I built a new PC some days ago, and everything seems perfect, except that the 1 TB HDD I cloned from my old 500 GB HDD is making a deep weird sound. First of all, every time I access the disk, I hear a deep sound, and when the PC is turning on, I hear some clicking (the rapid clicking is my mouse, I'm opening and closing folders to trigger the vibrating deep weird sound I'm describing). I'm using this 1TB disk for data mainly (I use a SSD as the OS).
As background information, the disk is a seagate barracuda 7200 rpm which was RMAd and replaced with a refurbished one. Maybe the refurbished disks make these noises? should I worry about my data? (although the disk is working normal and passed a seagatetools short generic test? Thanks!
PS: I recorded the sounds, just click on the links. Thanks
UPDATE: I finally reduced the possibilities of this humming noise to vibration. Concluded this by taking the HDD out and placing it in a mat as suggested by @Synetech. The vibration can be also because I changed the surface where the computer is. Back then I had it in a carpet, and know I have it in a wooden-surface (aka computer desk).

Based on the description and tests, it sounds like that particular model of drive just happens to vibrate more than average (high vibration is normal for a 10,000RPM drive, but even a 7,200 can be kind of noisy).
Try mounting it with some rubber grommets/shims (or something) to absorb the vibration instead of passing it through to the case. Also, if the case has hard-plastic feet, replace them with rubber ones or put the whole thing on a soft surface (keeping airflow in mind). If the sound and vibration are reduced to nominal levels, then it is probably not something to be worried about (only annoyed at).
If you are concerned about the health of the drive, check the SMART data (e.g. with SpeedFan or SeaTools), to see if there are any warnings about its actual health since any delays in spin up and such would be logged there; though it is probably going to check out as okay.
(Based on the following description from someone else with this issue, it may be due to a slight misalignment.)
