Windows – External HDD not assigned drive letter on Windows

external hard drivefilesystemshard drivewindows 10

I have an external 5TB drive (Seagate Expansion Desk). It has 2 partitions (FAT32 & NTFS) with valuable files. I may have unplugged it before without doing it "safely" on Windows 10. It is now not recognised as a hard drive by Windows Explorer or diskpart.exe although seen in disk management, device manager and "devices and printers".
The option to "Change Drive letter and paths" is disabled in Disk Management, quick tests with SeatTools for Windows reveal no issues. Running out of ideas, please help.
So far I have tried:

updating drivers
uninstalling drive
running quick tests with SeaTools for Windows

Disk 1, the external HDD, has no recognized file system shown in Windows Disk Management.

If you do not need the data on the disk, format at least one partition NTFS. Of course, it may no longer be Mac compatible.
Install Apple HFS drivers for Windows for read-only access. [Actually, I would not recommend writing to this HDD at all from Windows if it has essential backup data!]
Install Catacombae HFS Explorer. Again, this is for read-only usage.
Dual-boot or run Linux (e.g. Ubuntu 16.04 LTS) from a Live CD. You may need to install hfsprogs and mount the drive:

sudo apt-get install hfsprogs

sudo mount -t hfsplus -o force,rw /dev/sdXY /media/mntpoint

Though this gives write access, do not write to the HDD if it has valued data.
