Hard Disk make a sound on Startup & shutdown

[g_goyal2000]

Hi.
I recently got my Samsung SP0802N 80 GB IDE/PATA hard disk replaced with a Samsung SP0822N (yup, SP0822N) 80 GB IDE/PATA hard disk.
The problem is, when I power on the computer & while POST, the hard disk makes a single 'tuck' noise which also occurs when the computer is turned off.
My previous SP0802N didn't make this noise.
What does this mean? Is it normal?
Does this mean that the given hard disk is refurbished/repaired?

Did u send ur prev HDD to service center for repairs>If yes then the HDD u hav received is a refurbished one.As far the sound is concerned i think its the head comming in contact with the platter.

Well, actually they replaced it.
They told me that no HDD maker repairs it's HDD's here in India.
They all go outside for repairs.

Damn idiots don't even offer Data Recovery here in India.
Have to goto local Data Recovery centres.

Anyway, they said they won't give me a new HDD as replacement, but a refurbished one. Well, that means a repaired one. I think I got that one.

Would be going tomorrow or next week for replacement. Let's see what happens.

It's pretty late to post a reply.
But now after so long, I seem to have found a reason.
It's my SMPS.
The click noise is coming due to faulty SMPS. How? I don't know?
I recently got my SMPS repaired after which the click noise stopped.
And my SMPS was the reason that my HDD had crashed.
