My guess is that you didn't run fdisk, THEN disklabel, THEN bioctl. This stays true for any use of software, not just crypto. If you don't run fdisk prior to disklabel, a. The BIOS may not be able to boot from the device (if necessary) b. Your disklabel will be overwritten by the filesystem itself if it starts at block 0. c. You must start the first partition past block 0, block 64 is standard for various reasons. Chris
