yes. two offsets, 128 sectors * 0.5k/sector = 64k. Now, I probably appreciate the value of 64k more than most people -- my first computer had 256 bytes of RAM (and that takes a while to load via a hex keypad, I must say. Even more if, as is usually the case, accuracy counts!), the first floppies I used were 90k (on a machine which had been "maxed out" to 64k RAM). Wasting 64k is not something appreciate. But let's also be realistic here... You are also talking about TWO file system blocks for biggish file systems, ONE file system block for a too-biggish file system. You are talking about 16 4k file system fragments, or 8 8k file system fragments. You are wasting lots of time trying to save a tiny tiny tiny amount of space. Times a few layers, times a few disks, you are still talking about a trivial amount of storage in the 2000's. And we are now in the 2010s... If you really care, go look at the source code, keep in mind the MBR vs. disklabel partitioning, multiple platforms, and all kinds of other issues...but never forget what you hope to gain. Nick.
