1. it did not rocognize it so the formatting tool did not open. 2. i have only one partition on the usb, i used the win setup for a second time to put on the xp home, it asked me, if to sync click yes, if to patch etc' click no, so i clicked no, and it put the home edition, i installed on my 3 partition, like always when i make my trials, and i also on the second run told the disk to go to partition 3, thats why i wrote that it does not seem to have to do with it.
