Must remember to tell that to the 6.8GB drive I bought in 1998 :-)

RO3.6 and later supports large drives (up to 128GB), but gets horribly
inefficient over a few GB.

For the A4 (on RO3.1), format the HD to 499MB for maximum efficiency - it
makes the minimum file unit half the size.  There were some third-party
filing systems that could be fitted and allowed multiple partitions - I
think Clares' BDFS was the one that would work on RO3.1

For the gory details, see:
