If you have a removable disk, like a USB memory stick or an external hard disk, you may sometimes wish to completely remove all of its files and folders. You can do this by formatting the disk — this deletes all of the files on the disk and leaves it empty.
Open Disks from the Activities overview.
Select the disk you want to wipe from the list of storage devices on the left.
Assicurarsi di avere selezionato il disco giusto. Se è stato scelto quello sbagliato, tutti i file presenti saranno persi per sempre.
In the toolbar underneath the Volumes section, click the menu button. Then click Format Partition….
In the window that pops up, choose a file system Type for the disk.
If you use the disk on Windows and Mac OS computers in addition to Linux computers, choose FAT. If you only use it on Windows, NTFS may be a better option. A brief description of the file system type will be presented as a label.
Give the disk a name and click Next to continue and show a confirmation window. Check the details carefully, and click Format to wipe the disk.
Once the formatting has finished, click the eject icon to safely remove the disk. It should now be blank and ready to use again.
Formattare un disco non è un modo completamente sicuro per eliminare tutti i dati. Un disco formattato all'apparenza non contiene file, ma è possibile ripristinarli con software speciali. Se è necessario eliminare in modo sicuro i file, usare uno strumento a riga di comando come shred.
