Warning: neophyte questions follow.

I recently obtained an old IBM XT with a 360K floppy drive and 10Meg Hard
drive.  I wanted to boost the storage capacity so I bought a 720K 3.5" floppy
drive and installed it.  It works fine with already-formatted disks, but when
I try to format a disk (format a: /N:9 under Dos 3.3) I get "parameters not
supported."  Question 1: Do I need a new controller?

Question2: I want to get more hard disk space as cheaply as possible; can I
replace the hard disk controller with an RLL controller?  Would this be
risky?

Thanks...
