Wow, you guys are quiet today. To answer one of my own questions: So take the advertized size: 4000000000000
Divide it in to 1M chunks: 4000000000000/1048576=3814697.265625M Round down: 3814697M Subtract 2 for the reserved sectors at the front and back: 3814695M This equals 3814695*2048 512byte logical sectors or 3814695*256 4096byte physical sectors I would expect any drive with the same advertised size to be able to create partitions totaling up to that value. I surveyed eight GPT drives. * All are at least somewhat bigger than the advertised (decimal) size. * GPT normally does 1M (512*2048) partition alignment * GPT seems to reserve 34 logical 512 byte sectors at the beginning and end of the disk (under 1M). -- Anthony Carrico
