Excellent hard drive. Compatible with all versions of Windows including the latest Windows 7. Very easy to use. On the website it should be stated very clearly that it can be protected by a password. I said that to set up a password must first specify "never" in the backup process automatique.Car automatic backup is not really useful because it asks that this external hard drive and computer are permanently connected so that it's so easy to manually back once a month for example. Sincerely.
