I have a 2TB WD My Passport for Mac that I use as the Time Machine for my mid-2010 13-inch Mac Book Pro.
I also use it as a portable external hard drive to store other important files and my i Tunes library. Also, when I start up Disk Utility, it takes a long time to appear on the list on the left hand side and when it does and I attempt to use First Aid, it fails and gives the following text: Is there some way I can repair the hard drive and avoid losing all my data?
I can only assume that the problem that caused her Mac to restart also corrupted my hard drive somehow. If this does not work then contact a data recovery company.
You may try formatting the drive in order to use it again but this will delete all data stores in it.
Hello Paul, I second Hamlet's reply of file recovery from an unmounted drive.
