@rangerGR - we don't have a DroidBOX Android KitKat firmware/Gotham XBMC for the iMX6. I'm working on it, but there is nothing official. We no longer sell the MCE edition of the iMX6 I believe (I've not checked our eBay or Amazon listings recently though), but we'll still support the devices we've sold. If I get some time when I don't need my iMX6 to have an Android firmware for a few days, I'll swap it over to the Gotham based MCE/OpenELEC one, check for any undiscovered issues, and create a post for it if all goes well.
@inspector-71 I think part of the problem has been that in the past the majority of our customers were using FAT/FAT32 partitioned devices with their iMX6 MCE. I converted my external drives back to FAT32 when I was working with some old Macs a while back, otherwise I'd have seen the issue in time. I've resized one of the partitions on my little drive to create room for an NTFS partition, so testing can be more thorough in the future.
