Thanks, that was an interesting explanation. Though it does lead me to ask: what is a "set mark" and how does it differ from a "file mark"? `man st` does a much better job of explaining the difference between `fsf` and `fsfm` than the `mt` docs: MTFSF Forward space over mt_count filemarks. MTFSFM Forward space over mt_count filemarks. Reposition the tape to the BOT side of the last filemark. I’ve got a project that would work very well with linear data streaming, but it looks like even the cheapest of used tape drives probably only break even with HDDs in the tens of terabytes. Ah well, one can dream...
