Hi Michael, Thanks for your response.
My higher level goal is to recognize partitions that TM will actively try to use on so I can avoid them. Media with TM data not related to this machine need different handling. I need to be sure I don’t interfere with TM in any way. I don’t believe using the partition name alone will be sufficient.
