    Overview of Hard Drive Recovery

    In this day and age, with the development of technology, the computer is widely used by many users. As time goes on, more and more data are saved on the hard disk when using a computer. However, data loss becomes a common phenomenon because of some factors including hardware, software, malicious/non-malicious damage. What's more, hard disk data are facing the damage from the network. Once important data on the hard drive are lost, the loss is incalculable.

    When facing these potential dangers, although careful and cautious data backup work is done, it isn't possible to provide real-time and full protection for the data. Therefore, how to effectively recover hard disk data after the destruction or data loss on the the hard drive is an important thing. Today in this post, we will introduce you some specific reasons of data loss, hard drive data recovery software and methods. So please keep reading.

    Reasons of Data Loss

    As we mentioned in the first part, the reasons causing data loss can be divided into three types: software, hardware, and network.

    s1 Software
    The cause of the software is very complex. Generally virus infection, wrong formatting, mistaken deletion and more other proper operations will lead to data loss. Usually, you probably experience the following issues: there is no file system, partition is lost, files can’t be found/accessed, and more.
    s2 Hardware
    Hard disk scratches, magnetic group damage, chips and other components burnout and suddenly power outage are common factors causing data loss in hardware.
    s3 Network
    When sharing files on network, there is a loophole which can bring virus attack and lead to data damage.

    Data loss happens in a flash, so to correctly determine the cause of the data loss is very important for data recovery. Today we will provide you particular methods about how to recover data from hard drive in software aspect.

    How to Recover Hard Disk

    When it comes to hard drive data recovery, it is important to know the particular issue of your partition. Here we will introduce you three cases in detail: partition is lost, partition exists but data loss appears, and partition is hidden.

    Case 1: Partition Is Lost

    "I have a Seagate 3TB Go Flex hard drive that I recently started using. I now pull apart my system and installed the drive internally. When I start my computer, the drive is missing. I go into Disk Management to check out what’s going on, and a message pops up asking me to initialize my drive. I choose GPT. It then shows up as unallocated. I have restarted several times and it still comes back the same. Is there any way I can recover my data from the drive? It appears that I might have to format it to get back a drive letter for it to show up. Any help will be appreciated?"

    The above example shows you a case about partition loss. Usually, partition is possible to get lost due to virus attack, improper operations, and mistaken deletion. Besides, Windows 10 update probably leads to missing partition. Moreover, disk unknown not initialized issue showing unallocated space in Disk Management is common. Once your hard disk partition gets lost, all partition data are lost. So what should you do to recover hard disk data? Is it possible to recover the lost/deleted partition?

    In fact, it is not easy to get back all partition data after partition is missing. Perhaps some of you choose to ask help for hard drive recovery service which is near you. However, hard drive recovery cost is much and it is not safe for your data privacy.

If the above method fails, you could also try to save recovered files directly to the root directory of another hard disk, D:/ for instance, or save one file at a time.

    Case 3: Partition Is Hidden

    In addition to the above two cases, perhaps you still need to do a recovery for your hard drive. During the process of using a computer, it is most likely that you find your hard drive not showing up in Windows Explorer and can't use the data on the hard disk. So how to recover data from hard disk which is not detecting? Don't be scared. Please open Windows Disk Management and check whether your partition is showing up. Usually, there are two main situations:

    • Your hard disk partition shows "unallocated". Please use MiniTool Partition Wizard to recover lost partition, just as the case 1 shows.
    • Your partition is hidden, no data loss: In this case, you still need to recover hard disk to access files on your disk.

    When there is no drive letter on your partition, you need to assign one for it. Then the partition data can be accessed in Windows Explorer. If your disk still disappears, it is most likely you have hidden this partition with a third-party tool. Please use MiniTool Partition Wizard to set the partition "unhide" by right clicking a target drive to select "Unhide Partition". Then you can access hard disk data.


    Besides, there are two other situations your disk is not detecting. Please refer to this post Quick Fix "SSD Not Showing up" in Windows 10 without Data Loss to learn more.
