Windows 7: Missing total space from hard drive.

I have two partitions in my computer, which is C: (34.9GB) and D: (263.1GB) It makes a total of 298GB. I thought that I will make another partition out of D: which I did, and came out with H: (28.1GB), and again made another partition out of H: and came out with I: (13GB).

Now I have four partitions C: (34.9GB) D: (235GB) H: (15.10GB) and I: (13GB).

I was happy at first, then suddenly when I opened My Computer, drive D: now only has 234GB, H: with 15GB flat and I: has 12.9GB! (I clicked on properties and those are the total amounts of space that came out)

I lost a total of 1.2GB, and now I only have a total of 296.8GB!

I know it's not that big, but it still gives me headache when I see that I have a missing hard drive total space.

I opened Disk Management and I saw no "unallocated space." But, when I looked at drive D: H: and I: the Disk Management shows the amount it should be (235, 15.10, and 13 GB) Why is it like that? And why does My Computer shows different total space? And if there is really something wrong, how could I recover the missing space? Please help. Thank you in advance.

Hello there!


Something's not adding up. You say you have four partitions C: (34.9GB) D: (235GB) H: (15.10GB) and I: (13GB). They add up to 298GB.


Then you say drive D: now only has 234GB, H: with 15GB flat and I: has 12.9GB! (I clicked on properties and those are the total amounts of space that came out) I lost a total of 1.2GB, and now I only have a total of 297.8GB!


297.8GB + 1.2GB = 299GB. Are you sure you didn't lose just .2GB (about 200MB)? That could easily be explained if you're rounding off to tenths of a gigabyte (eg: 297.8GB whereas computer might be rounding off to hundreths of a gigabyte - 297.82GB).


It would help to clear up the mystery if you could post a screenshot of your expanded disk manangement.

Oh, sorry about that. It should be 296.8GB, and I'm pretty sure I lost 1.2GB. And is this the screenshot you're looking for?

34.99 plus 235.00 plus 15.10 plus 13.00 is 298.09.

What's wrong with that?

Because when I open My Computer it shows less total space.

And if you use some other program such as Partition Magic, it might show another set of slightly different numbers.

I'd forget about it--that's better than laying awake at night wondering about it.

It shows the same as Disk Management shows. I just want to know what happened to the missing space.

I wouldn't suppose anything is "missing".

Who's to say the larger number is correct? Maybe it is "wrong". Then you could wonder about why you have "extra" space..

Different programs measure different things. I've seen instances in which certain programs don't even show small "unallocated" spaces at the beginning and end of drives. That doesn't mean something is "wrong".

It's the instrument used to measure the disk. They aren't created equally. They see different things.

So, it means I may still have that 298GB and it just don't show up as a total of 298GB?

Doesn't windows reserve a percentage at the beginning of each partition?
