disk utility – Unable to mount external Hard drive (“timed out waiting to mount”)

Spread the love


I have an external hard drive that I am trying to mount on my mac. It was working fine until I inadvertedly pluged it out before proper ejecting.


I can see the disk with diskutil

/dev/disk3 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *2.0 TB     disk3
   1:               Windows_NTFS ⁨disk_name               2.0 TB     disk3s1

I tried the following command with the (disapointing) following outputs:

$ diskutil mount /dev/disk3
Volume on disk3 timed out waiting to mount

$ diskutil verifyDisk /dev/disk3
Unable to verify this whole disk: A GUID Partition Table (GPT) partitioning scheme is required (-69773)

N.B. I have another USB drive that work fine with a Windows_NTFS partition. Moreover, the disk mounts without any problem on a windows machein (sic!), meaning I can see the content of the hard drive without problems
