This is a 3 TB external Seagate hard drive formatted in Mac's Disk Utility as a single non bootable exFAT partition. It got unplugged from the computer and now the computer is unable to read it.

Is it possible to recover the hard drive?
Update: I had to unplug and plug the external hard drive back in. It takes about 5 mins for computer to recognize the hard drive. The following screen pops up.
I ran the first aid from the disk utility app and the operation was successful but it still show the disk as uninitialized.
diskutil list
:
/dev/disk4 (external, physical):
#: TYPE NAME SIZE IDENTIFIER

2: Microsoft Basic Data SEA_EXFAT 3.0 TB disk4s2
The hard drive doesn't show up in finder.

I think the drive is already unmounted, if not then unmount it and do this
try mounting in read only mode by doing this
Check if the drive is hijacked by the system
If you see your disk there hijacked then use this to kill this process
You should immediately see your drive at the finder's sidebar.
