Well, thanks for the answer but this not a chipset issue, IMHO, is a
software issue if that ATA command for HDD is relayed over all the
mass-storage and usb drivers and if the whole chain cope with it and
don't barf.
Best regards,

There is no way to tell for certain if attempts to spin-down will work with
your particular enclosures. Chipsets (and their capabilities) vary widely.

Hi all,
We want to use some standard USB 2.0 enclosures containing a 3.5" HDD
for some backup purposes, the ideea was that those guys could stay
attached and eventally moved to some other machine and so on, so far
everything is OK, there is only one problem I'd like to know of:
The bloody HDDs gets HOT, like in extremely hot :(, because somehow
seem that they never spin down, I know about hdparam and the stuff that
I could try to spin it down, but ( and there is a big but) will that
stuff work nondistructively on USB mass storage devices as above, will
they be able to be spinned down without losing data, getting disconneted
from the USB bus and other horrors ( and of course, restarted again :) ???
If somebody could help with a definite answer on that issue, eventually
with some hdparm switches TESTED on such an external disk it will make
me very happy.
Thank you for your time and season greetings,
Mircea Ciocan
