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).
