Try with
xplorer360 instead:
http://forums.xbox-scene.com/index.php?s=&...t&p=4669512. My
hdtool.exe actually reports the security status of the hdd from within Windows as well.
THIS worked!
Thousand thankyous ldotsfan, you saved my day!
What I did was simply just play the music like I always did and hotswap this into a usb hdd casing while inside windows 7 x64 (and then power it up), I told xplorer360 to check the drives and it instantly found partitions 0 1 2 3 and 4.
Right now I am backing up the whole drive.
For some reason there was a gta3.img on one partition, I guess the previous owner had his fingers on this one

So, if you have a usb hdd casing, follow this post if you have some mysterious problems with the linux-boot method like I had.
And a simple guide for USB hdd case swap, Using a regular cheap USB hdd casing:
1) Open the HDD casing, make sure that it supports the PATA/IDE connector !
(some even have both, like in my case I had pata/sata and usb+ethernet output).
NOTE: I Had to swap the data cable to a longer one since the stock cable was around 10cm.
2) Power up your computer and start xplorer360.
3) Do the unlocking ritual on the xbox with any method of your choice, I choose to use audio copy/play and
it worked from the first try.
4) Unplug the data cable after you are sure that the hdd should now be unlocked
(play audio for 10 seconds for example and then pause).
5) Plug it into the usb casing, power it up and windows should detect it.
6) In your computer, focus on Xplorer360 window and choose: [Drive] -> [Open] -> [Harddrive or Memcard].
Just wait a few seconds and it should detect the partitions and you are good to go!
