hdparm problem

[Chris Murphy]

sudo hdparm --user-master u --security-set-pass Eins /dev/sdX

sudo time hdparm --user-master u --security-erase Eins /dev/sdX
OR
sudo time hdparm --user-master u --security-erase-enhanced Eins /dev/sdX


Just copy and paste it. Two commands are needed. Just two. Not three. Not one.
