One of the problems that can happen to us when we work with computers is to lose some document with which we were working. After a few days we tried to recover it and we did not find it. The normal thing in these cases is that it went to the recycling bin due to an oversight and, at a certain time, the paper bin was emptied. This is where if we do not have a backup and the document is important, we can panic.
But the truth is that we have different options to try to recover my data. The first thing we have to consider is how an operating system deletes the files. In this case, all computer systems behave in a similar way.
If we talk about a common erasure – the document that is deleted from the bin – what Windows does is mark the space occupied by that file on the disk as available space. In this way other files can occupy it and the system can write in these sectors of the disk.
Different issue is a secure deletion. For this, a specific program is needed that, in addition to freeing the space, worries about overwriting it, according to the chosen algorithm, a specific number of times. An example of this type of programs is the Eraser , highly recommended when what we want to eliminate is financial information or personal data, for example.
Here it does not matter so much if we talk about a traditional hard drive, which magnetically records information or an SSD disk that does it electronically. These last ones incorporate the equipment of the last generation like the Lenovo Yoga 910 since when not having mechanical components, they have faster times in reading and writing. This implies that the performance of the team is better, although at the time of recovering the deleted files their behaviour is similar.
Where was your file?
Therefore one of the issues to take into account when recovering an erased file is how long ago that file was deleted. As more time has passed since it was removed, it is more likely that the occupied space was used to locate a new one.
You also have to keep in mind where we kept the file. For example, if our document was on a Dropbox virtual hard disk, it is important to know that we have a recycle bin available if we access the web service, where we could find the deleted file. From here he could also recover. Another possible solution is if the virtual hard disk was synchronized on another computer, which is not connected to the Internet and has not yet synchronized the changes. The ideal, in this case, is to start it without a network connection to copy the file to another location.
If our file was located in Documents, Music, Images, Videos and Desktop and OneDrive files offline, it could be recovered if we had Windows File History enabled, even if we had not connected the network drive of copies, and that keeps a version in the hard disk cache waiting for the unit to reconnect.
In this case, more than recovering a file, it is useful to recover a version of the file. That is when we have made a series of changes and we want to return to an earlier version but we are not sure of everything that we have changed. It is activated through Settings> Updates and Security> Backup and it is necessary to have an external disk connected to make the copy.
There are laboratories specialized in recovery, but because of the cost involved, it is very high. They are also effective, especially in the event that a hard drive has been physically damaged, not so much for intentional deletion of a disk.
Options to recover files deleted by mistake
But if all this fails we have to look in the free space of our computer with a program specialized in recovering this type of files. Everyone works more or less in the same way.
These programs have a filter that we have to complete in order to make the search faster. You can specify the name of the file, if we know the path where it was located, the type of file lost, be it text, image or video, for example. And also the approximate date on which it has been lost. With all these elements performs the search in this free space and tells us if we have the option to recover it or not.
These are some of the alternatives that we have available:
Recuva has a free version that will be more than enough for most users. It marks us with a simple colour code, green, yellow or red if the file is recoverable or not. Then we just have to indicate in what location we want to save it, where it is always advisable to do it on an external disk.
GetDataBack is another very interesting alternative. In this case, it opens a folder tree according to what is available in our team. It shows us the files that we have available within each folder and that is recoverable or not. This helps a lot if we know where we kept the lost document. It has a free version that allows us to check if you can recover the file. But then, if we want to do it, we have to acquire the product license.
PhotoRec is a very interesting free alternative to recover image files or videos. Also from external memories or SD cards from where we have deleted them. Maybe it does not have the friendliest interface, but it’s very effective.
If after passing these programs we have not found our files we can give them practically for lost.
Lenovo Yoga 910 Glass
When in doubt and to avoid problems, it is better to bet on a quality device, such as the Lenovo Yoga 910 Glass. In this case, the hard disk is of the SSD type and also uses the PCIe connection, the same used by graphics cards, for example. This connection interface makes it can be up to 27 times faster than if it were connected by SATA III.
This guarantees us a spectacular reading and writing speed for a high-end laptop. It is also complemented by its clock-type hinge, which allows the screen to rotate 360 degrees. The most advanced models come with a 4K screen, a resolution of 3840 x 2160 that makes its 13.3 “screen one of its biggest attractions.
The aluminium housing ensures that the heat generated by its processors, Intel Core i7-7500U dissipates properly. In this sense, your SSD also generates less heat than a traditional hard drive. It also protects our laptop from bumps and falls. All accompanied by 8 GB of DDR4 RAM and a battery that guarantees us between 10 or 15 hours of use, more than enough to spend all day away from home.
