Hi
if you have bought a new laptop or a new smartphone, and on the old laptop or smartphone still has some data on it, but which are not really important: Deletes her all the data on the old devices before you stowed somewhere or leave her the stuff just on it until the device probably no longer works?
Everything at factory settings
I do not delete them individually, but everything to factory settings. So you can be sure that normal people will not get your data.
With the old laptop / PC you should overwrite the hard disk with zeros. This works best with Darik's Boot and Nuke. Here is the download of the ISO: https://sourceforge.net/...o/download Then flick the ISO with this tool https://www.balena.io/...io/etcher/ on an empty formatted USB stick. When the stick has been created, simply boot the stick.
Simply reset smartphones / tablets to factory settings.
