Just in case you will decide to encrypt a whole HDD: Keep in mind that some BIOSes in some situations searches for MBR, and if it's not present, the drive will be regarded as "empty". Therefore BIOS could set HPA and write its backup information to it. As control block of GELI resides at the end of underlying provider (HDD in our case), it will be destroyed.help
