My Hard Drive Is Failing I Need A Replacement But I Am Not Sure What The Actual Size I Would Really Need
Hp Won't Answer My Question Unless I Pay Them $20 For One Time Tech Support

I Want To Try To Repair It Myself, Last Time I Took A Laptop To The Computer Repair Place He Didn't Know Anything About Factory Images or How to Use Them.
 So I'm Not Really Going To Trust Him With This.
I know it's Size Is In Inch's But I'm Not Really Sure
I'm Sorry I'm New At This Any Help Would Def Be More Than Welcomed
Thank you

when i boot it up it says Hard Drive intimate failure and asks me to back up everything.
it was fine last night but i went to boot it up today and it kept restarting i did system repair a few times it finally did start but started saying that.
the warranty has expired hp wont even answer my question about hard drive size
so i searched the net for the hard drive intimate failure to figure out what it is.

it was fine last night  i shut it down like normal.

That's the built-in hard drive S.M.A.R.T. monitoring, it's definitely going bad & can fail at any time.

It's a 2.5" notebook drive, probably SATA interface, but let's be sure:

You will need the Recovery CD's that came with it.  If you can backup all your important stuff, & then install Macrium Reflect to create an image of the entire hard drive, that will be a lot easier than starting from scratch with the Recovery CD's.
