I have used TrueCrypt for a long time…but only with TrueCrypt container files that stand alone and are mounted.
Then I branched out and started using full-volume encryption to protect some back-up external USB drive devices.
Recently, I bit the bullet and started using TrueCrypt system-wide encryption to protect my personal home laptop…all system volumes. No worries so far.
Because of that I pay close attention to TrueCrypt news, and here is some linkage, in case you are interested.

Windows 8.1 upgrade: be careful with TrueCrypt - GTranslated - Borns IT and Windows Blog - Basically, if you are using full-system partition encryption with TrueCrypt, the recommendation is to first fully-decrypt and remove TrueCrypt encryption…then apply the Win 8.1 upgrade…then reapply the TrueCrypt full system partition encryption. If not you might hose your system during the upgrade. That’s a bad thing.
