Just bought a new computer with 80 MB, but the "my computer" windows shows 63 in C drive, and 10 in D.  Also, there is nothing in the D drive yet it says 9.38/10 GB REMAIN.  C drive has 51.5/63 GB. I understand the C drive has programs installed and eats up the memory, but why starting off from 63 and not 70?  And so then, what is eating up .62 GB in the D drive??

I've heard the computer computes GBs in a different way which leads to this...

Any explanations?

That article may be of USE.

What operating system is installed? If you use /Fdisk you may run into some strange Hard Disk Drive SIZES if you donot properly use the tool.SOrry, Windows XP.  F disk?  You mean format?  Everything came preinstalled.
LEt me take a look at the article, and thanks!It is not uncommon for larger Hard Disk Drives to miss a few Gigabytes.. It all has to do with sectors and the like, someone more experienced can tell you more about that.
