[comp.sys.mac.programmer] lowlevel io on scsi

Thanks again for the help. I still have a few questions though.
1)How do i pass a set of commands to the scsi port? several command calls?
  if they are passed as a block of records how does it know which is the end?

2) The hard drive on a scsi port (first one) gets id=0?

3) How many ticks is a reasonable wait for the hard drive? the number 12ms
   seems to hang in my head as the access time of hard drives?

4) Whih would be best for lowlevel formatting write or blindwrite? is write slower?


       Thanks!
