750GB drive shows as only 365GB drive - where's the rest of it?

It looks like absolutely nothing is on E, the 348.77 gb partition.

Is that correct?

If so, just delete it.

You should then have close to 700 GB of unallocated space.

Then make one new partition that takes up ALL of the unallocated space.

You should be able to do that with a few mouse clicks in Disk Management.

You will have to then format this new partition.

Make the new partition and post another picture.

Thanks - I think this is what I'm looking for, correct? Almost 700GB but not quite.

You just won a cigar.

All you have to do is format it.

Isn't it already formatted? It does say NTFS

Yeah, I didn't catch that in the pic.

Partitions have to be formatted to be used. A quick format takes seconds. A full format can take hours.

OK, I should be good to go then - can I now mark this as solved?

Sure, assuming you have no further issues.

I'd give that new drive a more descriptive name, but it's your choice.

Hey, thank you very much! Yeah, not much flair in that name, is there?
