I have no idea how this has happened. I am running a VM on a drive and out of nowhere all permissions on that drive seem to have somehow become corrupt.

I cannot open directories on the drive. Everything results in Access Denied.

I have tried running icacls and takeown. Both result in access denied. Any suggestions, I have used Windows for years and have never seen anything like this.

I appreciate your help in advance.


I disabled UAC and can now access the drive - ODD. What would UAC have to do with this?

UAC has everything to do with it. Bypassing it removes all sanity checking on the ACLs, so you are free to mess with it as you like. – user3463 Sep 9 '12 at 16:45
