You can TRY to format your 20MB as RLL, but if you value your data,
I wouldn't recommend it.  I seem to remember an argument about this
earlier this year.  Maybe it will work for you, but from personal 
experience, the problems aren't worth it.  If you wan't to try it,
at least get a program like spinrite to have a look at the disk
and check it for potential problems.  

Another idea if you have both MFM and RLL controllers is to install them
both. You will need to change the jumpers on one of them to change the
IO address and interrupts (I hope you have the manuals!).
