Can I safely reformat an empty partition to reclaim "used" space?

My laptop came with a single SATA HDD that was partitioned into a C:\ and a D:\ drive.

I haven't used my D:\ until now that my C:\ has filled up. Once that happened, I dragged and dropped the 'My Documents' folder into the D:\ drive - then thought better of it, dragged it back into C:\ and came onto a forum for advice on how best to go about it.
Before all this action, the D:\ was always shown as having "Used Space: 0MB, Capacity: 72GB". After all the dragging-and-dropping to and from C:\, however, D:\ supposedly has "Used Space: 192MB, Capacity: 71.8GB".

I tried to return D:\ to its completely empty state by clearing it out, viewing and removing hidden files, using Disk Clean-up, running Defrag, etc. But it still shows as having "Used Space: 192MB, Capacity: 71.8GB"!

Why is this?
I mean, I know that amount of usable disk space is not always as advertised, but how come D:\ used to be able to to show 0MB used space, but now has to show 192MB used space even though it is just as empty as before?!

So now I'm thinking of reformatting D:\.
But since D:\ is just a partition within a drive, won't reformatting it affect my C:\ as well? If so, how?
Are there any (other) dangers to re-formatting the D:\ partition?
How do I even go about reformatting just the D:\ partition safely? (I really don't want to touch C:\ ...)

Finally, is there any other way that I can 're-claim' those 192MB?
(I know 192MB isn't much compared to the 71.8GB I've got left, but it's still a good 2 or 3 music-album's worth of space ...)

Thanks in advance! Any help is much appreciated!

Edit:
Bw, the defrag analysis offered the following info:

Volume ACERDATA (D:)
Volume size = 72.04 GB
Cluster size = 4 KB
Used space = 216 MB
Free space = 71.83 GB
Percent free space = 99 %

Volume fragmentation
Total fragmentation = 0 %
File fragmentation = 1 %
Free space fragmentation = 0 %

File fragmentation
Total files = 108
Average file size = 2 MB
Total fragmented files = 1
Total excess fragments = 6
Average fragments per file = 1.05

Pagefile fragmentation
Pagefile size = 0 bytes
Total fragments = 0

Folder fragmentation
Total folders = 13
Fragmented folders = 1
Excess folder fragments = 0

Master File Table (MFT) fragmentation
Total MFT size = 12 MB
MFT record count = 136
Percent MFT in use = 1 %
Total MFT fragments = 3
(things in bold are by me)

This just reiterates my question tho:
What and where are those 108 Total files and/or 13 Total folders?

You can safely reformat your D: drive without affecting your C: partition. Right Click My Computer -> Click Manage -> Disk Management -> Storage -> Right Click the D: partition and click Format. Format the partition as NTFS.

The folders you mentioned my be hidden. Before reformatting the partition, browse to the drive location and click "Tools" on the Menu Bar. You may need to press the "alt" key to view the Menu Bar. Then click Folder Options -> View -> Click "Show hidden files and folders." You may also want to uncheck the "Hide protected operating system files" box. Those steps may allow you to see the folders.

Do you have a factory recover disk for the laptop?
