I hope this will likely be useful to anyone:
Admins-MacBook-Professional:~ admin$ diskutil mount /dev/disk3
Quantity on disk3 didn't mount; if it has a partitioning scheme, use "diskutil mountDisk"
If the amount is broken, strive the "readOnly" possibility
If the amount is an APFS Quantity, strive the "diskutil apfs unlockVolume" verb
Admins-MacBook-Professional:~ admin$ mount drive /dev/disk3
mount: You could specify a filesystem kind with -t.
Admins-MacBook-Professional:~ admin$ mount -t /dev/disk3
Admins-MacBook-Professional:~ admin$ mount drive -t /dev/disk3
utilization: mount [-dfruvw] [-o options] [-t external_type] particular node
mount [-adfruvw] [-t external_type]
mount [-dfruvw] particular | node
Admins-MacBook-Professional:~ admin$ mount -t drive /dev/disk3
utilization: mount [-dfruvw] [-o options] [-t external_type] particular node
mount [-adfruvw] [-t external_type]
mount [-dfruvw] particular | node
Admins-MacBook-Professional:~ admin$ diskutil verifyDisk /dev/disk3
Nonexistent, unknown, or broken partition map scheme
In case you are certain this disk comprises a (broken) APM, MBR, or GPT partition
scheme, you would possibly be capable of restore it with "diskutil repairDisk /dev/disk3"
Admins-MacBook-Professional:~ admin$ diskutil repairDisk /dev/disk3
Nonexistent, unknown, or broken partition map scheme
In case you are certain this disk comprises a (broken) APM, MBR, or GPT partition map,
you possibly can hereby attempt to restore it sufficient to be acknowledged as a map; one other
"diskutil repairDisk /dev/disk3" would possibly then be needed for additional repairs
Proceed? (y/N) y
Partition map restore full; you would possibly now need to repeat the
verifyDisk or repairDisk verbs to carry out additional checks and repairs
Admins-MacBook-Professional:~ admin$ diskutil repairDisk /dev/disk3
Repairing the partition map would possibly erase disk3s1, proceed? (y/N) y
Began partition map restore on disk3

The partition map seems to be OK
Completed partition map restore on disk3
Since I’ve tried just about each terminal line beneath the solar, I believe the important thing was the sequence wherein this labored, which was:
mount -t /dev/disk3
mount drive -t /dev/disk3
diskutil verifyDisk /dev/disk3
diskutil repairDisk /dev/disk3
diskutil repairDisk /dev/disk3
Once I heard tried to verifyDisk and repairDisk a number of days in the past it had not labored however in some way with this sequence it was in a position to restore the partition map
Thanks to all of you guys who’ve tried to assist me with this.
I’m glad to have my information again 😉
