Subject: Re: automatic HD spinoff in USB Mode
From: Andrew Jamieson (ajamiesn_at_optusnet.com.au)
Date: 2002-11-17


There are two ways you can do this. You could set a HDD spin down time in
your OS (Windows allows this, I would imagine Your Favourite OS would do the
same), which should work, although I have never tried it; or with the
Recorder, the chip can take control of the HDD from the USB-IDE chip, and it
could then spin down the drive. Of course, to do this, the controller would
probably need to know when the transfer was finished, and I'm not sure how
this could be done. I guess the controller could assume the drive is
inactive if the contents of the buffer dont change for blah minutes .....
