Well it took a bit of time but I am back on the road again...
I have not been very active on here for a while and when I have it was with CygWin...

Well this MBP had to go back to the Apple Store for a new disk drive.
It was repaired under warranty and I was very pleased with the service. However, returning this tub back to not quite the same as it was before has shown up a major bug with AudioScope.sh.

Arduino would not show up as a device in /dev and after scratching my head as to why I had to install FTDI device drivers for it to work. I reaaly don't remember doing so originally but I must have.

This point is now made in the Manual with a pointer to the drivers and I also decided NOT to install XCode, (gcc), just in case there are quirks that might make AudioScope.sh work when it shouldn't...

Anyhow guys I am back and lurking with a new HDD in this MBP...

Apple get the thumbs up from me and now I can get back to shell scripting...

WREN(3) 						     Library Functions Manual							   WREN(3)

NAME

       wren, ata - hard disk interface

SYNOPSIS

       bind #H[drive] /dev
       bind #w[target[.lun]] /dev

       /dev/hd0disk
       /dev/hd0partition
       /dev/sd0disk
       /dev/sd0partition
	...

DESCRIPTION

       The  hard  disk interfaces (wren, #w, is a SCSI disk; ata, #H, is an IDE or ATA disk) serve a one-level directory giving access to the hard
       disk partitions.  The parameter to attach defines the numerical SCSI target and logical unit number or the  IDE	drive  number  to  access.
       Both default to zero.

       Each  partition name is prefixed by hd and the numeric drive identifier.  The partition always exists and covers the entire disk.  The size
       of each partition as reported by stat(2) is the number of bytes in the partition, so the size of is the size of the entire disk.

       The partition also always exists; it is the last block on the disk for SCSI, second to last for IDE.  If it contains valid partition  data,
       those  partitions will be visible as well.  Every time the device is bound, the partitions are updated to reflect any changes in the parti-
       tion file.

       The format of the partition file is the string

	      plan9 partitions

       on a line, followed by partition specifications, one per line, consisting of a name and textual strings for the block start and	limit  for
       each partition on the disk.

       The program prep(8) writes the partition table for the disk; its use is preferred to writing it by hand.
