I wouldn't recommend this drive to anyone, as it doesn't work with VISTA!! What a waste of money to have a piece of equipment, where the mfg doesn't support you with an UPGRADE TO YOUR SOFTWARE for new operating systems. There customer support is terrible, and the only fix I can see is to pay an additional $49 to Dantz who now does their software (Retrospect Backup) who has offered an upgrade from vs. 6.5 to 7.5 for an additional $49. I just installed approximately 20+ new programs in the past 3 days on my new Vista operating system....and not one of them charged me for software updates because of Vista. BUYER BEWARE.
