+IDE warm-plug HOWTO
+===================
+
+To warm-plug devices on a port 'idex'::
+
+ # echo -n "1" > /sys/class/ide_port/idex/delete_devices
+
+unplug old device(s) and plug new device(s)::
+
+ # echo -n "1" > /sys/class/ide_port/idex/scan
+
+done
+
+NOTE: please make sure that partitions are unmounted and that there are
+no other active references to devices before doing "delete_devices" step,
+also do not attempt "scan" step on devices currently in use -- otherwise
+results may be unpredictable and lead to data loss if you're unlucky
