George,

1) Do you mean a low level format to completely wipe the drive?
2) Do you mean the low level format is OK but you want to format part of the 
drive for Disk Basic or OS-9?

I have a Ken-Ton hard drive system and should have the support programs that 
came with the system. If necessary, I could e-mail you those programs.
The Format programs are mostly for use with the Adaptec interface/controller but 
there is a FORMAT-N.BAS program which seems to be for SCSI N type drives.

Of course if your low level format is fine, you won't need anything other than 
Disk Basic or the correct OS-9 drivers.
Ken-Ton systems and RGBDOS were designed mainly for 256-byte sectored drives. 
You say yours is 512-byte sectored so you may need HDBDOS software or other 
types that can handle these type of sectors.
