Is it possible to fully encrypt an ntfs usb hard drive from Ubuntu 15.10 without erasing the data on it? Will I have to have a decryption program installed if I want to run it from a windows machine?

@psusi that question still does not tell me if I would have to backup my data. – Mario Kamenjak Feb 07 '16 at 19:22

"fully encrypt... without erasing the data on it"? No. To fully encrypt it you'll have to copy all the data to an encrypted form, and then even if you had the space to leave a "plain text" copy of the unencrypted data, why? It wouldn't be encrypted, so what's the point? – Xen2050 Feb 08 '16 at 17:39

because I want to keep my data. I am not sure if I have the hard drive space to transfer it on another device while I am encrypting my hard drive. – Mario Kamenjak Feb 08 '16 at 20:00
