The sizes are those usable on a 16-bit filing system, such as on RISC OS or DOS/Windows. The sizes are often in 'big' megabytes instead of 'real' megabytes. The '8-bit Drive Size' data is the drive geometry found by attempting to use the IDE_Identify command. The size is that seen by 8-bit filing systems, such as ADFS on the BBC/Master. A reported cylinder size of &3FFF is a special value that indicates that the drive is larger than can be expressed as Cylinders, Heads, Sectors.
