The only way to do this is the Encryption has to fully complete first, only then can you decrypt the drive.
Turn off FileVault encryption on Mac - Apple Support
FileVault status can be obtained via an Applications -> Utilities -> Terminal session
fdesetup status
FileVault is On.
Encryption in progress: Percent completed = 44.48
diskutil cs list | grep 'Conversion Progress'
Conversion Progress: 44%
Conversion Progress: Optimizing 48%
FileVault disable in the middle of encrypting via an Applications -> Utilities -> Terminal session
sudo fdesetup disable
Password: <your admin password, then Return key; it will not echo, but it will be read>
I finally managed to decrypt the drives. I found an obscure reference to booting with the "R" option - then the File Vault program brought up the decrypt option. However, I could not find a way to select a drive - it only decrypts the boot drive. Dreadful - took me days screwing around - something that should have been obvious!!!

You can see Volume UUID of all volumes if you use the terminal method, copy and paste:
diskutil info -all

Were these drives encrypted with some application other than FileVault?
If so, you will need to address this issue with that application.
If not, then by virtue of turning FileVault off, the drives should automatically be decrypted by the OS without further intervention by you.
Have you been using them during these years?
These are external drives?
Right-click (or control-click) the drive image in the sidebar of a Finder window.
Do you now have an option to decrypt the drive?
Apparently, FileVault doesn't do external drives.
If drives could be decrypted without the password and app that would defeat the purpose of encryption. You should not be able to decrypt the drive without the correct password or assistance from the encryption app developer who may know of a bypass procedure.
It starts with you having a valid password, and the same software solution that encrypted the drive, so it will be compatible decrypting it with that password.
That option does not exist that I can see. I can encrypt, but NOT decrypt.

Hi Bob, yes, I tried using a terminal session but wasn't successful at it.
Apparently I'm late to the party. 😄
