whois asks: "I just purchased a new Compaq laptop and noticed a feature in the BIOS called 'DriveLock'. It locks the drive so a password has to be entered on startup. If you take the drive out and put it in a system without a drivelock BIOS, the system can't boot from the drive. There is very little information on the web about this feature. Most people talk about what happens if you lose your password (buy a new drive) and what happens if you want to reuse the drive in other machines (you can't). What I want to know is the tech specs on this. Is it security through obscurity, and just sets a password in the drive BIOS, or is it doing encryption in hardware? My guess is it's the former, but I'm submitting to find out if anyone knows the real story. Here is an HP doc that mentions it in passing." According to information provided by the included links, this "feature" isn't something you can disable, either. Are we likely to see more manufacturers tie hardware together like this, in the future?
