Random mechanical "Clicks" and Write Error Rate (S.M.A.R.T.) increasing

Hello, everyone!
I decided to write on here as I have been shadowing the forums for a while and found invaluable advice quite often. I am sure someone will be able to assist me.

After 4 years, my Pavilion dv6000's 250GB WD hard drive began showing corrupted sectors. Being paranoid, I had backed my data up on several externals, and was even able to recover most of the contents even with a S.M.A.R.T. drive health of 58% and dropping.

However, seeing as I use my computer for pretty much everything, instead of buying a replacement HDD, I decided to purchase a Sony Vaio E1511, with a Seagate hard drive (ST750LM022).

I have been using this computer for 4 days, and I've noticed the following issues:

- once in a while, particularly when talking on Skype, I will hear a mechanical "click" coming from the hard drive, at totally random moments.

- i've come to associate that "click" with an increase of Write Error Rate/Multizone Error rate. The computer is barely a week old, and yet, my raw score is at 82 (I am attaching the full diagnostic at the bottom of my message)

- My Spin-Up time is reported by several pieces of S.M.A.R.T. software as being sub-par (a score of 89%).

Now, should I be concerned? Every time this "click" happens, the Write Error Rate increases by one.

Thanks in advance,
Erik
