Try:
sudo hdparm -d1 /deb/hdb
The "sudo" command lets you run a command using the Superuser authority, otherwise known in Unix/Linux as the "root" user account.
To open a terminal window with superuser authority, you can type:
sudo su
and you can even create a "root" account password with:
sudo passwd
