We can divide the data-loss situation into two categories: logical data loss and physical data loss. Logical data loss means data is inaccessible due to deletion, partition corruption, partition deletion, format, reinstall, virus etc. In short, the storage media is in fine working condition but the file system is damaged or the data housed by the file system is latent or corrupt. Physical or mechanical data loss means the data is no longer accessible because the storage media is no longer operational. Hard drives may not be operational due to damage to the Printed Circuit Board, read/write head failure or platter damage. No matter what caused the data loss, we should immediately stop using the hard drive to avoid secondary damage to the data. This is important because it can affect how successful the data recovery will be.
Human error. It is revealed in a Deepspar paper that human error is accountable for at least 12% of the causes of data loss. This may include accidental deletion, partitioning, formatting or overwriting without backups etc.
Hardware failure. Hard disk drives are fragile mechanical devices. There are many moving parts running at such a high speed that any sudden impact or movement can lead to potential disaster. Aside from that, there are also chances you just have a hard disk with manufacturing defects.
Virus infection or malware. Data loss could be a side effect or main purpose of a virus infection. The battle between virus and anti-virus are constantly evolving. It is safer to make regular backups than wishing the wall holds up against the ravages.
Power failure. Power failure has two adversary effects. One is that the data in volatile memory not being saved to permanent memories. For example, you were writing a paper and the power went off before you could save your file. Another is the sudden power outage damaging hard disk. Cutting off power while the hard disk is working can result in bad sectors or damaged partition table, rendering the data inaccessible.
Most instances of hard drive failure do not destroy all of the data on the disk and much of the data on failed drives is often recoverable. The logical data loss can be easily recovered by using a data recovery software. H Data Recovery Software is recommended here as an ultimate solution to your data loss problems. It is simple and easy to use yet fully featured and powerful. Not only can it recover deleted files but also save your formatted USB disks, salvage emptied Recycle Bins or recover lost partitions. Performing data recovery with H Data Recovery Software is very simple. Just proceed as follows:
Step 1. Launch H Data Recovery Software and select a fitting recovery module. You can see the detailed description of each module by hovering your cursor over the button.
Step 2. Select the partition where your files used to be before they get deleted. If you wish to recover files on Desktop or from Recycle Bin, choose partition (C:). Click Next to start the scan process.
Step 3. When scanning is done, you will be able to see all the files that can be recovered. Check the files you wish to recover and click next to start the recovering process. If the scanning process failed to find your lost file, try our new feature “Universal Recovery”. It is a special module that scans deeper into the storage and locates all deleted files.
Immediate action leads to greater chance of a successful recovery. Meanwhile, save new files into another drive or partition in order to avoid other deleted files being overwritten.
