Thanks, Brian
All my HDDs don't exceed 2TB( MBR format by choice) so my comment is an opinion.
My understanding is that your OS drive can be MBR and large (> 2TB) data drives formatted GPT should be fully compatible. If you convert your 4 TB drive to MBR then I think you will only see 2TB. So > 2TB for data drives then GPT is the way.

Now ask the more unknown question concerning Macrium system imaging. Can you create a macrium (free) system image on a GPT data drive and restore to the MBR OS drive. I think you can ????

So, you`re saying you think the entire 4 TB drive initialized GPT would be seen by windows no problem ? No separate partitions, just one astronomically huge galaxy sized mind boggling partition.

2nd paragraph here clearly states: GUID Partition Tables (GPT) can define drives larger than 2.2TB. You can use GPT today on any Windows 10/ 8.1/8/7 and Vista system as a non-booting data drive. Windows can only boot a GPT partition on a new type of BIOS called UEFI.

Yeah, i just wanted to get with the times. I assumed everything would behave. The feature is there - it should work!

I learned a fair amount, but boy did i waste a lot of time

I didn't say no problems. I am basing my comments on what I have read. But if you have a new 4 TB HDD (I don't) then play around with it as a data drive formatted GPT. If I had such a large HDD then I'd personally partition it.

The GUID/GPT is a newer standard for the partitioning table layout. The MBR partition table lives in the first 512 MBR bytes on the disk and is more restricted and doesn't support large drives > 2TB.

There is a difference between the boot drive and additional data drives. If you want to boot to a drive > 2TB then you need UEFI/GPT booting. Why you want to have a really big boot drive is beyond me.

My understanding is that you can have an MBR boot/OS drive and GPT data drives when they exceed 2TB.
Others with more first hand experience may want to comment.

Yes you can have a MBR boot/OS drive and GPT data drives.
For drives > 2 TB they must be GPT or Windows won't be able to use all the space.

As far as partitioning that is a personal choice.
It depends on how a person is going to use the drives.
I use large drives as "Backup/Archive" drives that are normally offline.
I don't partition them, i use folders to organize data.

If i used them online and some data changed daily i probably would do some partitioning.
With partitioning you can better control scans and maintenance such as security programs, defrag, update checkers, etc.
For me i don't need these type of scans done regularly on "static" data that doesn't often change.

I use 1 TB or smaller drives for online data drives.
If i had larger drives online, i'd somehow fill it with data that i really don't need everyday.
This way i force myself to do better at keeping online data lean and clean

Getting rid of dual boot and fresh install of Win7
