Cisco UCS c240 Can't have a partition outside the disk

Hi,

I'm trying to install ESXi 5.5 on a c240 M3 UCS Cisco.

The local drive is a FlexFlash Raid 1 of 2 sd cards.

At the time of install, esx sees the local 30g card.

asks language, root password and when I click on install, it gives an error. (see attached files)

this program has encountered an error: parted util,  Can't have a partition outside the disk

I have 2 exactly configured servers, out of the box, same error... any idea?
