I have been reading a lot on getting usb drives encrypted with password on Mac OS and that it should be so easy. But no matter what I try I just do not get the option 'Mac OS Extended (Journaled, Encrypted)' to appear in Disk Utility. I am on 10.13.1 version of OS.
Can anyone help me here or tell me what I am doing wrong. I think I am more then advanced Mac user and have for years always been able to figure things out, but now I am stuck!

Reformat External Drive To Mac Os Extended Journaled Format Which Is Required
Reformatting an external hard drive for use with Mac OSX is not as difficult as it might seem. In a few simple steps you are ready to go and can save your back-up files to the external drive, keeping your information safe and giving you peace of mind. Keep in mind that a MAC can generally read other file formats, but for the best performance and to create a bootable disk, formatting exclusively for MAC is required.
Part 1: Which File Format You Should Choose?
Before you begin formatting the drive, there are a few things to do. The most important, you should decide which format to use.
There are a few file formats you can use, but it depends on the purpose you want to use the drive for. Which one is right for your circumstance? We'll describe them here, you'll know your choice after reading the details.
APFS: This is the default file system in Macs with High Sierra. It is efficient and reliable. However, it won't be readable and usable on machines that are not running Mac High Sierra, and Windows or Linux PCs. What's more, it is compatible with SSD and flash storage devices only.
Mac OS Extended (Journaled/HFS+): If you didn't update your Mac OS to High Sierra, the default file system on your Mac shoule be Mac OS Extended. Mac OS Extended (encrypted) would be an ideal option if you probably carry your laptop or external drive here and there. You can encrypt it so that no one can access the contents on your drive.
MS-DOS FAT (aka FAT32): In addition to Mac, it can also be written and read by Linux and Windows. It enables you to regularly share files with your friends who own a PC. Nevertheless, this older file system is limited to no more than 4GB and there might be security issue and disk errors.
ExFAT: It is similar to ExFAT which can be read by both Windows and Mac, but it can store more than 4GB files.
NTFS: As the default file system in Windows, it can only read by Mac OS, writing to it is not available. Luckily, there are third-party tools to help you do so.

Just updated to macOS Catalina 10.15.4, and immediately one of my two external Time Machine drives, both of which are 100% (verified neither are experiencing any mechanical problems), stopped being recognized by my Mac, and when I tried to reformat it using Disk Utility, using HFS+ Encrypted (Mac OS Extended (Journaled, Encrypted)) option,
I've tried attaching 2 other known good drives, all exact same results. It appears Apple broke something with the .4 update, as this was not an issue, ever, in any previous version of macOS for me.
Oddly, I can use APFS encrypted, but not HFS+ Encrypted.
