Tips to Better Perform Data Recovery
Data Recovery Software is very helpful when files are accidentally deleted, files lost after memory card or hard drive reformat, files lost for unknown reasons. However, it is not guarnatee that lost data can be recovered. In this article, I will discuss about the main reasons that cause data recovery tools failed to recover lost data, and tips to improve the chance to retrieve lost data.
Reason 1, lost data are overwritten by new data
Most users may be not aware that continue using of the storage device like memory card or hard drive may cause lost data unrecoverable.
When data is lost, the space used to store data are normally not erased, the system will only mark the space as free, so that when new files are saved, the space can be used to save the new files.
When new file is saved, it could be saved to othe free space, but it could use partial or all of lost data's space also. Once the space is overwritten, it will be very hard for data recovery software to recover lost data.
The tip is, stop using the computer, or memory card, when you realize that the data is lost and you want to recover it. Then download some data recovery tool and scan and recover lost data.
Reason 2, storage device not accessible
Data recovery software may be able to recover data when files are deleted, or device is formatted. But when storage deivce is not accessible, asks for formatting when you try to open it, or even it's physically damaged, not detected at all by Computer.
Users often feel panic and don't know what to do when the deivce asks for formatting when tries to open it. The best way to recover data is to format the device, and then use professional data recovery tool to scan and retrieve the data.
