ok, there is no way to delete the hdd password. it can be reset with a master password. to create a master password you need to at least post the hdd serial number which is displayed in the 'error code' (e.g. #ABCDEFGH12-595B where ABCDEFGH12 is the hdd serial number).
well, as I said... wait for the guyy to give you master password or buy one or buy a new hdd.
