On a MB (GA/nforce560) I used a Seagate 7200.11 (SATA) and a fresh install of

Because of the Firmware bug of the Harddisc I decided to replace the HDD with
another one.

This means that you've set the HD_IDLE_TIMEOUT_SECONDS to a value high
enough to prevent the disk from sleeping at all. I'd have hoped the
opposite. If you don't hear the disk heads unparking, then laptop mode
doesn't fix anything but has just the side-effect of keeping your disk
up. Please report
@Milan: Enabled laptop mode, rebooted. Disk access continues, though not
as predictable. BUT, now I don't hear the annoying 'disk-unpark' noise,
or whatever you want to call it. So I guess it's a partial fix...
