In another post (thread 37181), joemike noted: “…Apple does not recommend putting the Time Machine backups on a drive with any other files. Not even if you put the Time Machine data set in a separate partition.”

That caught my attention as I thought partitions were inviolate. And if they are not inviolate, can it also be that different volumes are likewise not inviolate?

And to make matters worse, is the answer dependent on whether the drive is spinning or SSD?

Clearly, I am confused. So please, any info/clarification will be appreciated.
