Having never owned a hard disk on an Amiga I would like to know more about
the software that makes everything work. (I'm sure there are others with
these same burning questions !)

1) The device driver (harddisk.device).  I would guess that this must be
   provided by the supplier of the controller ?? 
   Does the Commodore driver support any NON commodore interfaces ?
   Where would I get a copy of the Commodore harddisk.device ??
   
2) Using a 3rd party disk controller -- If I get the SCSI controller from
   Pacific Peripherals, with the device driver, will I be able to see
   all the 'harddisk performance enhancements' rumored in 1.3 of the Amiga-
   dos ?? 

3) Using a 3rd party disk controller -- How would this effect running some
   other operating system (ie. Unix on a 68020 coprocessor card)? 
   My guess would be that any 3rd party controller would not be supported
   by commodore, and that for the disk to work with the new OS, I would
   have to either wait on Pacific Peripherals to write a driver for it
   or write my own.  Will this be the case, any speculation ??
   If I did end up writing my own driver, what information about the
   controller will I need ??

4) What other software modules are required for harddisk operation, and
   who provides them.  (ie... formatter, consistency checking programs,
   backup utilities, diagnostics )?

Thanks in Advance
