Bug Description

Notebook model: HP Pavillion dv2172ea http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00786030&lc=en&cc=us&dlc=en&product=3279896&jumpid=reg_R1002_USEN

HDD model: Seagate ST9120821AS http://www.seagate.com/pdf/datasheet/disc/ds_momentus5400.2_120gb.pdf

Ubuntu version: 6.10 (final version, fresh install)

When shutting down the system, I can hear the bad sound of the HDD being halted unsafely (because the power is being cut while the disk's head isn't in park position yet).
When shutting down WindowsXP the HDD halts with no bad sound.

This is bad, as halting the HDD in this manner causes very fast wear of the drive.

That's normally not a problem, as modern hard disks park the head automatically when the power is cut. Have you experienced data corruption or similar symptoms, at all? Do the filesystems on the drive get checked (fsck) regularly during bootup? I'd suggest installing smartmontools in order to find out if there's anything wrong with the disk.

I repeat: shutting down with WindowsXP is clean and doesn't produce any
sounds, the harddrive spins down silently.

This means that using Ubuntu, the power is cut before the head is
automatically parked so the drive has to perform emergency head park
(which emits this noise, and wears the drive more quickly).

Can someone who knows the shutdown procedure of Edgy Eft please give
some help?

Thanks
