Recently i just reinstalled my 80GB (2 partitions) hardisk with Window XP SP2. After I installed other programs & stuffs, & when I check the properties of the drive, I found that my hardisk is just 12% free space left. SO, I click into the drive & select all the files & folders inside including the hidden 1, it just total up to 9GB plus, almost 28GB gone. Why is this happen? How can I fix it? Plz help~!!!

Can you please give us more information?

What brand of computer is this? What are the sizes of the 2 partitions?
