I have a external USB mass storage drive. This is a replacement. I say that because on the previous drive I had set up the permissions so that only I (the owner/administrator) could access it; other users were denied access to the drive.
I seem to have forgotten how I did that because I can't get it set up again on this new drive. :(
I did this before WITHOUT any 3rd party software. I want to do it again the same way.
While I couldn't find "Computer Manager" on Vista (I know it exists on XP), I went to the drive in Windows Explorer and did what you suggested and it worked. It's all set.
Thanks.
I'll also look into trueCryp.
