Gets me this Jon: Command (m for help): p Disk /dev/sda: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00026faa Device Boot Start End Blocks Id System /dev/sda1 * 1 64 514048+ 83 Linux Partition 1 does not start on physical sector boundary. /dev/sda2 65 242564 1947881250 83 Linux /dev/sda3 242565 243201 5116702+ 82 Linux swap / Solaris Partition 3 does not start on physical sector boundary. Confuzin ain't it? But it would appear to be compatible to a 512 byte scheme except for the 4096 bytes minimal write. But since its installed now, would I be safe in using gparted to move /boot and swap so they do begin on a physical sector boundary, and how can I calculate that? GParted should have warned me.
