Hi all, I wanted to prevent the guest users on my laptop from accessing D: drive. So from my admin account, I set the permissions on my D: drive to deny all for the Users group, without even looking at all the permissions listed. I thought these permissions would affect only the non-admin group....but I went wrong and now cant access any file in D: even from the admin account. Have some serious work in that drive, and need some urgent help in getting back my data...any help would be appreciated ! Thanks !
