'Decrypting Backup Disk...' taking a long time

How long does it take to decrypt a backup disk for Time Machine backups? I need to use my external hard drive for something else soon but Time Machine just says 'Decrypting Backup Disk...' and I cannot pause it. How long do you think it should take to decrypt a 2TB external hard drive that only used up a small portion of it's space?

I accidentally unplugged the drive, so I plugged it again and the same 'decrypting...' message came. My solution was to remove the drive from time machine then re-add it. But I still don't know why it would take so long. I read another post that said the decryption process would remove the encryption above, but after removing the drive from Time Machine, all was well again...
