Hi to you, all. I've a friend who purchased a new external hard disk. His purpose is to use it as an external hard disk for only saving there music files and other kind of data. He is a totally blind pc user with Ilm Jaws 6 and windows xp hoem edition. The question is: When he connects this external hard disk, does he need to activate his Jaws Ilm authorisation and loosing one key or not? second, when he connects this external 400 GB hard disk, does he need to connect the usb cable only or he must connect his external hard disk first to the electricity power? I didn't use this product and I told him to ask his question here. Many thanks for any help. Moti Moti Azrad Musician & Piano-Tuner motia@xxxxxxx Israel
