Apparently Truecrypt full-disk encryption doesn't work on Windows 8.1. Is there any free software that allows full-disk encryption on Windows 8.1? I tried Diskcryptor, and apparently it doesn't work on windows 8.1. What encryption software allows hard drive encryption on windows 8.1? Your help is greatly appreciated.
Worth a look: https://prism-break.org/en/projects/encfs/ The other one listed on Prismbreak for Windows is Diskcryptor, but you've tried that obviously.
Try VeraCrypt, a fork from TC which supposedly solves TC issues but is not compatible with it. Or R-Crypto, from www.r-tt.com, free for personal use.

Diskcryptor works well. Doesn't support hidden disk/partition but the problem is that there hasn't been any audit on it.
