Q: Seagate Backup Plus Portable Hard drive won't mount onto the Mac after OS X El Capitan Update?

Hi there,

 

So after I updated to the new OS X El Capitan, my Seagate Backup Plus hard drive won't show up in the finder. I have checked the disk utility and it shows up there, but it won't let me mount. Does anyone have a solution to this? Or do I have to wait till the next OS update till I can get it to work?

 

Cheers,

 

Chanel

Hey not sure if this will work for you but I had a problem with read and write permissions on my seagate hdd after the El Capitan Update.

I just had to re-install the NTFS driver to get my hdd working again.

You can download it from here.. http://www.seagate.com/au/en/support/downloads/item/ntfs-driver-for-mac-os-maste r-dl/

Hope this helps.

    Hi Eric,

     

    Thanks for trying to help, so I tried using the terminal to mount it but all I got was :

     

    Volume on disk4 failed to mount; if it has a partitioning scheme, use "diskutil mountDisk"

    If the volume is damaged, try the "readOnly" option

     

    and I can't even read only.

    As you can see, it won't let me mount or partition either?

    halls-10-40-253-194:~ Chanel$ diskutil mount force /dev/disk2

    Usage:   diskutil mount [readOnly] [-mountPoint Path] DiskIdentifier|DeviceNode

    Mount will mount the volume in the "standard" place (/Volumes), unless

    an optional mount point is specified.

    halls-10-40-253-194:~ Chanel$ diskutil verifyDisk /dev/disk2

    Unable to verify this whole disk: A GUID Partition Table (GPT) partitioning scheme is required (-69773)

    halls-10-40-253-194:~ Chanel$ diskutil mountDisk /dev/disk2

     

    One or more volume(s) failed to mount

    halls-10-40-253-194:~ Chanel$

    halls-10-40-253-194:~ Chanel$

    As you can see above I have tried several ways. Any other ideas, or do you suggest I try and revert back to Yosemite?

     

    Thanks!

    Thank you so much! I was talking to apple support for hours and they couldn't come up with anything as simple as this!

    Thanks so much for posting this.  After the OS X El Capitan Update I wasn't able to write to my hard drive and it was driving me insane until I found your suggestion, which immediately worked.  Thanks!
