File copy to USB appears to finish too fast

I made a script for Xfce Generic Monitor applet that tells me how much data is written to usb disks. Runs periodically every few seconds. With Mate Desktop, I think Command applet can be set to run this script. At least it tells you when the drive is in idle state or writing. Along with some indication about how much data was written since the drive was plugged in.

[code]#!/bin/bash

if ls -l /dev/disk/by-path/usb &>/dev/null; then

USB_DET=($(ls -l /dev/disk/by-path/*usb* | grep -v "part" | awk '{print $NF}' | awk -F "/" '{print $NF}' | sort))

for usb in "${USB_DET[@]}"
do
	if [ $(awk "{ print \$9 }" /sys/block/$usb/stat) -gt 0 ]
	then
		sector_size=$(cat /sys/block/$usb/queue/hw_sector_size)

		DATA_WRITTEN=$(awk '{load = $7*sector/1000/1000
					printf "%.1f", load}'  sector="$sector_size" /sys/block/$usb/stat)
    		printf "%s: %s%s " "$usb" "$DATA_WRITTEN" "MiB"
	else
		printf "%s: %s " "$usb" "idle"
	fi
done

else
echo “None”
