Help, I restricted access to one of my disk drives

Open an Elevated Command Prompt
then:

Code:

takeown   /f   X:
or maybe
takeown     /f     X:\

replace X with actual drive letter of unaccessible volume
Does that work?

I assume this is what you where trying to do.

Sorry Brink.... I actually told him to do the same you told him earlier

LOL, no problem. :)

He should change
Authenticated Users = Change
Users = Read+Execute
and change the owner to System

as well. Although he just wanna have access. But this is the default for data partitions.
