Hard-Disk Space

[Jimmy]

Hello,
Last night i checked my computer hard-drive and it was 75 gb free space and
now today it is 63.3gb free,

I have also selected every folder in my C: drive and clicked properties and
it shows that my harddisk actually has only used 30gb

I have a 111gb drive (meant to be 120gb)
So do the maths

111gb - 30gb = 81gb and it says that i only have 63.3gb???
Whats going on??

Thanks,
Jimmy

I guess, you should just check your disk if there are any errors...
For example, by NDD(NU) or even Scandisk...
Errors on the disk can cause incorrect free space be shown up...

Remember also that a 120GB drive when formatted won't appear as 120GB's -
more like 114GB's

Thanks guys/gals,
I found out the problem,
I have Norton Anti-Virus 2003 installed, and it "plurges" all installed and
uninstalled files to a maximum amount set by Norton,
I had to right-click recycling bin, go to properties and find plurge files
settings,
I then found that norton was using 40% maximum to do this, i put it down to
5% and tada....my C: went back upto 88gb free space.
I hate new software that makes inconviences, as this computer i have is used
for video productions, and every bit of space is needed.

Also, I am sorry for cross posting, as I was worried and wanted as much help
as possible, Please forgive me.
And yes, i know that Richard, as mine was formated 111gb

Thanks again everyone,
Jimmy

I suspect a data minining package. run Ad-aware - a free version is
available on their site - http://www.snapfiles.com/get/adaware.html

No, the issue is not formatting. All hard drive manufacturers
define 1GB as 1,000,000,000 bytes, while the rest of the computer
world, including Windows, defines it as 2 to the 30th power
(1,073,741,824) bytes. So a 120 billion bye drive is actually a
little under 112GB.

Some people point out that the official international standard
defines the "G" of GB as one billion, not 1,073,741,824. Correct
though they are, using the binary value of GB is so well
established in the computer world that I consider using the
decimal value of a billion to be deceptive marketing.

Confusion will continue while the meaning of G is context-sensitive:

G = 1,073,741,824 in GB (always for RAM, sometimes for disk)
G = 1,000,000,000 in Gb (e.g., GbE)
G = 1,000,000,000 in GHz (on this, we're consistent)

Sigh. M$ at least helps by sometimes reporting HD sizes in binary GBs
and in non-argumentative Bs.

You're kidding. The word is "purge" by the way.

Correct.

All hard drive manufacturers define 1GB as 1,000,000,000
bytes, while the rest of the computer world, including Windows,
defines it as 2 to the 30th power (1,073,741,824) bytes.

Incorrect. The decimal form is used in quite a few
other areas than just hard drives, most obviously
with cpu speeds, and some things are a weird
decimal/binary hybrid like the 1.44MB floppy.

So a 120 billion bye drive is actually a little under 112GB.

Some people point out that the official international standard
defines the "G" of GB as one billion, not 1,073,741,824.

You are in fact grossly overstating that.

that I consider using the decimal value
of a billion to be deceptive marketing.

More fool you when the decimal form
has always been used for cpu speeds.

Its all fixed now, read my post above
