The simplest rule of thumb is to start a partition at 1MB, and specify all partition sizes in whole MB's. It solves this, and maybe also for SSDs. The open question is some SSDs have 2+MB erase block sizes and it's not clear if there's a benefit, or even a way, to partition on 2MB boundaries. Any recent partition tool starts the first partition on a 1MB boundary. Chris Murphy
