Well, I did. And it does IDLE IMMEDIATE with UNLOAD:

shambhala:~> hdparm -I /dev/sda | grep IDLE
           *    IDLE_IMMEDIATE with UNLOAD
shambhala:~> smartctl -a /dev/sda | grep Load_Cycle
193 Load_Cycle_Count        0x0032   200   200   000    Old_age   Always   =
   =20
=2D       73
shambhala:~> smartctl -a /dev/sda | grep Load_Cycle
193 Load_Cycle_Count        0x0032   200   200   000    Old_age   Always   =
   =20
=2D       73
shambhala:~> hdparm --idle-unload /dev/sda

/dev/sda:
 issuing idle_immediate_unload command
shambhala:~> smartctl -a /dev/sda | grep Load_Cycle
193 Load_Cycle_Count        0x0032   200   200   000    Old_age   Always   =
   =20
=2D       74

;)

I wasn't sure at first, cause I do not hear *any* head movements of the=20
drive. It appears to be quite fast as well.

=46irst I thought the drive is quite noisy, but I compared with my Hitachi=
=20
160 GB and it made the same noise. Thats just the 5400 rpm sound I guess=20
and I do not hear it when the ThinkPad fan is on. But no sound of head=20
movements whatsoever.

Thats the drive:

shambhala:~> hdparm -I /dev/sda | head -11

/dev/sda:

ATA device, with non-removable media
        Model Number:       WDC WD3200BEVE-00A0HT0                 =20
        Serial Number:      WD-WX80EC9SW890
        Firmware Revision:  11.01A11
        Transport:          Serial, SATA 1.0a, SATA II Extensions, SATA=20
Rev 2.5
Standards:
        Supported: 8 7 6 5=20
        Likely used: 8

AFAIR it has the same firmware revision than the one mentioned in the Wiki.

Before:

shambhala:~/alt-neu-platte> egrep "(home$|/$)" df-hT-alt.txt
/dev/sda1     ext4     14G   13G  724M  95% /
/dev/sda5     ext4    131G  129G  1,8G  99% /home

After:

shambhala:~> df -hT / /home
Dateisystem   Typ     Size  Used Avail Use% Eingeh=E4ngt auf
/dev/dm-0     ext4     20G   13G  6,7G  65% /
/dev/dm-1     ext4    197G  127G   69G  65% /home

And about 78 GB left in the volume group.

So me is happy now ;-).

If I remember I will enter the drive to the wiki tomorrow.

Ciao,
