    Dear all,

    In next days I've to change Cloudron server to a new one.

    How I can delete data of the old one, before ISP take back the bare metal server?

    Thank's a lot!

          @p44 yes, i imagine there will be how-to's to this, so just ask the search engine of your choice.

          No you would not need to create a filesystem for it as dd is writing direct to the partition.

                  Depending on the provider, they already zero things out. For example, DO does this. Of course, you have to trust your provider.
