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.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.
