Hello, Installed a new hard drive in iMac with OS X Mavericks. Problem is when I plug the old hard drive in using a USB device I have the OS can see the data and access all folders except the user folder that contains the data. Attempting to open it just opens an empty window and Get Info shows the folder is empty. I can't change anything in sharing and permissions. When I plug the drive is it says It can't be repaired and will be read only. I'm at a loss for how to go about successfully retrieving the data. Any advice is greatly appreciated. Thanks!
