thanks.
I assume there should be an equal sign after the "if", right?
Anyway:
- shouldn't this be done several times, to make sure that whatever was
in the free space really is unrecoverable?
- apart from that, probably it's a mix of typos and English not being
my native language, but honestly I don't understand the last two
lines of your answer, that is the part after "as the same":
creates a file with random-stuff until the disk is full, syncs it
really to the disk and removes the file as the same with dd
if=/dev/zero will zerofill free space to make it possible shink thin
provisioned virtual-disks as example
may I ask you to rephrase them, please?
