now ive been having a lot of trouble with my seagate bar sata 200gig harddrive a while ago ive started having it beep and make my mouse freeze for a bit when i was browsing stuff after testing with seatools diagnostics ive figured out that it had bad sectors which ive replaced with diagnostic program ive been running it fine for a while afterward till i started having problems with it again , so i decided to zero fill drive so i had it low formatted and reinstalled windows on it , it crashed for me after reinstalled and now that ive tried reload it with windows or erasing it and trying to load it as extra storage i get this sort of error when trying to load:
ntldr is missing
press ctrl alt delete to restart
p.S: previous diagnostics seemed to show defective sectors but now drives seems fine on diagnostic but still fails to work .
any ideas?
