I have an external SATA disk in a USB-3 / eSATA docking

Other suggestions?
Have you tried just disabling spindown? (hdparm -S0 drive)
Thanks. I have now, as well as hdparm -B 255 drive.
The disk/docking station still suspends after a few minutes.
I'm ready to try recompling the kernel with CONFIG_USB_SUSPEND=n
But since
for i in /sys/bus/usb/devices/*/power/autosuspend; do echo -1 >
$i; done
also has no effect, I think it will be a waste of time.
I believe you should be doing
for i in /sys/bus/usb/devices/*/power/autosuspend_delay_ms; do echo
"-1" >$i; done
Or
for i in /sys/bus/usb/devices/*/power/control; do echo "on" >$i; done
They're supposedly equivalent (according to the kernel docs).
