[Bug 444818] [NEW] External disk won't spindown

[Cpp]

Public bug reported:

Binary package hint: sdparm

This has bugged me a long time on Jaunty, but it's still present on
Karmic, so it definitely needs a fix. I remember earlier versions of
Ubuntu did not have this bug. My current state is that I have done an
update to Karmic from Jaunty via update manager.

Okay, I have a number of external hard disks including MyBooks that I
connect over firewire and a WD Passport that's connected via USB. The
problem becomes apparent whenever I try to remove the disks manually. I
normally unmount them via a terminal and then spin them down before
unplugging the cable... sort of my own *safely remove* feature. I invoke
the "sdparm -C stop /dev/sdb" command as root (sudo -s) and on other
linux systems the disks spin down nicely. However for some reason that
is not the case on Jaunty/Karmic beta. the disks seem to be spinning
down for a moment, but then they always power up again and respin to
full speed like a music CD. The disk will spin down automatically after
leaving it idle for long enough.

I'm opening a new bug report because this is still present on Karmic.
