Why would Linux be waking up every 5 to 10 seconds to write to the

- Seagate 320gig SATA
- XFS filesystem, relatime mount option enabled
- link_power_management_policy set to min_power
- vm.dirty_writeback_centisecs is set to 1500
I even unmounted /boot (default ext3) but that did not change anything.
Every 5 to 10 seconds I see the HDD light flash and sometimes I hear a
very faint "beeping" like the drive is waking up or powering off,
whichever it is doing.
Try tweaking your hdparm settings.
Adding this to your rc.local might help:
/sbin/hdparm -S 255 /dev/sda
/sbin/hdparm -B 255 /dev/sda
