I understand that my 3Tb Mybook Essential exceeds a Tb limit.
Would someone point me to a 'nice, friendly, easy to understand' source that can explain this and related issues such as formatting to NTFS, GPT.
Be gentle with me. :-)

Is there some reason the drive within couldn't actually have 4 kb sectors, i.e. an Advanced Format drive? Wouldn't surprise me if that's what's contained within the 3 TB MyBook.

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.

As a matter of fact, I did have a problem with the MyBook being reported as only ~375 GB. But it wasn't with Windows itself.
The current free edition of HD Tune (version 2.55) apparently cannot handle drives of this size. It reports the MyBook 3 TB as only 375 GB, and cannot perform any benchmarks. An attempt results in an error dialog stating, "Read error! Test aborted." HD Tune Pro (non-free, trial edition) has no such issue.
I suspect the free edition of HD Tune can only handle MBR disks. The MyBook must be partitioned with GPT.
Once I get the new enclosure, I expect to have to reformat my 3 TB drive, using GPT, because it is presently (and silently) encrypted (this is one reason I'm dumping the MyBook enclosure!). So it will look like an "unformatted" disk to Windows 7.
Because I have a fairly old motherboard (2007 design), it uses BIOS instead of EFI. I suspect that I would be unable to boot from the 3 TB drive, due to its use of GPT rather than MBR. But that is fine, as the drive is only for backup, not OS use.
