Help! I locked my data drive!

Iris3 · 19 Sep 2010

Hi, looks like I am in some trouble. I was trying to limit access to my hard drive (D:) on the guest account, so i logged in as admin and went to security on properties and denied full control and users. But now even my admin account can't access the data drive. it says access denied. and the security tab is not there any more when i click properties. How can i fix this problem?
ps. i have two hard drives (NTFS both) and the one i locked is not C:, but another i set aside to put data in.
Thanks in advance!

See if it works in safe mode, using this administrator account

On what permission entries did you put DENY Full Control on?

You might try running these from an Administrator command prompt:

Code:

takeoen /F [Drive]: /A
icacls [Drive]:/grant Everyone:(F)

Maybe work may not.

cloud is my computer name...
so i denied full control on Users(CloudWUsers).

takeoen /F [Drive]: /A
icacls [Drive]:/grant Everyone

F)
command promt denies them saying that it doesnt recognize it...the drive letter for the hard drive i locked is D:.

I hope someone can help you resolve this issue but as you have probably learned it is best to stay away from the 'Deny' permissions.

It is very rare that the 'Deny' permission is required, usually just not adding a user or removing a user from the security group will be enough.

This may help with understanding NTFS permissions (see the Allow vs. Deny Permissions)
NTFS Permissions Overview & Restrictions.

Hope this is sorted for you soon.

You are going have to wait for me to set up a test machine to find a solution. Cause there is no way I'm going to try messing with deny permissions on my production machine.
