I'm encrypting in-place a 1.5 TB partition on a non-system drive with TrueCrypt.
The problem is that the data became inaccessible the moment I started it, and that I can't revert the process nor access the data until it is complete.
The big problem is that it taking 36 hours and I don't understand why. My CPU has AES encryption ops built-in and can encrypt over 3 GB per second. The hard drive is a normal HD, but it takes nowhere near 36 hours to write 1.5 TB of data.
I believe it is going slow on purpose to avoid slowing down the computer. But since I can't use that hard drive anyway, and the bottleneck will surely be the hard drive write speed rather than the CPU, I want it to go as fast as possible.
How can I do that?
