No, this is an entirenly different issue. Using special programs, you can
really get 2.0MB (2 * 1024 * 1024 = 2097152 bytes) on a floppy disk.
Hard disk vendors generally use 1 GB = 1,000,000 bytes. Calculating "real"
GB's from this gives you:
1,000,000 / 1024 / 1024 = 0.95367432 GB
So, drive that is sold as 10GB really is only 9.54 GB.
