HOSTS file gone! :o

I decided to back up my HOSTS file to a cd.
What happened is:
1) I select my hosts file and click send to--> D:\ (CD drive)
2) Unfortunately, the CD-R disc was dirty and could not be read by the drive. So I took it out and put in another blank CD-R disc.
3) I then deleted the temporary files in the cd burning folder, it went to the recycle bin. Was I correct to do this?
4) Instead of emptying the recycle bin, I used Eraser to erase it. And when I went to check again, my HOSTS file is 0kb!

Somehow my problem is exactly the same as the one described at the Eraser forums... http://www.cipherserver.com/phpbb2/viewtopic.php?p=6788&sid=2bd71d6b0113fb06ff7541158d622c58

How am I going to recover my original HOSTS file back? I need help. Seems like a silly mistake of mine.

 

The original file reads like this:

=====[begin]=====
# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

127.0.0.1 localhost
