I have run into this issue for the first time since Vista b1 all the way to 5600. After Beta 2 and Going to the next to builds including 5600 (running now) I have a hot swap drive for backup. I never acually hot swap it just turn it on at boot if I want to back up files or access information on it. After install 5600 with this drive on so Vista saw it. When I try to access any of the folders in either partition on this drive it tells m I am not the owner. I have tried to take ownership of a complete folder or drive and it fails. I have to manualy take owner ship of every file I want to open when I go to open it.. This wouldn't be so bad if I didn't have pictures/mp3's ect. on this drive so it gets very tidious. I still have taken ownership of all the files just haven't had time. I am wondering if this is going to constantly happen with a HS drive in Vista. Thanks. Chris S.
