ProDOS Access Unit: Volume not found error

The original release of SANE uses an early version of the ProDOS Access Unit. This version of the Access Unit checks the ProDOS disk for the version of ProDOS that formatted the disk, accepting versions of ProDOS equal to 1.0 or less. If the version on the ProDOS disk is greater than 1.0, such as 1.1.1, the Access Unit returns a 'volume not found' error.
For example, if you initialize a ProDOS disk using ProDOS V1.1.1 and then use SANE2 disk to build a custom FP library for ProDOS, the machine alternately:

1. reboots during the build
2. tries to access the disk after which the Access Unit returns a 'volume not found' error.

Workarounds

1. format the ProDOS disk from ProDOS 1.0

or

2. update to the latest version of the ProDOS Access Unit, available on SANE2 through Media Exchange.
