I recently bought two 750gb Samsung Spinpoint hard drives which I have installed into my Dell PowerEdge SC440 server. The drives are mirrored using software raid. I am running Debian Etch.
I've noticed that when I shut down the computer, there is a single click from each drive. It is quite noticeable above the normal operating noise and the noise from the case fans etc. I haven't experienced any problems with them otherwise.
Given that I get this from both drives, I think I'd be very unlucky if they were both faulty.
However, I was wondering whether there might be any BIOS settings or Debian/RAID configuration that might be the problem?
I'm not sure, but I have the same clicking noise with my 250gb WDs in RAID. Was wondering the same thing, anyone have any info? I hope they're not going bad
Yes, it is the drive heads retracting into their parked position. No worries.

though that sound is very worrying, it is indeed healthy. it is controlled by software, eg windows xp doesn't click the hdd during shutdown, vista does.
there is also a downside of this: it takes more time to shutdown, and fire up the hdd at the next boot.
