So in this lesson, we're going to learn how to encrypt an external drive.
Now, this can be a USB flash drive.
It can be an SSD connected to a SEITA to USPI connector really doesn't matter just any external device.
So on this external device, we've got some data on it.
And since we're going to have to wipe the disk out for this to work, we're going to have to go ahead
and back up our data.
So once our data is backed up, then we're going to want to go to disk utility.
And what we're going to do is we're going to trace our data, drive into a format that is incredible.
So you can see here I right now I'm in MSDOS and I can choose my source extended, journaled, but even
that's not incredible.
So what do we do?
All right.
Well, if we hit cancel, we go to view and then we show all devices and then I click on the disc itself,
not the partition below it.
And I click arrays.
So you can see I've got more options.
And the problem is, is that I'm using a disc with a master boot record.
And for encryption on a Mac, you need to have a good partition map.
So we're going to go ahead and choose that and then we can go ahead and choose an encrypted file system.
So and this extended or a PFS.
And so I'm going to go ahead and choose apps and it's going to want to know a password.
And any time you insert this disk into a Mac, it's going to try to mount it and it's going to prompt
you for that password.
All right, so we're going to go ahead and reset and it's going to change the filesystem in the partition
map, and when it's done, we're going to have to go ahead and put our data back on it.
All right, so now that that's done, we can quit this utility and I'm going to go ahead and put my
data back on my drive.
All right, so what we're going to want to do now is inject the drive from the system.
All right, and now what we can do is we can simulate plugging the disk back in.
OK, and so now should be reading this back into the system and we're being asked for our encryption
password.
So now I put it back in and I've got access to my data and I'm on an encrypted disk, so that's all
there is to it.
If you have sensitive data that you want encrypted on an external drive, then this is the procedure
to follow.
