I Have a 1TB WD My Passport that I've been using for some time. I originally never encrypted it and I've used a little under 500gb of space on it. Is there any way I could encrypt the the drive without having to backup and format it?
I was thinking I could create 2 partitions on it of 500gb each, encrypt the first partition with LVM, transfer the contents of the second partition to the first, and then encrypt the second (I originally wanted two partitions on it anyway), because I wouldn't be able to back up my information to my computer since it does not have enough room.
But I didn't know if it was the most ideal ways of going about it and I didn't want to risk losing my data if there was a better alternative.
