Thank you, Felix. I stand corrected -- I was going by my (obviously
faulty) memory, instead of referring to the primary sources.
The key point, though is that Windoze does not recognize the
logical partitions within a type 85 partition.
I do notice that fdisk version 2.10s does not show a type 1f using
the "l" command.
Finally, the admonition from Ecclesiastes is most appropriate,
and I'll add one of my own from the same book:
And further, by these, my son, be admonished: of making many
books there is no end; and much study is a weariness of the flesh.
Ecclesiastes 12:12 KJV
