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
