What does this mean? You've encountered a well-known bug in the installer. I've experienced it too and so have many others. During the install, when you're in the fdisk partition editor, just hitting "g" is usually all you have to do to correct the bug. If you've already installed, I'm not sure what you can do to correct the bug other than go back and reinstall, this time hitting "g". There might be another way to change disk geometry without doing that, but I don't know how (anybody reading this know?). You might want to take a look at the following article, the geometry bug is discussed about 1/3 down from the top: http://distrowatch.com/dwres.php?resource=review-freebsd regards, Robert
