    By saying that he has FIVE disks that are entirely encrypted, he gave you a clue that they were not all bootable disks. Why would one worry about putting an MBR on a non-bootable disk? If there's no MBR on the disk, why would one worry about whether it is encrypted or not?

    Why is everyone so hung up on encrypting a boot record, anyway? The purpose of encrypting these disks is that one cannot take a disk away and gain access to the data. If someone had physical access to a system, where they could alter the system then put it back in place for the owner unsuspecting owner to use again, the encryption system used is not the problem. Given that level of intrusion, passwords and even biometric measures are likely to fail to protect the data. I'm not sure a secure token would be enough for that dedicated a hacker.

    For less drastic protection, allowing the boot disk to load up the encryption algorithm and present a challenge and password should be sufficient. It would be very easy to configure a USB key to be the boot device for a system, and have the boot sequence mount the kernal from an encrypted disk. No MBR on the root disk at all, so the entire disk could be encrypted.

    You asked "Why is this a problem?" I did not pose it as a problem, merely shared my experience for information. If you think what I do is irrelevent, ignore it. I read opinions and ancedotes related by others all the time, and sometimes even find many of them interesting.

    On your other points, yes, it is possible that an admin could disguise a key-logger on my company laptop to steal my truecrypt password, and therefore gain access to that data. It is a violation of our corporate security policy, but it could be done. I don't expect them to go to that length to spy on me, however.

    I keep a TC volume on my corp laptop because I occasionally want to access non-corporate, privately owned files without having to carry a second laptop with me. My company allows "limited private use" of corp computer equipment, email, and Internet access, so there should be no hand-slapping involved. I want to keep my private files private, because they are no one else's business but mine.

    In the event that I have a malfunction on the computer, or I get to upgrade, or I decide to leave the company, or any of a dozen reasons that I lose physical control of the laptop, the TC volume will ensure that my files stay private. I'm not being paranoid, nor is there anything shocking or illegal in the private space that I would have to worry about, but it's still a better policy to keep the files locked away.

    There are things in the TC volume that I find funny, or interesting, that my fellow employees may not. Off-color jokes, or cartoons, downloaded discussions of non-work-related political causes, my tax information or IRA contributions, etc. It's just best to have these things kept private, even from my fellow employees. The PointSec encryption on the laptop as a whole does this for the majority of situations, the TC volume takes care of the rest.

    If someone were to truly dedicate themselves to finding out my every last secret, I'm sure they could do it. They could install a key-logger on my system, a camera in the ceiling tiles above my desk, put bugs in the furnishings around me, use TEMPEST techniques to capture the output of my monitor, etc. If they want to know that badly, all they would have to do is ask (they might have to say please, and give me a decent reason they want to know.) I'm not THAT secretive, and what I am hiding is not that important.

    Still, it's fun to use an encryption system to lock away my "naughty secrets." When it comes time to turn in the laptop, all I have to do is to erase the private.tc file from my home directory, and know that the data is gone. Even an unerase utility will not retrieve the files. It's possible that fragments of the files were swapped out to disk by the Windows swap utility, but like I said, there's nothing there THAT damaging that I'm worried about it.

    The term that is used on the Truecrypt website is "System Encryption" and it works by loading an encryption program into the boot block of the boot disk. The MBR will call the boot block, which then prompts for a password. The password is used to attempt to decrypt the rest of the boot partition. If it fails, there is no boot, and the only data that is unencrypted on the disk is the boot program itself. The rest of the disk looks like random data. If that's not "whole disk" encryption because the MBR is not itself encrypted, then what is the advantage of encrypting the MBR?

    Also, while support from external authentication devices would be nice, there is support for keyfiles as well as passwords, so technically this is a two-factor authentication system. Since the system will not boot at all with System Encryption enabled without the password entered, Automatic update for user password changes (for when a NEW USER is given access to the system) is meaningless. When the user changes the encryption password on the system, it's changed. No automatic update needed.

    It's funny that we keep hearing about "consensus." When other scientists make a discovery or a breakthrough, they gather their data, and get it peer reviewed for accuracy. If the peers cannot find fault with the process, the scientific conclusion is accepted as a working theory (scientific theory, which means that it's pretty much a proven fact, not public opinion theory, which means it's open to debate.)

