The main takeaway here is to back up your Mac with Time Machine or another app, and create a second or third copy of those backups if you can. Although you could try a third-party Mac data recovery software, chances are they won’t get all your lost data back. Without a proper backup, it’s really hard to restore data. I can’t emphasize enough the importance of data backup these days.

Backblaze and Carbonite are also popular options in the market, though I am yet to give them a try. One good option is to use cloud storage services like iDrive which I’ve been using and I really like the app because it’s super easy to use, and it also allows me to download Facebook photos automatically. It’s best to make a copy of the data on your external drive - as they say, a “backup of your backups”! Like any other hardware device, an external hard drive will fail sooner or later. Then, you can safely unplug the device and put it in a safe place. Instead, go back to the main desktop, locate the volume that your external hard drive represents, right-click and select Eject. When the backup procedure is completed, don’t rush to disconnect your device as this could cause potential disk problems.

After about an hour and a half, it says only 15 minutes remaining Step 5: Eject your external drive and unplug it.
