Please help! I cannot lose the data on the hard drive! I can only assume that the problem that caused her Mac to restart also corrupted my hard drive somehow. While it was doing this, her Mac “Restarted because of problem” and since then the my hard drive that was connected has the problems above. It was preparing the backup for some time because it had been a while since it had been backed up. It is also used as the Time Machine for my girlfriend’s 2011 15-inch MacBook Pro and the problem started when I tried to do a Time Machine backup on her computer this morning. I have had the hard drive for a couple of years and it has always worked perfectly.

Is there some way I can repair the hard drive and avoid losing all my data? Updating boot support partitions for the volume as required. The volume could not be verified completely. 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: I also use it as a portable external hard drive to store other important files and my iTunes library. I have a 2TB WD My Passport for Mac that I use as the Time Machine for my mid-2010 13-inch MacBook Pro.

Volume could not be unmounted