    With this debate, no one seems to have enough data to form a scientific conclusion, so everyone is talking about the scientists coming to a consensus. This means that, while they do not have enough evidence to solidly prove anything, they all believe they have the correct answer, given the data that they have reviewed. Not a slam dunk, by any means.

    The evidence shows we are experiencing a warming trend. Thirty years ago, we were in a cooling trend. We know that man is producing a large amount of CO2. We know that CO2 is a greenhouse gas. We know that the sun is in a warm cycle (1600 year trend.) We know that temperatures are at 100 year highs (that's all we know, since we only started recording the temperature a little over 100 years ago.) Previous records were set in the 1930s.

    Odds are we will experience some serious draughts, and see some sea level rise. It might even cause some massive problems for people who already live in horrible places (Sahara Desert, anyone?) Increased CO2 means increased crop production, which means more food, if we can get water to the crops. Some low lying cites might be at risk for periodic flooding. If we have a massive die-off, we will produce less CO2, in which case the humans can no longer be blamed for the increase in temperature. Either way, the effects will not be catastrophic in my lifetime.

    Thank you Walt-sjc. That was a much better reply than I was going to offer. For El-Lobo, understand that I have been working in computers since 1985. I began my career in the IT industry by installing a Novell network for the company I worked for, and writing an integrated inventory module into the corporate accounting package the company used. Before I did that (and after, for a couple of years) I repaired microfilm cameras and film processors, so I was a hands-on technician.

    Since that time, I've installed, configured, maintained and repaired such a huge number of computers I would not be able to give you a decent count. Yes, there is no magic, I agree with that statement. There are, however, problems with every operating system out there. I've worked on Apple OS, VMS, Wang, Novell, MS-DOS, DR-DOS, OS-9, Windows 1.0, 2.0, 3.0, 3.1, 95, 98, ME, XP, 2000, and 2003, Xenix, Unix (system V), Solarix, AIX, HP-UX, Linux, and BSD. I believe I know a thing or two about operator privilege and permissions. I also know what clear text configuration files look like.

    The Windows registry is fine as a machine readable configuration database. It's quick to access and fairly accurate. If you know what you're doing, it can be easy to manipulate with simple tools (regedit.exe.) It is NOT user or admin friendly, however. The fact that some companies seem to be able to write registery entries that are meaningful and user readable is fine for them, but as a whole, the registery encourages cryptic entries. This fits in very well with the purposes of malware and spyware companies, who want thier entries hard to find and read.

    The idea that I can run all of my programs (on windows) in limited user mode and avoid trouble alltogether is also bullshit. Quite a few of the programs that are normally run require so many privileges elevated that it is by far easier to just run in Admin mode. My work computer, which I don't administer, is not set up with me running as Administrator. In fact, the Administrator account is disabled, and admistration rights belong to the PC administrator in my office. He's the only one who has unfettered access to the system.

    There are, however, several small spyware or malware apps that have managed to become installed on the system. I find them and kill them, but I know that next time I look, there will likely be something hidden in there somewhere. Is this magic? No. This is BAD PROGRAMMING.

    Understand that I'm not saying that Linux or Unix is perfect. I know that there are exploits for those systems that come from programming mistakes as well. There have been several highly publicised vulnerablilities in the last couple of years for both Linux systems and BSD Unix systems (including Apple OS X.) Well, publicly announced exploits or not, everyone I know who runs Windows spends time, money and system resources on tools to keep the malware at bay. It's a running battle, and three to four times a year, there's another widespread outbreak where everyone is urged to download a fix or protection because an exploit is sweeping the nation, compromising tens of thousands of machines.

    Can you tell me when the last outbreak of rabid spyware bots was on Linux systems? When did something sweep the nation on BSD, infecting everthing it touched until Symantec could get a fix in place? I thought so.

    For all of those people who are proudly Linux free, or BSD free, and proclaim Microsoft Windows to be the One True Solution, thanks for the entertainment. For the of us, there are some who have tried all of them, and decided on one or two favorites. For my money, Linux is the best out there today. Ubuntu is the flavor of the month, and seems to be the best for me. I will say happily that I have not had time to try all the flavors of Linux, and I will probably have a different favorite flavor in the next six months or so. Although, I'm on my way out to buy a new Apple, we'll see if it can take the crown.

    For all of you who read all this, sorry for the long rant.
