^on my old p4 system the hardrive is dying (906 SMART errors) and i never have issues with crashing, and have only locked up once
I'm not sure but the hdd is full of big movies and softwares.they are not broken.rarely I cant open some video and photo files because they are broken in hdd.chdsk screen appears frequently at startup suggest me to check files in c: d:. it finds some errors, delete some entries etc. if I skip that screen, browser crashes and freezing are more frequent if I permit it to repair hdd.it stands for 1 or 2 hours and ask me to repair hdd after freezing again.so I think my hdd is dying.
-sometimes I delete a movie file permanently and download a new one with torrent into the same disk.when I try to open this new file, it interestingly find and open a deleted file which I erased two months ago !
