Subject: RE: USB spindown (was RE: Feature Request: USB HDD only Custom Ro m.)
From: Joel Wiramu Pauling (

You can set hd parameters at boot, and hdparm works fine over usb
I´m not sure about your spindown option, but you can use hdparm . I know
that setting dma modes with hdparm over usb works fine (use it for
external dvd burner). So it should work fine with the archos.

Kind regards
