The parameter “--alternate” is not recognized by HDM 14 10.1.214.471, at execution time a message box is displayed: “Disk Utility: Can't open file –alternate" It is still like 'rothers' posted December 18th, 2013: “I've also noticed two other undocumented switches: --alternative & --multiple, can't find any reference to them in the script manual or scripts.exe -h.” User 'DrumMemory' wrote August 10th, 2010: “we still don't have any documentation for "--alternate".” My complimentary support period has expired; I assume it is wasted effort to contact support? Edit: The scripts with parameter -- alternate are created with Retention Wizard v18.104.22.168. Scripts created with HDM 14 10.1.214.471 do not include this argument. If you go into Task Scheduler and remove the argument, the script runs …. in a proper way??
