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

NTFS can only be properly handled by Windows. It would be best to use a Windows machine to encrypt it.
