Hi all, After I followed the steps to connect the serial interface and supply power to the HDD. The only thing on hyperterminal I am getting is RequestResumeSaveSmartFrame RequestResumeSaveSmartFrame RequestResumeSaveSmartFrame RequestResumeSaveSmartFrame RequestResumeSaveSmartFrame Some one on the other web said this is normal, but I simply can not enter any command to the HDD. Can any one help here? Thanks a lot!
