I changed the permission of my external hard drive so another user couldn't access the files or read/write. Now I can't even see it in the Finder on my Admin account, but it's there in disk utility. If anyone could help me change it back I'd be very appreciative. Thanks

Open a new Finder window and choose Go to Folder from the Finder's Go menu. Type or paste in /Volumes/ as the folder'a path. If you can see the drive in the Volumes folder, select it and choose Get Info from the File menu. Click on Show Original, and then choose Get Info for the original item. Under Ownership & Permissions, correct the settings for the drive and close the window.

Thanks for your reply, It showed up in /Volumes but it would not let me change the permissions. I changed owner to my account but it kept reverting back to system when I closed the window. Thanks for anything you can do.

Open the Terminal in your /Applications/Utilities/ folder and type or paste in the following:

chmod 777

followed by a space. Then drag the drive from the /Volumes/ into the Terminal window and press Enter. If this command gives you a message about not having permission, preface the command with 'sudo ', and run it again. Type in your administrator password if you are asked for it.

Thanks so much for your help. It's working perfectly now.
