Technology does not always work as one expects. Even though you try the devices with extreme care, things break at the moment when it rages most. External storage drives, such as SD cards, USBs or hard drivesThey are one of those devices that if damaged can get you into serious problems, make you lose work material, study or personal files. And not only that, but they can also become unusable for all kinds of reasons.
For try to recover the data you have to resort to third-party programs and be very patient (or very lucky depending on the case). Depending on the degree of damage you can get results or not; It is not the same that the card or USB does not react because it has been extracted without doing it in safe mode or because when going to transfer the files to the computer there has been a power cut and the unit has suffered a serious error. The examples already cited are some of the most common, but the famous ‘I have no idea what happened, the last time I used it was fine’ also often occurs.
Be that as it may, the first thing to bring to life an SD card, USB or any other drive that fails is try to save the data; Whether you succeed or not, the next step is format: the formatting will return it to its factory state and even if you do not recover the information, at least you will be able to continue using it without problems every two by three – unless some internal physical component has been damaged with some fall, for example, in which case you will have to take it to a specialist and wait for it to be fixed.
Recover files with DiskDigger
There are certain computer programs to recover lost information. Recuva y Disk Drill are two of the most used, as we teach you in this guide, but today we are going to use DiskDigger (Windows and Linux; if you use Mac, go to the previous link and use Disk Drill): in this way, if with one of these options you don’t find the files, you always have a plan B to see if it works more.
The first thing you should do is download the program. When you have it, unzip the ZIP file you have obtained and double click on the .exe file. Insert the SD card, USB or other type of storage in its corresponding slot on the computer.
With the program open, select the damaged drive and click on the ‘Next’ button (‘Next’ if it comes in English). In the new screen you will get two options: a quick search used especially when recovering files deleted manually (the first) and a deep search which is used for damaged devices (the second). Select the second option and click on ‘Next’ or ‘Next’ again.
Next, the program will show you all file types of which you have found references on your card or USB. These types of files are selected automatically, but you can uncheck them all by clicking on the ‘Do not select’ option or ‘Select none’ and manually select those types that correspond to the damaged information (if you had Word documents, JPG images, .mp4 videos, etc.). If you don’t know much about computer science, you can always leave everything on so as not to get confused, but the results can be more chaotic. Click on ‘Next’ or ‘Next’ again when you have it.
The process will take a few minutes, depending on how many file types you have selected and how much movement the drive has had. When finished, you will have a list with all the files you have managed to recover: go through the preview one by one (the files are not shown with their original name) and as you find any of the damaged ones, select them and click on ‘Save files as’, or ‘Recover selected files’, to save it on your computer.
Format the card or drive
At this point, we hope that you have been able to recover all the files. Whether you have succeeded or not, you have to format the SD card or storage drive:format the SD card or storage drive a deep format recovers it as long as it is due to a bug that can be solved (an error in the reader or in a physical component would not be fixed in this way).
To format the drive in Windows, open your ‘File Browser’ from your computer and locate it. Right click on it and select ‘Format’. Choose the format type (NTFS is for Windows only, FAT32 is universal) and Uncheck the ‘Quick Format’ option.uncheck the option ‘Quick format’ Accept and wait for the process to finish to eject your card or drive.
To do the same in Mac you have to click on the magnifying glass icon located at the top right of your screen and search ‘Disk Utility’ (you write it and give ‘Intro’ to open automatically). Select your external drive and click ‘Delete’. Give it a name, select the format to be compatible with other operating systems) and in ‘Security options’ choose the ‘depth’ of the formatting (more or less fast or effective). Accept and click on ‘Delete’ to complete the process.
