When you face external drive failure and are going to recover data, a very important step is creating a disk image file – sector-by-sector copy of the original disk. Let’s discuss why it is important.
Let’s imagine a situation where your external disk has many bad sectors and you cannot access data stored on it. If you try to use such a disk in data recovery, there is a chance to get more bad sectors resulting in less data recovered in the best case, or no data at all in the worst case. The same is true for other disk malfunctions.
To create a disk image file you need to use special software. Most data recovery tools allow to create disk image files. Below you can find the detailed instructions on how to create disk images in ReclaiMe File Recovery:
You can put the original disk aside and work only with the disk image file. Note that the disk image created by ReclaiMe is not bound exclusively to ReclaiMe — you can load it to any data recovery program capable of working with disk image files.
