Sooner or later. To see if it's the drive, you put in a new one and see if the problem goes away.
I have a pavilion zt1170 laptop. It just decided one day not to start-up. It keeps asking me how to start-up...HD,Floppy,CD or Lan. Press on HD and nothing. In Bios, HD=0GB. Suddenly after 100 ons and offs HD decided to start. If I reboot system HD will boot but if I shutdown completly HD won't start-up until the next 100 times of on-off. Is the HD the problem? will it die completly soon?
