Well, yes and no :-( The partition table of the original table has crashed, so
I've created the ISO image of the disk and now playing with it ... but, the
original drive is still untouched. So, I should play with hard drive directly
instead using the dd copy? To partition table recovery in the ISO image I've
used the testdisk utility.

Any suggestions?

Thanks a lot.
