after droping my  inspirion laptop and getting a blue screen, it will not boot up.  the dell screen starts to load then it says "A disk error has occurred" ctrl alt delete to restart.

I do that and it does the same thing.  I then ran the self diagnostic test and got the results

 Error Code: 0142

Msg: Error code 2000-0142

Hard Drive 1- Self test unsuccessful

Status:79

What does all this mean?? Will i need a new hard drive? and if so is what is currently on the drive lost?

any help would be great!! Thanks!!
