Some VXA-320 tape drives respond to a different command length than other VXA-320 drives. Unfortunately, Retrospect cannot resolve this difference without user intervention. If your VXA-320 drive exhibits communication problems with Retrospect, such as “incorrect scsiServiceResponse” messages displaying in the Mac OS X system log (viewable with the Console application in /Applications/Utilities/), then you will need to edit the retro.ini settings file to correct the problem
To edit the retro.ini file, take these steps:
In the Retrospect System Preferences pane, stop the Retrospect Engine.
Locate the retro.ini file at
Open the retro.ini file with a text editor, such as TextEdit.
Add the following lines to the end of the existing text:
Save the edited retro.ini file.
Start the Retrospect Engine in System Preferences pane.
