I recently bought a new HP laptop, and I've learned my lesson. I'll never buy another HP laptop again- they are filled with bloatware and run slow and hot. I've already had my stock harddrive fail on me as well. The HP updater randomly fails receiving and installing updates to its shitty software that is full with security holes (see the recent problems with its quicklaunch bar). It's just terrible all around. Don't buy an HP.
My previous laptop was a Toshiba - and it was much much better. My next laptop will be a Toshiba. The HD never failed on my Toshiba (still runs after 4 years) and the only reason I got rid of it was because the power cord was poorly designed and eventually crapped out. I heard they still have this problem- and I haven't done any research on them lately. Good luck with whatever decision you do make.
