Exceeding 2Tb limit questions

Makes sense.  I was aware of 512e.  I believe it’s one of the tricks that was invented to make Advanced Format drives play nicely with Windows XP.

I am planning to remove the 3 TB drive from mine and dump the MyBook enclosure for various reasons.  I suppose that means the drive will not work with Windows XP as-is.  But that’s OK.  I don’t plan to use it with Windows XP at all.  The only OS’s I really use any more are Windows 7 and Ubuntu, both of which support Advanced Format drives natively.
