- MacOS through Shapeshifter.
- Shapeshifter has to buffer such 512/2048byte transfers and then copy
- the 512bytes to the Shapeshifter buffer to be scsidirect compatibel.

- Because these may read data until the datain phase changes.

- I told you what it is...it┤s up to you to read the RKM scsidirekt
- specs to check it or believe me.

- I told you in detail what the problem is...if other controllers don┤t
- signal error conditions it┤s their design choice. I┤ve decided to
- notify users about error conditions so that they know at once if
- something goes wrong with something important like the scsi bus.

- I won`t supply a bugfix because it┤s no bug on my side.
- It┤s that simple.
