That 160GB is in BILLION BYTE units. Sadly giga in Windows is not a decimal standard. Read Consumer Confusion at http://en.wikipedia.org/wiki/Gigabyte
160 / 1.073741824 = 149.011 so you'll have to redo your work.
There will also be a recovery partition you need to add in.

Hi,
I recently purchased Toshiba Laptop which 160 GB Harddisk. There is some portion of harddisk which i am not able to account for.
When I select all the programs (Control + A), The disk space used shows about 15 GB. But When I see the Space graph in the My Computer It Shows 112 GB FREE OF 147 GB. So I am not able to account for 35GB(147-112) + 13 GB(160GB-147GB) = 48GB - 15GB = 32 GB.
Can someone help me out. Where is my space getting used.
