Permissions in disarray after clean install
My security permissions appear to be screwed up after re-installing Windows XP Home. In connection with the clean install, I deleted two user accounts for which I manually copied their files to a second hard drive. Now I notice that the owner for many files is "Unknown" or has what I believe is an SID.
How do I best clean this up?
1) (a) Is it best to set the owner to "Administrators Group" at a high level on the drive and ensure I select "Replace owner on subcontainers and object" to let the change trickle down?
(b) Is this better than assigning the actual original owner which might be a limited user?
(c) Is it safe to remove all the Unknown users (i.e. SID) showing in the security permissions?
2) For allowing users access to the second hard drive (D: drive) where I have "My Documents", is it better to provide full control to "Authenticated Users" instead of "Users" Group? Or is there a group that is even more secure? Of course, for each users' "My Documents" folder I will provide access only to each individual user.
3) I notice my external hard drive has the root and the complete drive with full control to "Everybody". Is this insecure or must it be this way on an external drive since it can be hooked up to any computer?
Thanks for any help.

Unfortunately I don't have an answer but in having the same problem with my windows vista and have posted several times questioning permissions. After doing this system restore I found out that several files and folders and conflict in permissions. Some had the everybody some contained the administrator sign a name along with the administrator group and the trusted installer. So I truly hope somebody has an answer for your question 'cause it will also answer a few of mine

You need to take ownership of the files whose original owner was deleted...
With XP, click Start>Help&Support
Type "ownership" without the quotes into the search box at top left of the screen. That will bring up instructions on taking ownership. Since you deleted the original owner(s), you have to log in as Administrator and take ownership of those files/folders, but you won't be able to give ownership to any other user account.
Would have been better if you kept the original owner(s) accounts and used them to give ownership permission to other users, and then you could have deleted the unneeded old owner.
I dunno about Vista, but it's probably a similar procedure.
