My primary hard drive (OS & softs) doesn’t work (fortunatly important datas are on the second).
So i don’t have licence (the license was on the primary drive)
2 solutions:
1)The dongle is close to me, i can wait a little
or
2)The dongle is in a far away galaxy so I send a license request ?
Now XP boots on a new WD Raptor SATA 150 10 000 rpm (and it boots fast 
)
