I recently brought a Seagate Barracuda 7200.7 SATA - ST3200822AS

However after the PC has been Idle(not being used for a while)/or switched on, and I start using my PC again my hard drive makes a noise, it only seems like a seek noise and its pretty loud. This can happen when i open Windows Explorer or any program that is installed.

After using my PC for say 5-10 the noise kind of fades away and is not heard again, if it is its only under a huge load and is very brief.

Is this problem because my hard drive has to like warm up or something?

I have ran a few hard drive checking programs and everything has came up fine, I have my hard drive in 3 partitions, the last one was for movie rips etc. This partition (last one) did come up with a error at one stage but after a reformat it has been fine since...

So does anyone know if there is a problem with my drive?

Is there a program I can use to test it besides seagate tools?

Thanks for any help...
