OMG, what?!

You didn't check what device it was first? :-o

You didn't look to see if it had been registered by the kernel?

You didn't check to see if it was formatted? Or see what kind of
partition table it had? Or whether it had partitions?

:-o

That is... _SUICIDAL_, Marco!

Anyway, AFTER you do them, you need a partition. You can't just format
a whole drive!

Google this stuff FIRST, dude!

Marco, man, we were on a distro project together something like 15 or
20 years ago, maybe more. I *know* you know this stuff. Or knew it. If
you are not SURE that you remember, don't just go blundering in
blindly! Google it! CHECK!
