- You specify disk geometry in terms of 1024 byte units, but that causes no loss
- of capacity for the drive. I suspect your 7% loss came from file system
- overhead, primarily inodes, which can be adjusted if desired. You also need
- to realize that disk vendors specify decimal megabytes, whereas utilities
- like bdf use units of 1024 in reporting capacities.
