How to retrieve space on second hard drive.

My main PC has the following set up. SSD for Windows and programs and second hard drive for data like so:



I have a new Laptop well 10 months old but never used other than keeping A/V and updates current. It has the same setup as my main PC namely SSD and second hard drive for Data. It seem as if i hav lost most of the second hard drive space. Can't say for certain that that is how it came dfrom the suppliers but I certainly have not inteferred with the partitioning. The disk management shows this:


Whereas the Windows Explorer shows this:

Is this just a case of sorting the partitions? If so any help would be appreciated.

Can't see why my last screenshot does not show. It is here:



Sorry original got corrupted!

Hmmm.....Disk Management says disk 1 partition D is named "Recovery" and is 931 GB.

But the upper part of Disk Management says D is less than 6 GB.

Normally, I'd expect the recovery partition to be on the same drive as C.

What results do you show if disk 1 is connected to some other port or even some other PC?

If you drill into Explorer, do you see what appears to be "recovery" files on D or on that small partition on disk 0?

It looks like D is "Recovery" in name only---perhaps named that by accident?

If you believe the recovery partition is in fact on disk 0 not disk 1, then can you simply delete partition D and attempt to reformat it?

Can you copy say 10 GB of files to D to see if it's capacity is in fact less than 6 GB?

Can you simply give D some other name and does that have any affect on stated capacities?

Many thanks for your response. Have answered each question, I hope fully. I'm thinking this is going to be a re-install. Wouldn't be problem as I said this laptop has no data and no programs installed apart from A/V. look forward to you further comments.

This partition has a folder named "Recovery" and the usual files you would expect. Clicking "Properties shows it to have a capacity of 5.86GB

Agree, that's where it is on my main rig

It's a laptop so I can't easily try that

Don't get the normal context menu so cannot open of explore that drive. Just get the word "Help" Quite appropriate really!

Sorry for the delay in getting back but got called away.
Using an elevated command prompt many times i have now got this:



Got to grips with "unallocated" partition and creating new via diskpart and marking partions as active/inactive.
Am now cearting a Macrium beckup in case i need to get beck to this position. All in all a successful job. Many thanks to all!
