In todays post, some solutions will be listed to help deal with the data loss issues properly.
This is likely to cause data loss.
If you search in Google, youll find a lot of users show interest in hard drive data recovery.

Noticing this, I think its necessary to talk about how torecover data from hard drivein different cases.
The former is called hardware failure while the latter is often called soft failure.
The practice has proved that 70% of computer failures are soft failures.

Here, Ill introduce 4 types of common reasons to lead to computer failures.
The methods for recovering lost data from hard drive will be given as well.
Partition Table Damage
Thepartition tablerecords some important information about hard disk partitions.

Here we will show you how to recover files when the partition is missing.
TheType,Filter, andSearchfeatures go a long way in simplifying file recovery during the process.
Just double-hit the file or select it and click thePreviewbutton to preview it.

Step 2:follow MiniTool Media Builder to make a bootable disk/CD/DVD easily.
If you have made a boot disk, like disconnect it from computer now.
If you have made an ISO file, yo burn it to your USB drive/CD/DVD.

Step 3:connect the bootable USB drive or CD/DVD to the computer which cant boot.
Then, restart the computer and press corresponding button to enter BIOS.
Step 4:change the boot order to make this bootable disk youve made the first boot gadget.

Save changes and exit.
Step 5:choose Partition Wizard in the MiniTool PE Loader interface.
After that, youll see the main interface of MiniTool Partition Wizard.

Step 6:snag the target disk with deleted partition and press Partition Recovery from the left pane.
Step 7:now, you should follow the Partition Recovery Wizard to finish deleted partition recovery easily.
After that, follow the on-screen instructions to upgrade it.

Step 2:Insert the USB drive into the working computer andcreate a bootable disk.
Step 3:Connect the bootable disk to the unbootable PC, thenboot from the burned bootable recovery media.
Step 4:ChooseMiniTool Power Data Recoveryin the MiniTool PE Loader interface.

After that, youll see the main interface of MiniTool Power Data Recovery.
Step 5:grab the unallocated space or lost partition according to the volume size, then click theScanbutton.
Step 7:Finally, select all required files and clickSaveto complete file recovery.
After that, it is responsible for handing over the boot right to the operating system in active partition.
This case is very similar to the first situation of partition table damage case.
The recovery process is exactly the same as said before.
To recover files deleted mistakenly from hard drive, you should do the following things.
The steps to recover data from a formatted partition are basically the same.
Well, what should you do to avoid causing secondary damage to data?
There are things that you should pay high attention to.
But unfortunately, this is completely wrong.
Secondary data damage is likely to be caused during this process.
The best reaction is to save and close pending documents, close unnecessary programs and turn off the computer.
And then search for corresponding solutions to recovering lost data from storage devices like internal external hard drive.
Writing new data into the unit which contains lost data would be very harmful.
However, in the total-512-bytes masterboot sector, MBR only takes up 446 bytes.
Another 64 bytes are given to the DPT (DiskPartition Table).
And the last two bytes are 55, AA, end mark of the partition.
FAT (File Allocation Table) Area
Locate after DBR area.
For the last cluster of a file, it has to specify that there is no successive cluster.
DIR (Directory) Area
It is next to the second FAT (FAT backup).
It records the information like the starting unit of each file in root directory and file attributes.
DATA Area
This area locates after DIR area.
It contains the real content of data on hard drive and occupies most of the hard drive space.
Conclusion
All in all, you should be careful enough when using or managing valuable data.
Once data are missing from hard drive, you have to stop what you are doing right away.
