable USB disk to the computer which has a corrupted internal hard disk. Then, start the computer to enter the BIOS.

Step 2: adjust the boot order – making removable devices (in which the USB drive is included) to be the first boot device. Now, save changes and exit.

Step 3: then, you’ll see two windows in order, in which you need to confirm the screen resolution and the action of launching MiniTool Power Data Recovery.

Step 4: at last, you should click on the first option “MiniTool Power Data Recovery” to open the software.

How to recover data with the boot disk?

Step 1: in the main interface of the software, you should scan your corrupted internal hard disk to find the files you need. In this step, you have 2 choices.

  1. Select “This PC” and choose the specific partition.
  2. Select “Hard Disk Drive” and choose the internal disk as a whole.

select This PC or Hard Disk Drive

Step 2: also, you are provided with 2 choices in this step.

  1. Double click on the partition/disk you want to choose to start scan directly.
  2. Press the “Scan” button in the lower right corner to start the scan.

Step 3: more and more files will be found during the scan. You should browse them carefully to figure out whether the software has found what you need.

Step 4: check the files you need one by one and click on the “Save” button in the lower right corner. Then, you should select a directory to save those files and click on the “OK” button to confirm your selection.

save files you need

Warning: You should save the checked files to a removable disk with enough free space because your internal hard disk is corrupted and the computer won’t boot without a bootable disk. If you forget to connect a removable disk in advance, you can close the directory setting window and click on the “Save” button again to refresh the list.

This method is useful when you need to recover data from hard disk without OS.

Situation 2: Finish Hard Drive Data Recovery When Computer Can Be Restarted

I suggest you adopt the Free Edition of Power Data Recovery to scan & recover your lost data if you are in face of the following cases.

  • Case 1: as I have said before, you can try to restart your computer right after it corrupted. In a few cases, people succeed – they can enter computer after restarting. And suddenly, they find some of the files saved in internal hard disk disappeared.
  • Case 2: if the corrupted internal hard disk is placed in a desktop, it is relatively flexible. You can take it out from the computer case gently and then connect it to another computer as a secondary hard drive.
Note: In the above cases, it’s pretty much easy to recover data from the corrupted internal hard disk. I strongly recommend that you do the recovery immediately. Then, backup all important files you need on the disk to be well prepared for another round of hard drive crash.

Yes, you can recover data even after a hard drive crash.

How to recover data from crashed hard disk with free software:

Step 1: download and install the MiniTool Power Data Recovery Free Edition.

Step 2: choose to run this software immediately from the last window of installation wizard or right click on the icon from the desktop.

click on the icon from the desktop

Step 3: you should finish step 1 to step 4 mentioned in the “How to recover data with the boot disk” part of situation 1.

The only difference is that you can choose to save the recovered files to both a removable disk (recommend) and the internal hard disk itself (as long as you can confirm that you have found back all the files you need from the corrupted disk; otherwise, secondary damage may be brought and you’ll lose the files remaining on the disk forever).

Note: The free edition only allows you to recover no more than 1GB of files from your internal hard disk. To recover more, you should save the scan result manually; then, buy a license to upgrade the free software and load manually saved scan result to continue data recovery.

This method is also useful when you want to recover data from a corrupted/dead external hard disk.

It is not a rare phenomenon that people failed to enter the system when starting the 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, I mainly summarize 7 popular causes of a corrupted hard disk. Please get to know them one by one.

One: file system damage

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

Two: virus attack

If a computer is attacked by a virus, the necessary boot files stored in the 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.

I feel glad to share solutions with users to help them recover files deleted by virus attack quickly and safely.

Can you recover files deleted by virus attack? Definitely, you can. Here are several solutions to help you recover files quickly and safely.

Three: boot sector corruption

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

Four: software conflict

All kinds of programs you 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.

Five: human error

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

Six: 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 hard disk drive.

Seven: 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: But you don’t need to worry too much; the service life of the hard disk used by ordinary computer users could last for about 6 to 10 years.

Please be aware of those causes and try your best to stay away from them!
