Taken from man hdparm:
-Y Force an IDE drive to immediately enter the lowest power
consumption sleep mode, causing it to shut down completely. A hard
or soft reset is required before the drive can be accessed again
(the Linux IDE driver will automatically handle issuing a reset
if/when needed). The current power mode status can be checked
using the -C flag.
So it looks like hdparm assumes that the kernel IDE layer is able to
wake the drive up. Perhaps the SATA layer can't handle it yet? I will
ask upstream, but it seems like a kernel issue at firts look.
Take care,
