How do I combine Local Disk C and D into one

[Change_Later]

I was wondering how to combine local disk c and d into one. I’ve tried the most common method of opening disk management, deleting disk d and extending c but it won’t let me extend. Also I’m not concerned about losing data since there is nothing on my pc.

First question would be: are C & D on the same physical drive as separate partitions, or are they physically separate drives?

Ones is an ssd in SATA 1 and the other is a Hdd in SATA 2

while you COULD create a spanned volume it WOULDN'T be recommended with that combination. Before drive 2 is used in a spanned volume drive 1 is filled up. Too much uneccessary wear and tear on your SSD for leveling if you don't have any of the drive free.

People normally only combine volumes if they are both on the same physical drive, and the two volumes must be adjacent to each other otherwise it can't be done.

The "spanning" option with two separate physical drives is not worth even considering.

So is there a way I could have documents, pictures, videos etc automatically save onto drive d then? Make that my storage drive

Yes, you can change the default save location for files. Below are links to a couple to tutorials on how to do that in Windows 10.

So just to double check, if I had two SSDs or HDDs which were physically the same I could combine them into 1 local drive. Right?

That's called "spanning" and is not recommended for the reasons mentioned previously.

Absolutely. Read here:

In theory, yes.
But for a variety of reasons, it it NOT a good idea.
