[Bug 300805] [NEW] usb hard drive does not enter standby mode before shutdown

[Vu Ngoc San]

Public bug reported:

I'm testing the new intrepid (kubuntu)

I have a USB external hard drive connected to my laptop, and I think
linux is supposed to make hard drives go to sleep (standby mode) before
turning the power off. Apparently it does not for the USB drive, since I
can hear an unpleasant 'click' when the laptop powers off.

(It's the same click when you turn off a laptop by pressing the power
button for a long time, in case everything hangs)

I'm quite afraid it could damage the hard drive if repeated frequently.

Of course I could do sleep the HD manually by hdparm -Y /dev/sdb but
it's impossible for me because I would like to boot ubuntu on this
volume, so the hard drive is needed until the last operation.

Ubuntu 8.10
linux-image-generic:
  Installé : 2.6.27.7.11
