Windows 10 MBR2GPT

Windows 10 keeps giving me pleasant surprises, e.g. this post.

The Windows 10 Version 1703 (Creators Update) has another feature that would have saved me DAYS.

Back in early 2015 I needed to migrate my Drobo from a MBR (Master Boot Record) volume to a GPT (GUID Partition Table) volume to allow me to expand the Drobo beyond 2TB,

I got this done by configuring a second Drobo to GPT and copying all the data from the MBR volume to the GPT volume. That took a couple of DAYS.

The Creators Update includes a includes a new tool, mbr2gpt, which converts an MBR volume to a GPT volume WITHOUT modifying or deleting data on the disk.

Winaero has an article with the complete instructions. It's not trivial but it's easier that what I did.
