I like to start my first partition at 1048576, which is 1Mb into the disk, and end it at 104857599, which makes it 99Mb long. After that, I use a single partition spanning the rest of the disk, starting at 104857600 (100Mb), and ending at a multiple of (1024*1024=1048576). I use LMV or RAID+LVM on top of that. Don't forget that the end point for each partition will be one byte before a Mb marker, so my first partition, ending at 104857599, is 1b before the 99Mb mark. The size of the partition includes this end byte, so the partition is a full 99Mb's worth of bytes. I hope this helps, Paul
