    Units of what? Probably jiffies. Also "unused" is actually better
    described as "idle".

    Looks like (in order):
    - total number of I/O operations on this drive
    - read I/O operations
    - read I/O sectors
    - write I/O operations
    - write I/O sectors

    This appears to be the time in seconds (i.e. unix time = seconds
    since Jan 1, 1970), when the system booted. time(0) - btime will
    give you uptime in seconds, (as should the sum of all the "cpu"
    times / HZ, if you knew what HZ was in userspace).
