That is not surprising because there is no such thing as "formatted as 
ADFS". The disc format is called FileCore E+ format, and it is used by 
ADFS, SCSIFS, IDEFS, RAMFS and various other filing systems that offer 
native RISC OS format. The only difference between these filing 
systems is what kind of interface RISC OS uses to get at the sector 
data, but the format is the same. Of the above the ARMini only 
supports RAMFS (RAM disc) and SCSIFS (USB mass storage devices).
