I am trying to download the iso of backtrack 5 r3 from my mozilla firefox. It is a 3.1GB file. Due to power failure, the download stopped some times in the middle. However, I used the mozilla's retry option to resume my download. It worked for sometimes. It stopped one more time because of power failure. And then, I tried the same mozilla retry. Unfortunately, it is not working.

So far, the download is complete upto 2.9 GB. I am able to see the partially downloaded file in my download as BT5R3-GNOME-32.iso.part. Please help me resume my download.

UPDATE 1:

I browsed a little and I found as if there is another way of resuming failed download. I decided to go with wget. I tried the following command:

wget -c http://ftp.cc.uoc.gr/mirrors/linux/backtrack/BT5R3-GNOME-32.iso -O /home/ramvignesh/Downloads/BT5R3-GNOME-32.iso.parts

But it isn't working. It just starts the download right from the beginning. The download time is horrendous for me. It says the remaining download time is 4days 11hours.
