[Coco] OS-9 128MB max hard drive - /sd1

[Bob Devries]

IMHO, the driver should quietly accept a service request which it could 
be expected to handle (like SS.WTRK) even though it does nothing, and 
generate an error (usually error 208 - Illegal service request) for any 
other service requests.

Error 246 is Not Ready, and would apply only in cases where the drive 
doesn't spin up etc.

I do recall doing that on my OS-9000 virtual floppy driver (RAM disk that honors all the settings of a real device so you could BACKUP to it). I made it honor a list of driver setstats and just return as if I did them, even though I did nothing. I still rejected unknown ones.
