I honestly wouldn't have thought about doing that since I come from the era of cracking Amiga disk protection by raw copy, and 880k meant 880k whether it was all used or not.
Back in the days when I worked with BBC Micros, copying floppy disks (assuming you could afford a floppy drive) would take ages, and much disk swapping if you didn't have two drives. Many people, including me, wrote "smart" copiers that only copied the sectors that were used. I used every free KB of memory that I could to buffer those sectors - it worked best with the 6502 second processor which gave an additional (nearly) 64KB of RAM, and was absolutely stonking with the ARM second processor unit with 4096KB of RAM.
