SSD size post cloning

[rodorr]

Recently successfully cloned system HDD to SSD.
Am now booting off SSD and everything seems fine

Before i format the old HDD and erase all old data I did a quick check to see if everything was across and got confusing info.

For example if I use explorer and look at properties of the SSD drive i get 47.2GB used space. Then looking at the HDD I get 57.5GB used space.

If I then compare used space, folder by folder of the root directory of each I get roughly equivalent results

I'm pretty confident everything came across, but I think I must be missing something pretty basic. Can anyone explain the reported discrepancy at the drive level?

P.S. have removed compression off both drives

Is your page file a different size on one of the drives? What about hiberfil.sys?

You could use a program like WinDirStat to find out the source of the discrepancy.

both those files are similar in size
will have a look at WinDirStat

Thanks for the tip on WinDirStat
I ran it and it showed both drives basically the same. In fact the SSD was less than 1gb larger in file size. This is understandable as I have downloaded a couple of programs and some other things.

This still leaves why explorer when showing properties of a "drive" shows such a big difference. The drive properties panel is different from the folder/file properties panel so maybe it is showing something different for "used space"

Could it have something to do with allocated sectors/sizes being different?
A 20% difference though would seem to be unusual. At least it makes the SSD seem to be more space efficient.
