Partitions start at sector 63 because traditionally that's the first sector
of the second cylinder. If the partition starts at a lower sector, then the
metadata of the filesystem might get split between two cylinders, causing a
performance impact due to drive head repositioning (older -- like, *really
old* drives -- have slow and inaccurate actuators; repositioning heads
takes time because after moving the heads, the location needs some fine
tuning by reading some calibration data embedded in every cylinder).
