After a frustrating weekend trying to get my two dynamic drives working with Vista I finally figured it out: 1. Vista only supports Dynamic drives in Business and Ultimate - not Home Premium. I upgraded from XP Pro to Home Premium. Try to find out where Microsoft tells you that Premium doesn't support dynamic drives - I couldn't. Microsoft wanted me to upgrade to Ultimate for an additional $ 169 . . . I didn't want to. 2. It turns out that unless you are really using the features of dynamic drives you can easily switch them back to basic (so Vista can see them) without data loss. The instructions are right here (forget the ad): http://thelazyadmin.com/index.php?/archive...asic-Disks.html The trick is to find diskprobe.exe. I took it out of the support cabinet on my old Windows 2000 disk. If you are running Vista you can not download it from Microsoft. Best bet is to pull it off an old windows disk. It worked perfectly and was really really simple. Be sure to 'run as administrator' when you run the software. I hope this saves everyone lots of time (and money).
