[reboot]

Hi all.
By mistake I clear all SMART data
Can you tell me how to restore or set new SMART attribute step by step in terminal, or recommend easy(or not) software for SMART editing.
My HDD is Seagate 7200.12 ST3500418AS. 500Gb.
This attribute I wish to restore or set new.
-- S.M.A.R.T. --
[04] Start/Stop Count
[09] Power-On Hours
[0C] Power Cycle Count

I have PL2303 USB To RS232 TTL Converter.

Sorry for my English. Its not my native language.
