The first thing to try is restarting both the computer and the external device. If the data is still cor-
rupted, try running built-in operating system utilities (such as macOS’s Disk Utility First Aid) on the
drive volume. For best results, boot your computer with a macOS Installation CD and launch Disk
Utility from the CD. When you reach the macOS installation program you can run Disk Utility from
one of the menus at the top of the screen. From Disk Utility, you can run “Verify Disk” and “Repair
Disk” to find and fix any errors that may be present in your macOS installation.
If an operating system utility doesn’t help, you may need Data Rescue. This is a great solution for
recovering lost data from a hard drive which has suffered data loss or corruption. If there is a true
hardware failure of your hard drive that prevents it from communicating with your computer, there is
no software solution in existence that can fix this problem. However, since we cannot tell you with
any certainty whether or not you are experiencing hardware failure in your particular hard drive, we
would encourage you to download a free demo version of the drive recovery software of your choice.
Free software may limit how much data you can recover, but they will tell you if they even see any
files.
