Let’s start today’s cartoon by the end: “Always have more than one copy of your important files.” If the protagonist of our story had applied this moral, we would have nothing to tell, because it probably would not have brought a damaged hard drive to our data recovery centre.
But you already know that there is not always a backup … or maybe it does exist but it is not up to date … or bad luck is concentrated: the copy disk and the original fail at the same time!
So, in case you want to take your files from one hard drive to another, our recommendation is: “Do not move your files, copy them!”.
Perhaps this advice seems exaggerated to those who are in favour of moving the files from one unit to another, to avoid the work of manually deleting the originals. In any case, we believe that telling our experience can be useful; From there, each one decides what level of security they want to apply when managing their files.
After seeing the variety of incidents that end up requiring data recovery, we believe that it is much more prudent to copy the files to their new destination instead of moving them. Once copied, we can verify if the copy process has worked correctly. Only then – and always expecting that we have also made a backup – it will be safe to erase the original files.
Also, keep in mind that if the target disk is external, it is much more exposed to accidents. And of course, for a hit to cause data loss, it does not have to be as catastrophic as the blow of our story.

Possibilities of data recovery
“How could it have been damaged by falling from such a small distance?”, Some of the clients tell us when they ask for data recovery, while they explain that the damaged disk “only” travelled one or two centimetres before the blow. Yes, any fall however small can seriously affect the hard drive, especially if it is working and the heads rub the magnetic plates while they spin at full speed.
In fact, in the real case that inspired this cartoon, the external hard drive to which the files had been moved was badly damaged and only a partial recovery would be possible. Fortunately, the client had taken the precaution of not doing any other operation with the original disk deleted. Thanks to this measure, the data was intact in the physical medium of the disk, and in the laboratory, it was possible to recover all the files.
