When my PC was new the hard drive was 120GB and this is what it says on the bill of sale. I also remember seeing this some where in my PC a long time ago. Today I was reading an article on Gizmo's site about partitioning the hard drive and when I hovered my mouse over the C drive icon in My Computer it said 111GB total with 89.5GB free. Not that I need the missing 9GB or anything but it started me thinking where has it gone?. It may be a stupid question but can anyone explain this to me?.

I have the same thing with an older WD 120Gig drive.

Got curious when I first discovered it myself so I did some digging. What I read is that the manufacturers of the HDD and MS did the math a little different. The manufacturer says 1GB = 1024 MB. Microsoft does the math as 1 GB = 1000 MB.

I think that is about right. Never dug any deeper and always planned on replacing the drive with a larger one anyways.

Sure.

The stated size of a drive by vendors...is misleading, due to the way Windows works.

Take a look at the entire article, http://wdc.custhelp.com/cgi-bin/wdc.cfg/ph...php?p_faqid=615.

Thanks Hamlouis, according to the post 120GB = 111.76GB which my PC has rounded off to 111GB.
