My original blanket admonishment and liberal use of "some" was intentionally and deliberately more cautious. You changed things a bit to only refer to external drives and removed a "some" or two, but the problem of proper identification is tricky. You can decide how to word it, but it needs to be clear that
(a) the outer packaging is not enough with boxed internal drives, you have to actually look at the drive label to be sure,
(b) with external drives, you have to crack the enclosure open to be absolutely sure.
Notice how @memory above, had to stop and ask a question about what "some" meant? That's exactly what I want newbies to do, stop and think before cross-flashing, so they don't destroy their drives.
