Windows 7: How to make 1 large partition on a 2 TB external HDD

How to make 1 large partition on a 2 TB external HDD

I have a 2 Tb Hdd in an external enclosure that I formatted when I first got it. Formatting as NTFS in Windows gave me 2 partitions; (OS) I is listed as 465 Gbs (has an old backup); the other is (K) 1.36 TB. I want the entire Hdd as 1 large storage unit. How to remove the (OS) I partition without moving data or deleting the large K partition; is it possible?

Normally, you'd boot from C on Disk 0, go to Windows Disk Management, right click on I and delete it. Then use something like Partition Wizard to add that freed up space to K.

But I see that disk 1 is "dynamic". Not good. You'd want it to be "basic", like the partitions on Disk 0. Dynamic partitions are not standard, so you must have explicitly chosen dynamic at some point.

So, I'd try to get rid of dynamic partitions altogether.

Certain applications supposedly can convert from dynamic to basic without moving data, but I'd be afraid of that. The better idea would be to copy whatever is on K to some other drive entirely and then delete all partitions from Disk 1 and remake partitions as necessary, all as "basic".

Large external HDD for backup - Partition? Image and Synctoy?
I have an all-in-one desktop computer with a 1 TB internal HDD. When I first got the computer, I did not understand how helpful it would have been to create a separate partition just for my data. Because of the location of the OEM partition, I would have had to use a third-party program to move...
