Hi, I've tried the daily build of "Alternate Install" from 12 March on a 4K drive (WD10-EARS) and although the partitions now align on good 4K boundaries, I think the algorithm for creating partitions is working in cylinder units rather than sectors. So using the default install I get partition 1 starting at cylinder 2048 which as LBA 32901120 is a 4KB boundary but it is 16.8GB in to the disk. I think we should be looking at LBA 2048 as the start of the partition, not cylinder.
