Ensure the power and data cables are properly and firmly seated to the drive and the motherboard. Open the drive door and use some canned air, or your breath to blow-out any dust that may have settled there. You haven't damaged the button/switch that opens and closes the door, have you?
no the button is not broken it open and close just fine. but few days latter it stops working then i have to unplug the power cord then plug it back in. then it works. but it keeps doing this over and over. im not sure why.
Maybe my psu is going ?
