I have a number of USB hard drives connected to a Linux PC. They

It's as though they stopped spinning when not accessed for a while.

The only way I found to get around it was to reboot. Changing

See if
echo "-1" >/sys/module/usbcore/parameters/autosuspend helps fix this.

Unfortunately, /sys/module/usbcore/parameters/autosuspend doesn't
exist in my Slackware 12.1 box, running a 2.6.24.5 kernel.
