Last month 10, our customer service received a phone call from Mr. Wang saying that he was an employee of a wedding company. He took a few photos of customers before, and then when he was retouching the pictures on the computer, the computer suddenly crashed and could not be turned on normally. The system crashed after maintenance. Although the computer can be turned on normally after being repaired, the files on the computer are gone, and because of work needs, the photos on the SD card were deleted after being imported into the computer, and colleagues also took the SD card away. He searched a lot of data recovery software online, but he couldn't recover the photos on his previous computer. A couple of days later, the client asked for photos, and he found us under the recommendation of an anxious friend.
Our customer service first calmed Mr. Wang's mood, and then learned that the previous photos were kept in the mechanical hard disk, and after the computer was repaired, it was not operated on the computer. Then, under the patient guidance of our customer service, Mr. Wang first downloaded our easy-to-me data recovery software, scanned the partition of the lost photos, and found that the lost photos could be previewed normally. That's easy. Being able to preview the file normally means that the disk data is not overwritten. Click Restore directly, select a location to save the file, and then continue. Here, our customer service specially reminds Mr. Wang not to save the data back to the source disk, so as not to overwrite the lost data and cause the data to be incomplete.
In the end, Mr. Wang successfully recovered the lost photos and avoided disputes with customers. It took only 30 minutes from finding us to recovering the data, and Mr. Wang was also very satisfied with the data recovery.
Friendly reminder:
1. If files are lost due to system crash, you should use data recovery tools in time. Before confirming data recovery, remember not to write new data to the source disk, so as not to overwrite the lost data and make the data completely unrecoverable.
2. Install genuine security software, and regularly kill viruses to prevent the file system from being destroyed.
3. Make regular backups of important data to avoid data loss without precautions.
Little knowledge:
Fine-tuning function of solid state hard disk
Trim function is a function of most SSD solid state drives, and it is ATA command. When the system confirms that SSD supports Trim, when deleting data, the hard disk deletion command is not notified, but the volume bitmap is used to remember that the data here has been deleted. So as to realize faster data processing.
On the mechanical hard disk, when writing data, Windows will inform the hard disk to erase the previous data before writing new data to the disk. When deleting data, Windows will only mark it here, indicating that there should be nothing here, and it will not be deleted until the data is actually written, and the marking action will remain in the disk cache until the disk is idle. So the disk needs more time to perform the above operations, and the speed will be slower.
When Windows discovers and recognizes the Trim function of SSD, it does not inform the hard disk deletion instruction, but only uses the volume bitmap to remember that the data here has been deleted. Then, when writing data, because the data stored in the NAND flash memory is pure digital, new data can be directly written into the deleted block in the snapshot according to the situation of the volume bitmap, without taking time to erase the original data.
So friends can install the system on the solid-state hard disk and save the files on the mechanical hard disk.
