So I tested esata on a siis pcie card with a 750G Seagate Freeagent Pro
drive and it does work - until the drive falls into powersave mode
after being idle for a little while. :(  (I had the drive on 1394
before on another box where it was able to recover from this condition,
but not on usb or esata - and the drive's 1394 interface died a while
ago and also esata is faster anyway...)

 And now I came across this patch for the linux ata driver:
	http://git.kernel.org/?p=linux/kernel/git/jgarzik/libata-dev.git;a=commitdiff;h=169439c2e35f01e7832a9b4fc8a7446980c3d593;hp=1e999736cafdffc374f22eed37b291129ef82e4e

 So my question is, could the same be done in our ata code?
I have a slight :) hope it would help this drive too at least as it
does seem to work on Linux...

 Thanx,
	Juergen
