Reset security setting and file permission on Windows 7?

Hi guys.
I am using Windows 7.
I disabeld access of a specific account (for example, 1390).
My Account (moahce) had full access to information.
After a while, I had to replace my windows.
Now the drive does not work and does not let me access the files.
The account name is even "moahce".

plz tell me : can i reset Security Setting and file permission ?
 
you need to be running as an administrator as I don't think the UAC can elevate privileges for this.

right-click on the folder containing contents to be accessed.
click on Properties. You need to see the Security Tab (next to Sharing Tab).
if it's not present, you'r not running as Admin.

click on the Security Tab of the properties and see top and bottom portions;
leave the bottom alone.
in the top portion is a list of groups and users; if your login is listed, click on it
else click Add and insert your logon-id.

Now use the lower portion and click Advanced and another window is presented.
click on your login-id and click Edit.
in the list of permissions, [x] the Full Control. and click OK

at the bottom left is a [x] box for Inherit from parent CLEAR IT
and you get COPY vs REMOVE; click REMOVE then click OK
