I have several new 2.5" 500GB Hitachi HTS725050A7E630 and HTS727550A9E364. They make the "clink" parking noise, in XP they do it constantly, in Win7 less so but it's still very annoying. In Linux they don't do it at all.

Something in the Windows OS keeps accessing the disks even when they're idle, even if formatted ext4. I've checked APM with Hitachi FTOOL and they're all set for max performance xFE (254). I've disabled "superfetch" service in Win7 but they're still clicking every few seconds.

Any ideas?

If you're running any software (eg, SpeedFan, AIDA) that monitors the disk temperature (via SMART), it will spin up the disks even when they are idle.

I tried several times to get XP to spin down my idle disks, and eventually gave up. In my situation, it was best to let them spin all the time.

Thank you, I'm not running Speedfan or AIDA, but maybe Win7 keeps checking on the disks' status via SMART ? If so, I'd like to know how to stop it. I certainly don't think there's anything wrong with the HDs, the Z7K500 is the kickass-est 2.5" out there.

Have a look in the BIOS, often there's a setting there to disable SMART. Win 7 might give up checking if it thinks the drives aren't SMART-capable.

Windows can definitely spin down drives.
SMART monitoring would indeed be a prime suspect if drives containing no readable partitions are kept from idling as well. Otherwise I'd be looking at indexing and page files rather than Superfetch.
Microsoft has software you can use to log what accesses the drive (I don't know if it'll catch SMART though): www.sysinternals.com

Sorry for reviving an old thread, but FWIW I was able to solve the problem described by OP by running two instances of Speedfan.
