But while Permissions Reset can fix a file or folder of items, it's not a great choice for something as large as a home folder, which contains many different files with different types of permissions. A better choice, if a bit more cumbersome, is Password Reset, another utility that is built into your Mac. In addition to resetting a forgotten password, you can also use Password Reset to repair file permissions on a user's home folder without actually resetting the password.

These folders are then shown as the specific hard drive in the Finder sidebar, or on the desktop, but technically you could go to the hard drive's mount point which appears as a folder , get info on it, and adjust access permissions there. When entered, the system will open a Finder window that shows you the hidden Volumes directory and the hard-drive mount points within it.
Note that within this directory the boot drive is shown as an alias, but secondary drives attached to the system are shown as folders with a relevant hard-drive icon such as generic internal or external, or Time Machine. Accessing these drives and getting information on them can also be done from the This Computer section of the Finder the "top level" of the Finder's organization or from the desktop. Ultimately it is not the drive itself that you are allowing or denying access to, but rather it is this mount point in the filesystem tree that you will be allowing or denying specific users access to whenever you set permissions on a specific drive.
While you can change the owner of the drive the top user in the permissions list , if this is set to "system" then you do not need to alter it since that will not affect any users on the computer. To limit drive access to specific people, set the "Everyone" permissions on it to "No access" and do the same for the group right above "Everyone"; it should be either "admin" or "wheel". Optionally, you can remove the group entry on the drive.
The next step is to click the plus button, add a user account, and then give that account either access or no access to the drive. To simplify things, you can also create groups of users in the Accounts system preferences and then add them to the drive's permissions list to either allow or deny them access.

Keep in mind, however, that this approach introduces the security risk that all local users will have full access to the contents of external volumes.
