[TOPIC] Accidentally erased important data ! HDD and SSD data recovery method

Many people have experience of losing data due to unexpected troubles or accidentally erasing important photos and files while using a personal computer. It is most important to always keep a backup in case of an HDD and SSD failure or trouble, however some of you might not have a backup in case of sudden trouble. If you want to recover some data that you have deleted, you may recover the internal data. This content explains how to recover an HDD and SSD data.

・1. Recover data using software

・1-1. HDD data recovery
Let’s take Windows 10 as an example to see how to recover if you have formatted or accidentally deleted important data. If your computer can be started and the HDD can be recognized from the Explorer screen, you can try data recovery using the officially sold “Windows 10 data recovery software”. There are free software with similar functions, but the genuine product is safer.

Execute the data recovery software wizard after starting your computer
Select the disk on which the file was saved (local disk, etc.) and start scanning
When the scan is finished, the files will be displayed, so select the one you want to recover and press the recovery or similar button.
[Point] Save the recovered data on an external HDD or memory card, not in the original location where there is a risk of damage.

・1-2. SSD data recovery
In the case of HDDs, the data is always in the place where the magnetic disk was written, however an SSD is not. This is because SSD, which is a collection of flash memory, distributes data in order for the controller to evenly read and write each memory, and places it in a different location from the original data. Therefore, it can be said that SSDs data recovery is more difficult than HDDs. However, like an HDD, an SSD has data recovery software, so that if you use a software, there is no big difference from HDD data recovery in terms of software operation.
As with an HDD and an SSD, if there is a possibility that the product itself has a problem, you need to ask a specialist.

・2. Ask a professional contractor
The safest and most reliable way of recovering your data is to ask a data recovery specialist. If data has disappeared, or if you simply accidentally erased it, there is a high possibility that it can be recovered with data recovery software. However, in the unlikely event that there is a problem with the physical failure of an HDD or SSD itself, energizing the product is not recommendable and you should stop trying to recover yourself. Talk to a specialist to see if your data can be recovered.

・3. To increase the probability of data recovery
If you want to recover a file that has been erased, the probability that it can be recovered varies depending on how much you wrote to the drive from the time of erasing. Whether you use the software or ask a specialist, it is better to try to recover as soon as possible without writing.

・4. Conclusion
Since data recovery using software is not so difficult, so you may feel free to try it. However, this method works on only deleted files. When an HDD or SSD cannot be read in earnest, it becomes difficult to determine whether the cause is a logical failure or a physical failure. As mentioned above, if you can’t decide for yourself, it is better to ask a professional contractor as soon as possible.
