Just bought an SSD and want to use WDE. Everything I've read says that the disk should be encrypted BEFORE the OS is installed because Truecrypt cannot guarantee all the data already written to the drive will be encrypted. See this post for details: https://www.wilderssecurity.com/showthread.php?t=299329 Two questions: 1) When I use WDE, I thought the entire drive was essentially encapsulated and not accessible without the password to boot. How is possible then that data will remain unencrypted (as indicated in the post above)? 2) Most importantly, what is the solution for using WDE on an SSD? I want to use this SSD but do not want to sacrifice WDE. Thanks.
