Bootcamp backup deletes external NTFS HDD

Question

maybe someone can help:
I wanted      (because OSX Lion does not allow to run Bootcamp with WIN XP) to      remove the Bootcamp-Partion on my MAC drive, but save it on an      external disk for backup. 
    For that reason I      have connected an external WIN formatted NTFS-USB Drive to my      MacbookPro, and tried to copy the Bootcamp partition to this Drive      - in addition to the data, which were already on that drive (and      this data are very very important films I made in the past).
    I had done this with the following procedre:
    "Instructions
    1 .Plug in an      external hard drive to copy the Boot Camp partition. Make sure the      drive contains an empty partition of equal or larger size.
    2. Open the      "Utilities" folder inside the "Applications" folder, then run      "Terminal."
    3 .Type the      following command and then press "Enter":
    diskutil list
    This displays a      partition table with four columns. Locate the "Boot Camp"      partition, and make a note of its identifier. This will be similar      to "disk0s3." Make a note of the identifier of the external drive      partition.
    4. Type the      following command to unmount the Boot Camp partition:
    diskutil unmount      /dev/disk0s3
    Replace "disk0s3"      with your Boot Camp partition identifier.
    5. Type the      following command to unmount the external backup drive partition:
    diskutil unmount      /dev/disk1s1
    Replace "disk1s1"      with your external drive partition identifier.
    6. Type the      following command to clone the Boot Camp partition to the external      drive:
    sudo dd      if=/dev/disk0s3 of=/dev/disk1s1 bs=1024
    Replace "disk0s3"      with your Boot Camp partition identifier, and "disk1s1" with the      external drive partition identifier.
    Unfortunately I      did not know the result of this procedure:
      Now I had killed my whole external drive (1TB), overwritten with      this Bootcamp-Mount.
      It seems, that there is now on the drive only one      "Bootcamp-partition (or Bootcamp-mount with 20 GB). I can see no      data on the drive with WIN XP.
Does anone have any suggestion I could do, to remove      the Bootcamp-mount from the drive and rescue the old data bringing them up again?
    XP-Drive manager sees the drive with 931GB (one parttion) but no    bootsector or data (suggests a formatting).
    Is there any idea for me?
    Thanks in advance,

Well I finally gave in and formatted the external drives to HTFS+, so now I can read and write on them from anywhere on my home network. But this does mean I cant unplug them and use then with a windows machine directly. Or I have to buy paragon HTFS+ for windows and have that every time with me on a USB drive been allowed to install it (for example on one of the the computer at my school). It feels to me like this just a marketing scheme to spend more money. I mean how am I as end user suppose to know that after I upgrade my OS I am not able to use external NTFS Hard drives on my network. No one in the store when I was buying a mac told me: "Hey when you buy a external drive do format it to HTFS+ immediately or else you could have problems. I mean apple knows that except maybe for a few brands the most used format for external drives is NTFS. There should have been at least a warring before installing Mountain Lion. The best scenario would have been if it just worked. Ok enough of my complaining, its just that this has been really frustrating. I mean to backup 3tb is about 20 hours and then copy it back to the drive is about 13. Am still copying as I write this.
But anyway that's one problem solved. Wake on LAN still have no luck with that one. Well I got a work around but its not ideal. For me setting the Display Sleep to 3 hours works, because my iMac 24 and my main PC are nest to each other. But I guess for people that need this for remote servers even that wont work. O btw maybe this helps a few people, Teamviewer seems to be able to wake him up too.
