Seagate External Drive Not Mounting

Hey Everyone,


I have a relatively new Seagate Backup Plus 2TB External Drive that I have been moving files to for the last couple of weeks. I am using a 13" MacBook Air (2017) running 10.13.3, and it has been recently updated. I was transferring files when the drive warning came up about removing the drive without properly ejecting it. I unplugged the drive and plugged it back in. The drive showed up in Finder and I tried to open it, but it caused Finder to crash. I unplugged the drive and relaunched Finder and started again.


Unfortunately the drive won't even show up in disk utility (already configured to show all devices). I have tested the drive cable with another drive and everything is fine, the other drive mounts perfectly. I tried to plug in the Seagate again and it just sits and beeps periodically. I have installed the Seagate driver that was recommended and even played with the Paragon software. Nada...


I have to ge this drive running because I was in the process of reorganizing drives and there are files on that drive that I need and haven't backed up yet. Any assistance would be appreciated.

Sounds like a corrupted volume. That's one of the dangers of pulling it out without unmounting first or if there's a freeze that requires a forced power down. Most of the time it recovers, but there's the occasional time where it doesn't.


You might try and see if it mounts in Internet Recovery. Maybe Disk Utility. Drive corruption is always rather unpredictable. It might be possible to copy over the contents to a different hard drive using Restore in Disk Utility.
