We encounter some issue with Dynamic disk..
1) 1 Machine with 1 disk and whole disk is "Dynamic" with 2 partition C: and D:. It's turn out that MEE did encypt C: partition (even it's dynamic) but did not encrypt D: partition
2) 1 machine with 2 disk 1-Basic with C: partition and 2nd disk Dynamic with D: & E: partition. Turn out C: partition encrypt and D & E not.
McAfee KB KB74757 said it's does not work on "Dynamic" Disk however it's manage to encrypt C: partition on Dynamic disk?
I;m curios if it's can encrypt C: why it's not encrypt the D: partition as well?
dynamic disks span volumes, but the EEPC kernel only knows how to look up sector ranges for standard disks, so when it asks for the range of C:, it will only get the sector locations for the first partition.
That's why as per the release notes, dynamic disks are not supported (and they don't work either).
