How can I resurect my external drive in order to make it a dual boot (LION+SNOW)?
I tried many things but none was working like other external hard drive.
Now I can see the drive in the Disk Utility apps but not its first partition so when I initialise it, it return an error mesage on the formating process : unable to write on the last bloc. Whatever the format I chose : (Extended Journalized, PPC or MBR for MS-DOS).
then it dissepears from the apps. I have to power recycle it, and launch the process from the Virtual Disc and start all over.
Is there a way or have I screwed up the drive beyond repair?
Model : My Passport

Thanks for any help.
