    When I got my MacMini back in 2012 I replaced its HDD with an Intel SSD , then I put its 500GB HDD into an external adaptor to use it as an external hard drive and started using it for my backups ...

    in last month suddenly it gave me an error that your HDD can not be repaired ...

    so I opened Disk utility and tried to Repair / Verify / Erase or even change the partitions ... but unfortunately none of them worked.

    The error which disk utility is giving me is " This disk can not be unmounted "

    Would you please tell me how can I solve this problem ? I really need this drive to take my backups ...

    Thank you

    Try booting to the Recovery partition and see if you can use Disk Utility on the drive volume.
